Question about Sony KDF-E55A20 55 in. LCD Television

Sony KDF-E55A20 No picture or sound

I was watching a movie one night when the screen suddenly went blank and the sound also was gone. I thought one of my kids turned the power off, but when I tried to turn the power back on I noticed the power light blinking red. I can't turn the power off with the remote or on the tv, I have to pull the power cord out of the wall. there was no "popping" noise like the manual says can happen when the bulb goes out. I've contacted a sony style tech and he said it is a "circuit failure." From what i've read about other peoples problems it sounds to me like the thermal fuse. What do you think?

Re: Sony KDF-E55A20 No picture or sound

The little flashing light down on front of your TV will tell you the problem by the color of the light or the blinking intervals, this is the reason you can not turn it off is telling you something. The manual should have a section dedicated to this part, most likely is the bulb, the bulb is easy to access generally hold by one or tow screws you can pull it out to verify the integrity of the bulb. Then again check the LED light before anything then you go from there.

Hi This is most likely the inverter panel that drive the CCFL's (Backlight tubes) or the backlight tubes themselves, I'm afraid I can't help with the diagnostic test or service menu.

While watching TV we got sound and the TV stoped working.. No picture.. when we turn on it makes noise..but no picture..what could be the problem.. Do you the lamp is gone.. or some other problem..

IT may because of over heating and more alternate current.....the picture tube is gone away from which video is not seen and speakers are tered due to high volume it seems so but do take that channel you are watching is consists of a channel.....otherwise without channel it ll make sound possibly......

Sony Bravia - no picture, no sound. Just a blank screen. We were watching a show and the screen went blank and no sound.

First thing to try: unplug from the wall; count to ten; plug back in; try again

Second thing to try: unplug from the wall; count to 10,000 (or wait 10 minutes or so); plug back in; try again

#1 worked for me when it would power on with no video, no sound, just small green light + white logo

Picture goes out, comes back, sound is fine

I found several instances of this probllen on various forums, and determined that it is the bulb after all. It seemed that a bulb should either work fine or be burnt out, so I thought it might be something else, but so many other customers had this identical problem that I am 99% sure it is the bulb. I found a replacement bulb with housing for about half the price of the Sony Store, so i ordered it. In the meantime, another customer offered a suggestion to try adjusting the Power setting to Power Saving instead of Standard. I tried this last night and the picture worked fine! I will replace the bulb when it arrives and keep the old one on hand in case this happens in the future. Thanks to all of the posters out there!!!

Screen became dim over time and then blank. Red LED lights blinks when on and sound is fine. Is this the bulb, unlike the others that went suddenly?

There is more than one flourescent tube in your TV, It could be possible that one after the other has failed, these should usually last a few years depending on usage.

If it is not the tubes then there may be a fault in the backlight inverter although this would more likely show up as a sudden failure.

How old is your TV?
