screen goes black while playing hd videos - Nexus 7 Q&A, Help & Troubleshooting

Hi guys,
I tried searching a lot but I have not found a solution for this.
While playing HD videos the screen starts to dim and then goes completely black. The touchscreen however works even if the screen is black I touch where the back button is supposed to be and the screen come back.
This happens only while playing HD videos , SD videos work fine and all tegra games also work fine.
I have tried various custom kernels as well as custom ROMs , just not sure what could be the issue.
Thanks

problem when playing games !

hi guys i have a problem that when i play any game and touch the screen the game ran slow so i cant play the game well like COD2 (not only COD2)
the same game on Eten glofiish M700 but it play normaly very good when i touch the screen !?
ok what the problem is there any option that i can change or anything to solve this problem in my touch dual ???
i have seen the same issue, alot of games i have, not all seem to run laggy/slower when touching on the screen itself, however in some games you can map the keys to hard keys on the touch and when you play without touching the screen it runs fine. I dont know the reason...possibly just the processor speed?
edit: i had tried cod2 and deleted it right away because it was really unplayable due to game speed.

[Q] Problem when playing (youtube) videos

Hi,
I have a problem with my X5 when it plays youtube videos (in HD or not)-I have not used it to watch other videos or movies-.When I rotate its screen horizontally, half the screen becomes white or green with some red lines and the other half plays the video normally.
I have installed the latest Flash player. Is this a hardware or software problem? Is it serious? I have DOA so I can send it back and get a new one.
What should I do?
I have taken a picture of my problem however I cannot post the link here because of the xda policy
me too. found that if you don't rotate the screen until the video starts playing its fine.
Never had this problem. What ROM are you running?
In the Build Number the last digits are B135SP02. So I guess am using B135.Am I right?
Yes right. I'm using 133 and have no problems.
Mine also has this problem on several rom versions (B135, B158, B160), with or without overclock.
I am using x5. Could there be any problem with the hardware?

Browser problems on ICS?

I have seen multiple problems posted about issues with the various browsers crashing while viewing flash video and then switching to full screen mode.
I have found that ICS+ browser is the most stable. Also, I found a way to make it work 100% of the time.
The problem seems to stem from the fact that even though I have desktop mode enabled and flash set to run as "always on" this is not the case.
When you start a video you still have to "activate" flash by pressing somewhere within the video screen (I press on the slide bar) or you get a black/blank screen after switching to full screen and the browser becomes unresponsive. I have done this and videos have worked 100% of the time.
Just now I tried to play a video and forgot to activate flash on the screen and the video crashed (black/blank screen plus unresponsive browser) and I had to force a stop of the browser in the application tab under the settings menu. I then reloaded the same video, pressed on the screen (got a green flash) and switched to full screen no problem. So it seems the issue is with the flash player and not necessarily the browsers, the rom/kernal or tablet (hardware) itself. Don't know if this is just an issue with our device on ICS or if the problem exists on other devices as well.
Curious.
just thought I'd share my experience/discovery? for other to try out.

[Q] HDMI

I am curious i have a hp extreme slate 7, I plugged in the hdmi cable to watch movies on my tv and it works flawlessly however i am wondering if there is a way to shut off the tablet screen playing video while watching a movie on the tv? I thought it would be a good idea if it could do that but upon thinking about it more I dont think that it will because you have to shut down the touch screen. Please let me know if there is anything already on this subject or ideas. I have a usb keyboard and gamepads to actually navigate the websites and stuff if the screen is off just havent found anything on it yet. Thank You
There's an app called second screen which has an option to turn the backlight off, the touchscreen still works but it's a lot less distracting.

Fire HD 10 2019 Youtube screen sleep issue.

I have noticed an issue with the new 2019 Fire HD 10 tablet when using the Youtube app. While watching a video the screen randomly goes black like the screen timed out but the sound continues. Also if you use the power button to lock the screen while watching a Youtube video, the screen turns off but the sound continues. I've tried this on two different 2019 HD 10 tablets with the same result. My old Fire HD 8 2017 does not show this issue. Has anyone else noticed this issue or have a solution?
I've already contacted support about the issue with no fix. This is actually the reason I've tested it with a second device.
The screen timeout is set for 2 minutes but it randomly turns off in 2 minutes or longer, or sometimes doesn't turn off and works normally. It seems like most of the time it doesn't recognize a video is playing at some point and turns the screen off while leaving the video playing and you hear the sound.

That causing an issues from OMX codec or screen timeout. Can you enable stay awake in developer options and connect charger to work.

I'm sure I could turn screen timeout off in order to force the screen to stay on but that's not a fix. I would be more likely to damage the screen by forgetting to manually turn it off at times. Also, that wouldn't fix the issue with when I want to lock the screen using the power button and the video continues to play.

Yes it seems to not have the issue. I did have to turn background play off to avoid the power button lock, continued play. It's strange because that could be the issue with the original Youtube app but it shouldn't have background play since its not a premium account. Nor do I see an option to turn background play off in the original app if it was on, only the Pip on/off option.
The other issue is getting the Youtube Vance to show in my kids Freetime profile. I havent found a simple way besides a folder app which shows all apps.
