1 00:00:06,690 --> 00:00:07,650 - [Instructor] For this first part 2 00:00:07,650 --> 00:00:09,750 of the video troubleshooting lesson, 3 00:00:09,750 --> 00:00:13,080 I wanna talk about some things that you can check 4 00:00:13,080 --> 00:00:15,240 within the video subsystem, 5 00:00:15,240 --> 00:00:18,270 and what those things might fix for you. 6 00:00:18,270 --> 00:00:20,190 And we'll start with connections. 7 00:00:20,190 --> 00:00:23,250 Just like we always do, always check the connections. 8 00:00:23,250 --> 00:00:25,770 If nothing is showing up on the display, 9 00:00:25,770 --> 00:00:27,360 first make sure that the monitor 10 00:00:27,360 --> 00:00:29,430 is plugged into the video card 11 00:00:29,430 --> 00:00:32,490 and to the correct video port. 12 00:00:32,490 --> 00:00:34,500 And then verify that the monitor is connected 13 00:00:34,500 --> 00:00:38,490 to the AC outlet, and make sure it's powered on. 14 00:00:38,490 --> 00:00:41,310 If the image on the display is scrambled, 15 00:00:41,310 --> 00:00:42,780 check that it is connected 16 00:00:42,780 --> 00:00:45,810 to the correct port on the video card also. 17 00:00:45,810 --> 00:00:48,150 If necessary, try removing the video card 18 00:00:48,150 --> 00:00:51,063 and reseating it carefully if need be. 19 00:00:52,200 --> 00:00:54,720 Then there's power cycling the video devices. 20 00:00:54,720 --> 00:00:58,290 A proper power cycle means you're turning them off 21 00:00:58,290 --> 00:01:00,450 and disconnecting the power, 22 00:01:00,450 --> 00:01:02,370 and then waiting a couple minutes, 23 00:01:02,370 --> 00:01:04,710 then plugging them back in and turning them back on. 24 00:01:04,710 --> 00:01:08,280 So power cycle the computer, the display, 25 00:01:08,280 --> 00:01:11,640 and any power protection equipment also. 26 00:01:11,640 --> 00:01:15,450 Power cycling the equipment can fix all kinds of problems, 27 00:01:15,450 --> 00:01:18,090 and it's an easy solution to implement. 28 00:01:18,090 --> 00:01:20,280 Problems such as video memory, 29 00:01:20,280 --> 00:01:22,260 also known as image retention, 30 00:01:22,260 --> 00:01:26,160 and also stuck pixels might be easily repaired 31 00:01:26,160 --> 00:01:29,430 by a power cycle of the display and the computer 32 00:01:29,430 --> 00:01:32,940 and any surge suppressor that the equipment is plugged into. 33 00:01:32,940 --> 00:01:35,040 You might also need to leave the display off 34 00:01:35,040 --> 00:01:40,040 for a couple of hours to fix a video memory problem. 35 00:01:40,140 --> 00:01:43,110 Now, video memory and image retention 36 00:01:43,110 --> 00:01:46,590 are sometimes also referred to as burn in, 37 00:01:46,590 --> 00:01:49,500 but that's actually a symptom of a problem 38 00:01:49,500 --> 00:01:53,220 that occurs in the older CRT monitors, 39 00:01:53,220 --> 00:01:55,590 the cathode ray tube monitors. 40 00:01:55,590 --> 00:02:00,450 And CRT isn't on the objectives for the 901 exam. 41 00:02:00,450 --> 00:02:04,170 It's the LCDs that you're interested in for the exam, 42 00:02:04,170 --> 00:02:08,490 and it's really known as video memory or image retention. 43 00:02:08,490 --> 00:02:11,703 So try power cycling the equipment for that. 44 00:02:12,900 --> 00:02:15,390 Next is checking the onboard video. 45 00:02:15,390 --> 00:02:20,340 Check for an onboard video setting in the UFI or the bios. 46 00:02:20,340 --> 00:02:23,490 If you install a new video card to a computer 47 00:02:23,490 --> 00:02:26,700 that previously used onboard video, 48 00:02:26,700 --> 00:02:29,250 always check that the onboard video setting 49 00:02:29,250 --> 00:02:31,560 is disabled in that bios. 50 00:02:31,560 --> 00:02:34,680 It could conflict with the new video card. 51 00:02:34,680 --> 00:02:36,930 And also be sure to plug the monitor 52 00:02:36,930 --> 00:02:41,250 into the new video card, not the old onboard connection. 