Question about Televison & Video

My LCD flat screen just goes black after 1 hour of being on. Checked the cable. Changed channels. Turned it off and then on. Only will come back on after it is turned off for at least 15 minutes. Sound is still on when this happens.

How do I fix a black screen with sound working and LED light on.


Unplug the set and let it stand for two minutes. Plug it back in and see if it works. If that doesn't work contact Philips support: http://www.support.philips.com/support/contact/contact_page.jsp?userCountry=us&userLanguage=en

My vizio is blinking back and forth from the blue no signal screen to the actual hdmi input screen which is connected to a cable box. What is going on?


Have you tried a different HDMI input? (If available.) You may be able to test the cable box of PS4 using component cables to confirm that all but the HDMI is not working. You may try pushing or holding the HDMI cables to see if you can make the problem better or worse to identify a possible flakey HDMI socket.

LG M227WDP turns black a couple of seconds


Do you have the "sleep" mode turned off on the computer?
As well, you can try different screen resolutions and refresh rate settings on the video section of your computer. That might make the connection to the TV more stable.

Sound stays on, but no picture- goes black and stays that way.


This unit should still be under warranty and should be taken in for warranty service. Any attempt to access the interior will void the warranty. It is important that a complete description of the problem like you entered here be taken along when you bring the set in for service. This will insure that the servicer be able to reproduce the problem and resolve it.

From your description (and as a servicer), I would be looking for a component that is heat sensitive. These types of problems are fairly easy to locate and resolve.

Please take this in for warranty service and update this when you find out the details.

Thanks,
Dan

My samsung TV won't show any picture/sound.


When the TV is on, need to check the back light is on(go back side & look into through)

If the back light is on -- need to exchange the Main Board
no back light -- exchange the Power Board --- 95%
exchange the LCD panel --- 5%(inverter)
