Re: projection lamp shuting down

I experienced a similar problem with my Sony KDFE60A20, the projection bulb would turn off for about 90 seconds and come back on for the same amount of time then cycle off and on for about half an hour. I cleaned the circulation fan in the rear turned the tv back on and it was ok for the rest of the day. It started all over again the next day so I then took a look at the bulb, I found that the bulb has a venting/cooling screen at the top and bottom of the lamp holder, the top screen was plugged with dust, cleaned it and put it back together and the problem has been resolved now for 1 week. Seems like the problem has been resolved. Tv is exactly 18 months old and is connected through an APC UPS Backup.

Re: projection lamp shuting down

I had this problem and ordered a new replacement XL2200 lamp from Sony and that fixed it. By the way, the lamp installs from the front so there's no need to pull your TV out from the wall. Look at you manual, it is accurate in this respect. My lamp only lasted about 15 months. It costs $200 plus about $16 to ship. You can order direct from Sony on line service.

Re: projection lamp shuting down

Confirm if this is happening during explosions screenshots or high white tones images. I noticed that my set goes black immediately after an explosion or during commercials (Essurance commercials for example). I'll have a technician tomorrow to replace the power board (another problem), but I'll also show him my observations to get his feedback about the blank screen...will let u know!!!

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!!!

TV shuts down periodically for short periods of time

there is too much dust on the bulb. Take off the back panel and spray some compressed air over the bulb and clean out the fan. The dust is burning on the lamp which is causing the safety switch or breaker to shut down the bulb. I cleaned mine today and it works like new. Give it a try and let me know

Bulb went out

This maybe a McGuyver thing. Last thing you want to do is block the air flow to cool down your TV set. I would blow out all the dust, get a HEPA filter for house ventilation, get a computer cooling fan. Cut and put the filter in front of the fan, make the fan blow in to the TV vent in the back, that way it blows clean air in and keeps dirty air out. I hope that's one good idea.

Sony 60' projection model # kdfe60a20, the picture keeps going out and then back on.

Try taking off the back pannel and spray compressed air on the fand and lamp. There is probably too much dust in the fan and on the lamp, triggering a sensor to go off and you loose your picture. If the sound goes off too, then it my be something more techmical. My tv had the same problem. This is how I fixed it. You can also try replacing the bulb. They are at least half price on the internet than they are if you buy them at a local retailer.

Sony 60' projection model # kdfe60a20

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....

Screen going black Sony KDF-E60A20

Remove the lower front panel by removing the 2 large round screw heads at the lower back corners, one on each side. Remove the retaining screw on the right side of the metal horizontal retaining strip in front of the bulb holder, remove bulb retaining screw in the upper left corner of the bulb holder. Pull the bulb holder out towards you and check for dust build up on the top screen on the bulb casing, if there is an abundance of dust it will restrict the airflow across the face of the bulb which causes it to heat up and turn off. Once the dust has been cleaned your bulb should now work as it should without a problem.
