If u have sound, hold a flashlight to the screen and look for a picture. if u see a pic, the backlight/inverter has failed.

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 Vizio LCD TV screen fades to dark. Sound stays on.


I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.

Black screen only on new LCD


Sounds like the video board when bad. I would say the TV went defective. Use the 90 day warranty to exchange for a new one.
Always use warranty at this point because the newer TV coming out in these days have very lame warranty.

Rate me, please

Philips 32 LCD TV 32PF9541 Black Screen


Sounds like a temperature problem if it takes a while for the problem to happen there are several things u can try and figure it out yourself. 1. Remove the back cover of the tv and turn the tv on. 2. use a hair dryer and apply heat to various boards of the lcd (inverters, power supply and scaler) while applying heat to see what board reacts and makes the tv go dark. More than likely its a defective LCD panel and its just as easy to send it back and get a replacement TV.
