Picture goes black after a minute or so...

I have a picture when I first turn the TV on, but it goes black after a minute or so. If I shine a flashlight on the screen, I can see the images.

Replaced the 4 power capacitors now tv runs for 15min. then picture turns black and volume stays on

when the picture goes black, dim the light in the room and shine a bright flashlight on the screen. If you see a faint picture, you have a backlight problem. If this issue came about after you installed the capacitors, double check the installation of your caps. Ensure that you don't have cold solder joints or broken joints!

I turn my tv on the picture and sound all work and after about 20min the picture goes to a black screen and I still have my sound. I turned the tv off wait about 5 min turn it back on the picture come on...

If you have electronics experience - check the power supply and make sure you are getting the correct voltage to your inverter boards and main av board - also do you see any movement on the screen take a flashlight and shine on the screen - if you can see a dark image on the screen check inverter boards and power first.

thanks,

michael

Picture works for a while than goes out, but the sounds stay on. I turn the TV off wait a minute, turn on, picture works than goes out again ??

It sounds to me like you either have a bad inverter board(The board that lights up the screen),or a bad bulb in the screen itself.When you turn it on,and the screen goes away,shine a light on the screen,and see if you can see a picture.I hope this helps.Thank You very much!

Dynex 32" tv picture goes black

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.

If this is the case..you have the above problem!
