It seems that your T-Con Board is not Working. It is located inside top/back part of the Panel. Try to replace it with the original Part number. Hope this helps your TV. Thanks

Dynex PO2-w30-003s no picture sound ok


put a flashlight behind the TV screen or front screen close, just try as close as possible, if you see image that means that the Back-Light inverte is defective or the screen lamps are not working, if deres no imagen the video card is not working (main board)

Black screen with sound


My 47" LCD Smart T.V. was working fine last night. I got up this morning and I have sound but no picture. The VIZIO icon lights up as usual but I get no picture, only sound. From the time I turned it on, nothing appeared on the screen. I have already tried unplugging it for a while and still nothing.

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!

Hi,
It seems back light inverter board is not producing voltages to lit the back light inside lcd panel to show the picture on lcd screen.
Please replace back light inverter board to get tv fixed. Local tech will help you if you are not familiar with tv repair.
Thanks.

No picture Just Sound


Hi
There are different possibilities in your case¸but what happened to me ...
The LCD Backligh is out , I mean the bulbs or neons of the screen BACKLIGH, you have to check either the lights itself or the driver circuit which supply the HV to operate it, usually its a separate small long PCB beside the TV main board .
You can try this trick , Keep all lights off in the room and bring a table lamp, preferred a white neon one and face it lighted on the top of the screen with the TV on , try watch a very dark but exact picture with the sound you are hearing. This is a way to be sure that it is LCD backlights problem when using an external light to illuminate the screen .
It worked for me ,Good luck