53 00:02:41,250 --> 00:02:42,750 You know, in this scenario, 54 00:02:42,750 --> 00:02:45,630 you might have two DVI connections, 55 00:02:45,630 --> 00:02:48,300 one that's on the motherboard, integrated, 56 00:02:48,300 --> 00:02:49,710 and one that's on the new video card, 57 00:02:49,710 --> 00:02:52,493 so you have to make sure you're connecting to the right one. 58 00:02:54,120 --> 00:02:56,580 Next is checking the resolution setting. 59 00:02:56,580 --> 00:02:59,190 If the resolution was set too high 60 00:02:59,190 --> 00:03:03,060 or was set to a resolution not supported by the monitor, 61 00:03:03,060 --> 00:03:07,380 you might get a distorted image or no image at all. 62 00:03:07,380 --> 00:03:09,180 So what you could do is you can boot 63 00:03:09,180 --> 00:03:12,990 into low resolution VGA mode or safe mode, 64 00:03:12,990 --> 00:03:16,050 and these are found in the advanced boot options menu 65 00:03:16,050 --> 00:03:18,000 in Windows 7 and Vista, 66 00:03:18,000 --> 00:03:22,410 and that's known as startup settings in Windows 8. 67 00:03:22,410 --> 00:03:24,630 And what this does is it starts the computer 68 00:03:24,630 --> 00:03:26,790 with the resolution of 640 by 480, 69 00:03:26,790 --> 00:03:30,990 a basic VGA driver that'll run no matter what. 70 00:03:30,990 --> 00:03:33,930 Then what you do is you modify the resolution setting 71 00:03:33,930 --> 00:03:36,390 in the screen resolution window. 72 00:03:36,390 --> 00:03:37,893 So I'll bring that up now. 73 00:03:39,210 --> 00:03:40,980 And here's my screen resolution window. 74 00:03:40,980 --> 00:03:43,110 I'm running two monitors on this. 75 00:03:43,110 --> 00:03:46,110 This guy's running at 1900 by 1200. 76 00:03:46,110 --> 00:03:48,270 Well, let's say the monitor couldn't handle that. 77 00:03:48,270 --> 00:03:53,270 Let's say that it could only handle maybe 1680 by 1050. 78 00:03:54,150 --> 00:03:56,340 Well, you could boot into that safe mode, 79 00:03:56,340 --> 00:03:59,970 which starts with a basic VGA driver at 640 by 480, 80 00:03:59,970 --> 00:04:03,153 and just reduce the slider here to what you need. 81 00:04:04,290 --> 00:04:05,670 And the same for any other monitors 82 00:04:05,670 --> 00:04:07,320 that you have on the system. 83 00:04:07,320 --> 00:04:09,303 So that's a way of getting around that. 84 00:04:10,410 --> 00:04:14,520 Lower resolutions will result in oversized icons. 85 00:04:14,520 --> 00:04:15,630 Sometimes you'll see people 86 00:04:15,630 --> 00:04:18,570 with the resolution set real low, 87 00:04:18,570 --> 00:04:22,170 and you can see that makes the screen appear smaller here. 88 00:04:22,170 --> 00:04:26,610 That's gonna make the icons and the images look really big, 89 00:04:26,610 --> 00:04:30,360 oversized, and it'll make it difficult for the typical user 90 00:04:30,360 --> 00:04:33,720 to view all the information required on one screen. 91 00:04:33,720 --> 00:04:36,060 For example, if you're using a big database 92 00:04:36,060 --> 00:04:38,550 or a big spreadsheet program, 93 00:04:38,550 --> 00:04:41,190 or if you're doing audio video editing. 94 00:04:41,190 --> 00:04:45,090 So simply increase the resolution setting 95 00:04:45,090 --> 00:04:46,890 to fix that problem, 96 00:04:46,890 --> 00:04:51,480 and that'll give you more screen area effectively, 97 00:04:51,480 --> 00:04:54,543 and make all of your image and icons appear smaller. 98 00:04:56,250 --> 00:05:00,270 Next is to check the driver, maybe the driver failed 99 00:05:00,270 --> 00:05:01,830 or perhaps the wrong driver 100 00:05:01,830 --> 00:05:04,260 was installed during installation, 101 00:05:04,260 --> 00:05:07,230 or maybe an update to the driver is necessary. 