The inverter circuit that provides power for the set's backlight is not working properly. The LCD panel itself still works, but without the backlight you can't see the display. A replacement may be available for your set. Try a Google search for "replacement inverter" for your particular model. A good source for parts is www.shopjimmy.com.

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.

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

The picture is intermittent, stays for a long time,


is the backlight staying lit even with the picture out? I had the same problem with my Aquos LC32DA5U my backlight was always on but no picture at all, just a lit up black screen, the problem is the LCD controller, I replaced that and it's perfect now.

My TV pictures turns black afetr a few hours but I still can hear sound perfectly!!!


It sounds like your rptv lamp is going out. If this is an older DLP this is most likely the cause. You can get a replacement at www.laptopsforless.com part number BP96-00224J for $151. If the tv is still under warranty, I would have them do it, otherwise replace it yourself. If so here is a link to give you step by step instruction. Please give me a good rating. ;-)
