One of the power supply areas are most likely going intermittent. This can be from cold solder connections on the circuit boards, or from some components failing due to age.

An experienced tech should be able to service your set, but it will be expensive for the time involved. Sometimes these types of faults can be very time consuming to resolve.

Sounds like you have some solder problems on your deflection board. If you're up for it, you could fix that yourself with some solder and a soldering iron. Just take the back off, and look for the board with 2 of these on it (numbers may be different).

Remove the board carefully noting where you unpug things (take photos if needed). Then reflow the solder joints on these parts. I hope this was of assistance, best wishes.

I may be late with this but it souonds once again ike dust in and on the bulb cage. These TV's will turn off by themselves if they over heat. The extra dust(not much) can/will cause the TV to heat up and shutdown for a few seconds to a minute. Depending on the time of year and location of the TV can vary.

Try removing the bulb and cleaning it with compressed air and a micr fiber towel. Of course don't touch the blub itself as the skin oils will cause it to break.

Hi, My 60 inch Sony projection model # KDF-E60A20. Purchased March of '06. About 1 year and a half ago she started giving me problems. Every 30 secs or so tv would go "black" and no sound for about 30 secs...


This could be caused by dust on the bulb. Dust can cause the unit to over heat and will shutdown for a few seconds to a minute and then come back on when it has cooled down. This time can vary depending on the location of the unit and the temputure in the house. The dust becomes hot and so the Thermal unit shutsdown for a short while and then comes back on.

Clean the bulb by removing the cage and using compressed air and a micro fiber towel and install back intot he unit. Make sure you follow the Sony Maunal. Also make sure not to touch the bulb as the oils from your skin will cause it to burn out quickly.

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.

Pic freezes, goes dark w/sound then back on


By what you have said your color wheel can cause this when it stops running .Pull back off and watch what is happening when you turn set on.