102 00:05:07,230 --> 00:05:09,390 If there's nothing on the display 103 00:05:09,390 --> 00:05:11,460 or if the image is distorted, 104 00:05:11,460 --> 00:05:15,060 or if the monitor only displays a lower resolution, 105 00:05:15,060 --> 00:05:18,930 you can once again, boot into low res mode or safe mode 106 00:05:18,930 --> 00:05:22,470 and update the driver from within a device manager, 107 00:05:22,470 --> 00:05:24,600 or you could do it from a variety of other places. 108 00:05:24,600 --> 00:05:26,100 For example, if you're, you know, 109 00:05:26,100 --> 00:05:28,500 we were just in the screen resolution area. 110 00:05:28,500 --> 00:05:30,660 We could go to advanced settings, 111 00:05:30,660 --> 00:05:33,620 and you see the adapter for the video card here. 112 00:05:33,620 --> 00:05:38,190 This is the GeForce GT 630, and we could go to properties 113 00:05:38,190 --> 00:05:39,960 and then go to the driver tab for that 114 00:05:39,960 --> 00:05:41,820 and update the driver from there, 115 00:05:41,820 --> 00:05:43,530 or roll it back if necessary 116 00:05:43,530 --> 00:05:45,933 if the new update causes you problems. 117 00:05:47,490 --> 00:05:49,320 So there's a lot of places to go there. 118 00:05:49,320 --> 00:05:51,540 And driver failures could also be the cause 119 00:05:51,540 --> 00:05:52,680 of a blue screen of death. 120 00:05:52,680 --> 00:05:55,560 So, you know, your video driver could be the cause of that. 121 00:05:55,560 --> 00:05:57,990 So remember that you can boot into safe mode 122 00:05:57,990 --> 00:05:59,973 to modify those drivers. 123 00:06:01,260 --> 00:06:04,110 Next check the DirectX version. 124 00:06:04,110 --> 00:06:08,100 DirectX is a windows technology that includes video, 125 00:06:08,100 --> 00:06:10,680 animation, and sound components. 126 00:06:10,680 --> 00:06:13,170 It helps a computer get more performance 127 00:06:13,170 --> 00:06:16,113 out of multimedia and games and movies. 128 00:06:17,220 --> 00:06:21,780 The DirectX diagnostic tool, or DX Diag, 129 00:06:21,780 --> 00:06:26,010 helps you to troubleshoot any DirectX related issues. 130 00:06:26,010 --> 00:06:27,570 And it'll tell you what version you're running, 131 00:06:27,570 --> 00:06:29,490 and you can update it also. 132 00:06:29,490 --> 00:06:30,840 The tool gives you information 133 00:06:30,840 --> 00:06:34,080 about whether it's operating correctly, 134 00:06:34,080 --> 00:06:35,820 and that can be started 135 00:06:35,820 --> 00:06:38,940 by opening the run prompt and typing DX Diag. 136 00:06:38,940 --> 00:06:41,160 And you'll get a window that looks like this, 137 00:06:41,160 --> 00:06:43,413 your DirectX diagnostic tool. 138 00:06:44,310 --> 00:06:46,953 And this one here is running DirectX 11, 139 00:06:49,140 --> 00:06:50,820 Windows 7 and 8 use 11. 140 00:06:50,820 --> 00:06:52,560 But you know, you can always upgrade 141 00:06:52,560 --> 00:06:54,360 to newer versions as they're released 142 00:06:54,360 --> 00:06:57,540 as long as the update for the operating system is included, 143 00:06:57,540 --> 00:06:59,610 is running, I should say. 144 00:06:59,610 --> 00:07:01,980 So on the main screen you have your system, 145 00:07:01,980 --> 00:07:05,310 and it tells you a whole good deal of information here. 146 00:07:05,310 --> 00:07:07,293 It tells you to DirectX version. 147 00:07:08,160 --> 00:07:10,290 And then you can find out more information 148 00:07:10,290 --> 00:07:12,120 about each display 149 00:07:12,120 --> 00:07:15,600 and whether there are any DirectX problems, 150 00:07:15,600 --> 00:07:18,420 and you might have a problem with direct 3D acceleration, 151 00:07:18,420 --> 00:07:20,250 and then you're gonna have problems working 152 00:07:20,250 --> 00:07:22,620 with a lot of applications and games. 