    My Sony KDF E55A20 is going off every minute or so (completely blak and no audio) then comes back on slowly after almost 30 seconds. I have had the TV for 3 and a half years with no problems. There are not lights blinking for me either. Anyone find out what the problem is yet?

    Same problem, same unit and similar age.
    I am also not seeing any visual clue on the front panel to suggest a faulty bulb, as the manual suggests.

    The sound also goes away, which makes me question the bulb as the culprit ( why would the sound mute if the bulb is intermittent??)

Follow up: The audio/video blackouts were in fact a precursor to the bulb going bad ( even though no lights on front indicated such as the manual suggests). Replaced it, blackouts went away. Picture is noticeably brighter, so the bulb was showing signs that I didn't pick up on. If you're reasonalby handy, the lamp assembly is an easy fix for approx $200-$250 .

Replace sony projection bulb, tv has delay with picture coming on


I would recommend taking your tv to a tech. You don't want to risk breaking something else in your tv over a simple issue.

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!!!

My sony kdf e55a20 cuts on and off, but the lamp indicator never turns on


Order a new bulb, easy to replace, just read the manual. In the meantime, go into Settings and change the Power to Power Saving, instead of Standard. Your bulb will work fine until the new one arrives.

TV goes off about every 45 seconds - comes back on picture first


The repair man just left my house for the EXACT same problem on the EXACT same model TV. All he had to do was remove the front panel on the TV and clean the bulb and fan. He said the bulb may have to be replaced before long but it is working perfectly now!! $100 service call to clean the bulb!

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!

Kdf-e55a20


In my experience with these models, if have found that your fault could be due to a blown bulb assembly. This can easily be checked by looking up the bulb replacement procedure in the user manual. The bulb should look clear and see-through to the tip of the filament. There must be a small class pipe inside which has a wire connected to the tip.

Any white residue or black discoloration inside the bulb indicates a blown bulb. You can contact your nearest Sony service centre for a new replacement bulb. Write down the "XL-xxxx " number as you will have much faster result than giving the model number.

If you need any more assistance please post a reply.

Best of luck.

I finally wet out and bought the tv repair manual. Thought the problem had to be more than the bulb because i was losing sound too. Everything in hte repair manual brought me to the bulb or the ballast. I ordered a replacemant bulb. I spent about 150, which included overnight shipping. I replaced the bulb just before Thanksgiving and haven't had any problems as of yet....
