I have a Zenith Z25A66R went from working fine to it wont turn on. I hear the same noise coming from the Tv when i try to turn it on as it has always made but there is no picture or sound, but power is there. I havent taken the back off yet , dont know what to look for but there is a smell when its power on. In the last month add comcast digital box but it worked fine until yesterday.

I do have the same problem on my ILO 26HD It worked fine for about a year and sudenly it got freezed, can anyone please find what it is?? Thanks!!

The ILO is less than then a year old and the sound will not ajust nor will the remote work. I tried the buttons on the side and they will not work either. What to do?

SOURCE: sound but no picture

check with a flashlight against the screen for picture, if present backlight inverter has failed.

SOURCE: My Sharp TV will only hear sound. No picture or images even from the tv menu setup option. Model# LC-19SB25U. About 1.5 yrs old. Converter box ok.

In most cases, you can reset the TV by leaving it unplugged for 30mins.
If this doesn't work, I believe the circuit board that supplies power to the screen maybe bad. They call this board a backlight inverter board. It would most likely cost more to repair than replace the TV .

If the fuse burned out the the tv would not turn on at all. When the tv is on is the back light still on? If its not its probably the back light that needs changing. If its on then its one of the circuit boards.