153 00:07:22,620 --> 00:07:24,120 Direct draw acceleration, 154 00:07:24,120 --> 00:07:26,010 I actually disabled that on this system 155 00:07:26,010 --> 00:07:28,020 'cause I don't need it, but if you're playing games 156 00:07:28,020 --> 00:07:31,740 or doing AutoCAD or something like that, 157 00:07:31,740 --> 00:07:34,620 then you might see some issues down here. 158 00:07:34,620 --> 00:07:36,618 First of all, if it's disabled, 159 00:07:36,618 --> 00:07:38,190 it's not gonna work very well, those programs, 160 00:07:38,190 --> 00:07:40,260 and you might see some issues down here as well 161 00:07:40,260 --> 00:07:43,380 that you can troubleshoot further with the event viewer, 162 00:07:43,380 --> 00:07:45,570 and you know, by upgrading DirectX 163 00:07:45,570 --> 00:07:47,580 and upgrading the driver for the display 164 00:07:47,580 --> 00:07:49,140 and for the video card. 165 00:07:49,140 --> 00:07:50,190 And I have two displays, 166 00:07:50,190 --> 00:07:51,930 so it's showing both here. 167 00:07:51,930 --> 00:07:54,180 It also gives you some information about your audio 168 00:07:54,180 --> 00:07:55,380 and your input devices. 169 00:07:55,380 --> 00:07:58,710 So pretty cool tool to use, that's DirectX. 170 00:07:58,710 --> 00:08:02,040 And again, you can go to run prompt to type DX Diag 171 00:08:02,040 --> 00:08:04,653 to get in there, that's DX D-I-A-G. 172 00:08:05,490 --> 00:08:08,370 Next, check the temperature of the card. 173 00:08:08,370 --> 00:08:10,950 Check the temperature threshold. 174 00:08:10,950 --> 00:08:13,980 High end video cards are intensely used 175 00:08:13,980 --> 00:08:15,990 by gamers and designers. 176 00:08:15,990 --> 00:08:19,680 If the temperature surpasses the safeguards in place, 177 00:08:19,680 --> 00:08:24,030 it might cause the card to throttle back the GPU speed, 178 00:08:24,030 --> 00:08:26,520 or the video card might stop working altogether. 179 00:08:26,520 --> 00:08:29,520 And that could cause the current application to crash, 180 00:08:29,520 --> 00:08:32,730 or it to close, or the display could go blank. 181 00:08:32,730 --> 00:08:34,620 So if this happens more than once or twice, 182 00:08:34,620 --> 00:08:37,920 consider additional cooling fans in the case 183 00:08:37,920 --> 00:08:41,910 or liquid cooling system or possibly a better video card 184 00:08:41,910 --> 00:08:43,713 if it's just being used too much. 185 00:08:45,750 --> 00:08:50,750 Use software to check and repair stuck or dead pixels. 186 00:08:51,690 --> 00:08:55,740 When a single pixel fails, it could be very irritating, 187 00:08:55,740 --> 00:08:58,440 but there are third party software programs out there 188 00:08:58,440 --> 00:09:00,780 that could be used to identify stuck pixels 189 00:09:00,780 --> 00:09:04,320 and possible dead pixels in an attempt to fix them. 190 00:09:04,320 --> 00:09:08,850 If you go on Google or Yahoo and do a search for LCD repair 191 00:09:08,850 --> 00:09:11,790 or dead pixel repair or a similar term, 192 00:09:11,790 --> 00:09:14,820 you'll find some third party programs out there. 193 00:09:14,820 --> 00:09:17,520 But always try power cycling the device first. 194 00:09:17,520 --> 00:09:20,560 If you can't repair the stuck or dead pixel 195 00:09:21,420 --> 00:09:24,360 with power cycling or with third party software, 196 00:09:24,360 --> 00:09:26,340 then you might have to bring the display back in 197 00:09:26,340 --> 00:09:28,653 for repair or replacement. 198 00:09:30,870 --> 00:09:32,700 Next, calibrate the monitor. 199 00:09:32,700 --> 00:09:35,640 If you see any artifacts or image distortions 200 00:09:35,640 --> 00:09:38,850 or you notice incorrect color patterns 201 00:09:38,850 --> 00:09:40,770 or the display just doesn't seem to look 202 00:09:40,770 --> 00:09:43,890 quite as good as it used to, try calibrating the monitor 203 00:09:43,890 --> 00:09:48,890 by either resetting it from the onscreen display 204 00:09:49,080 --> 00:09:51,510 or by adjusting the contrast, 205 00:09:51,510 --> 00:09:54,360 the brightness, and the color level. 