I purchased a new Lamp, but before I had time to install, the problem stopped occurring. I feel that this may be a lamp overheating problem due to dust or temperature and humidity within my house. I was going through power outages due to IKE at the time that this problem showed up. At least I have the replacement bulb to try if this problem shows up again.

The lamp is going bad. Very common for some Sony to do exactly what you are describing.

SOURCE: screen goes dark, sound goes quiet...

I have a sony KDF-E60A20 projection tv. The picture would go out for about 30 seconds and come back on. It would continue to cycle this way. The green power light would stay on and not flash. The sound would go off when the picture went out and come back on when the picture came back on. I tried taking the bottom cover off the back exposing the fan and blowed it out with a vacuum cleaner, also taking out the bulb and blowing it out. That didn't help. So I ordered a new bulb from Advancedlamps.com and that's what it was. I have now had it on and off for two days and no problems. Cost of lamp was $107.00 including shipping. Good Luck!

The set will need to be properly diagnosed to narrow down the problem. You could be looking at a bad inverter, bad CCFL lamp, fault in power supply or main board.

I had the same problem, stuck in a hotel room for 2 days. When I held down the button, next time I turned it on, I got the same prompt with using HDMI output, said yes, and screen went black. However, a screen then came up asking if I could see the image or not, but it has a 30 second time limit before it saves those setting, you have to click "No" on this screen, and it will drop the resolution to 780p instead of 1080 and it should work! Make sure you're paying attention so you don't miss the screen!

Powers on TV works for 30 - 45 minutes then the screen turns black audio still runs.


take a strong light and place it next to the screen when the problem returns. Do you see a faint image on the screen? If so, then your backlight has failed. Since it happens after that long a time, it is probably a problem with the inverter board and or power supply for the backlight. Bad lamps usually go off after a few seconds. The problem will appear sooner as time goes on.

Screen goes blank, audio still works


I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.