206 00:09:54,360 --> 00:09:58,560 Also you can try adjusting the color depth in Windows 207 00:09:58,560 --> 00:10:00,480 and check that screen resolution again. 208 00:10:00,480 --> 00:10:02,880 You know, we talked about the screen resolution. 209 00:10:06,840 --> 00:10:08,690 And if we go to the advanced settings 210 00:10:09,690 --> 00:10:13,200 and go to the monitor tab, you have that color depth. 211 00:10:13,200 --> 00:10:14,970 You know, maybe it's running at 16 bit 212 00:10:14,970 --> 00:10:17,430 and your applications really need 32 bit 213 00:10:17,430 --> 00:10:19,200 to really look sharp. 214 00:10:19,200 --> 00:10:21,060 You know, this is gonna be especially important 215 00:10:21,060 --> 00:10:22,530 if you're a graphics designer 216 00:10:22,530 --> 00:10:25,500 or if you're dealing with photo editing software 217 00:10:25,500 --> 00:10:26,970 or other video editing, 218 00:10:26,970 --> 00:10:28,983 you're gonna wanna set this to 32 bit. 219 00:10:32,310 --> 00:10:33,663 So check those things, 220 00:10:35,010 --> 00:10:37,683 try to limit reflections on the screen. 221 00:10:39,030 --> 00:10:42,210 You know, make sure you're using an LCD 222 00:10:42,210 --> 00:10:44,673 that has a decent screen. 223 00:10:45,960 --> 00:10:47,550 Dim images could also be caused 224 00:10:47,550 --> 00:10:50,760 by misconfiguring the brightness and the contrast. 225 00:10:50,760 --> 00:10:53,760 Always remember to configure the brightness first, 226 00:10:53,760 --> 00:10:57,450 and once you've gotten to that optimal brightness level, 227 00:10:57,450 --> 00:10:59,103 then configure the contrast. 228 00:11:03,300 --> 00:11:05,580 Next, use a filter on the monitor. 229 00:11:05,580 --> 00:11:08,970 Sometimes a user will complain of eye strain. 230 00:11:08,970 --> 00:11:11,370 This might not be a video issue at all. 231 00:11:11,370 --> 00:11:14,190 It could be due to glare from fluorescent lights 232 00:11:14,190 --> 00:11:17,070 or from the sun coming through the window or whatever. 233 00:11:17,070 --> 00:11:20,070 Consider using an anti glare filter. 234 00:11:20,070 --> 00:11:22,620 And we showed some of these previously. 235 00:11:22,620 --> 00:11:25,020 Companies like 3M make these 236 00:11:25,020 --> 00:11:28,440 for specific individual models of monitors, 237 00:11:28,440 --> 00:11:30,180 and they help to reduce that glare 238 00:11:30,180 --> 00:11:32,613 from all the lights and sunlight and so on. 239 00:11:33,510 --> 00:11:35,370 In a more secure environment, 240 00:11:35,370 --> 00:11:37,890 consider also using privacy filters. 241 00:11:37,890 --> 00:11:41,250 These will reduce the viewing angle of the screen, 242 00:11:41,250 --> 00:11:42,450 and only the person sitting 243 00:11:42,450 --> 00:11:45,120 directly in front of the screen will be able to read it. 244 00:11:45,120 --> 00:11:47,943 And privacy filters often reduce glare as well. 245 00:11:52,170 --> 00:11:55,980 Next is check for newly installed applications. 246 00:11:55,980 --> 00:11:59,700 New applications could cause the display to malfunction 247 00:11:59,700 --> 00:12:01,680 or stop working altogether. 248 00:12:01,680 --> 00:12:04,890 So you wanna check the application manufacturer's website 249 00:12:04,890 --> 00:12:08,370 for any known hardware compatibility issues. 250 00:12:08,370 --> 00:12:12,390 And if you're working with powerful programs like AutoCAD 251 00:12:12,390 --> 00:12:14,820 or Adobe Premier Pro 252 00:12:14,820 --> 00:12:16,980 or a lot of the games that are out there, 253 00:12:16,980 --> 00:12:21,690 they will often have a list of recommended video cards. 254 00:12:21,690 --> 00:12:23,670 And so you wanna go with that list 255 00:12:23,670 --> 00:12:25,260 when you first build the system. 256 00:12:25,260 --> 00:12:28,200 If you're troubleshooting a system that already has a card 257 00:12:28,200 --> 00:12:30,330 and you have an issue to deal with, 258 00:12:30,330 --> 00:12:33,600 then you may need to upgrade the application, 259 00:12:33,600 --> 00:12:38,600 or you may need to upgrade the video card driver, or both, 260 00:12:38,970 --> 00:12:40,680 or in the worst case scenario, 261 00:12:40,680 --> 00:12:42,840 get a new video card in there. 262 00:12:42,840 --> 00:12:45,960 And if you do, again, check those requirements 263 00:12:45,960 --> 00:12:47,960 for the software and the recommendations 264 00:12:49,162 --> 00:12:51,993 for the video cards to choose. 265 00:12:53,460 --> 00:12:55,860 And finally, check inside the computer. 266 00:12:55,860 --> 00:12:57,570 I usually leave this for last 267 00:12:57,570 --> 00:13:00,840 because it's time consuming to open the system, 268 00:13:00,840 --> 00:13:03,390 unless I have a sneaky suspicion 269 00:13:03,390 --> 00:13:07,080 that one of the connections inside the computer is loose. 270 00:13:07,080 --> 00:13:10,530 So check whether the card is seated properly, 271 00:13:10,530 --> 00:13:15,530 and in areas where temperature and humidity changes quickly, 272 00:13:15,690 --> 00:13:18,570 you gotta watch for the card being unseated. 273 00:13:18,570 --> 00:13:22,770 And that could be due to thermal expansion and contraction, 274 00:13:22,770 --> 00:13:26,913 and some refer to this as chip creep or card creep. 275 00:13:27,840 --> 00:13:30,330 Also, if the computer was moved recently, 276 00:13:30,330 --> 00:13:32,250 the card might have gotten jostled 277 00:13:32,250 --> 00:13:34,500 and come out of the slot slightly. 278 00:13:34,500 --> 00:13:36,510 Also verify that the power connections 279 00:13:36,510 --> 00:13:38,250 and other cables are not loose. 280 00:13:38,250 --> 00:13:41,520 You wanna make sure that those internal six pin 281 00:13:41,520 --> 00:13:46,350 and eight pin PCI express connections are secure. 282 00:13:46,350 --> 00:13:49,080 And check all the other connections inside the PC also, 283 00:13:49,080 --> 00:13:50,193 just to make sure. 284 00:13:51,510 --> 00:13:53,100 For example, if the system makes use 285 00:13:53,100 --> 00:13:55,800 of an onboard video controller 286 00:13:55,800 --> 00:13:57,870 and you start seeing garbled images 287 00:13:57,870 --> 00:14:01,020 or strange colors or cursor trails, 288 00:14:01,020 --> 00:14:04,143 then you might have a defective RAM module. 289 00:14:05,040 --> 00:14:07,020 Or maybe you know, another issue. 290 00:14:07,020 --> 00:14:08,700 It could be anything hardware. 291 00:14:08,700 --> 00:14:11,130 So remember that the onboard video controllers 292 00:14:11,130 --> 00:14:14,430 rely on the sticks of RAM and the motherboard, 293 00:14:14,430 --> 00:14:16,590 as opposed to the individual video cards 294 00:14:16,590 --> 00:14:20,370 that have their own RAM and their own GPU. 295 00:14:20,370 --> 00:14:23,493 So watch for that as well, always check inside the computer. 296 00:14:24,540 --> 00:14:26,310 That's about it for the part one 297 00:14:26,310 --> 00:14:27,360 of the video troubleshooting. 298 00:14:27,360 --> 00:14:29,790 There's a lot of things that you could check, 299 00:14:29,790 --> 00:14:32,910 and some of the possible things that those might fix. 300 00:14:32,910 --> 00:14:36,240 So watch for these, and in the second section, 301 00:14:36,240 --> 00:14:39,660 in part two, we're gonna talk about some common symptoms 302 00:14:39,660 --> 00:14:42,210 that you might see, and kind of do it in reverse 303 00:14:42,210 --> 00:14:45,903 and talk about what you can do to fix those problems.
