Screen picture constantly goes black then comes back every 3 seconds. Sound stays. Television is 3 years old. Not sure if this is the model.

sounds like back light invertors or worse the panel is defective

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!

Capacitors on the power pack are going bad they need to be replaced that should fix the problem.

I have a 40 but i was having the same problem. It turned out to be my lamp. I got a brand new lamp from Projector Lamp Services (relampit.com) and my tv works fine now. Im pretty sure that the 40 and the 60 take the same lamp. You might want to give them a call.

All symptoms in your TV shows that you need to replace its Lamp as it has been consumed its life hours and TV requires new lamp. Lamp can be obtained from Sony Website. Price is $200, Hope this info will help you to enjoy your Sony TV in coming days.

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.

I have the same problem. The next stage is that the picture won't come on at all and the blue light will constantly blink. I think the light source is bad. Noit sure though.

Try resoldering the vertical output IC this is acommon problem with this model

tbrace, your picture tube is getting a little tired, the "IK circuit" is causing the blanking of the video because the tube is not returning a large enough signal back to the IC that monitors it. Theres only one fix (besides replacing the tube) for your set and that is to turn up the screen control. You have to remove the back from the set and on the right hand side there is a large plastic part called a flyback transformer, with a heavy wire coming out of the top which goes up to the picture tube, mounted on the front of this transformer is 2 black blastic "philips type" controls, one over the other look closely and one will be marked focus(do not turn that one) and the other is the screen control, turn the set on and SLOWLY turn the control clockwise until you see a bright picture with white lines in it, once you see the lines turn it back until they disappear, (check several channels to be sure they are gone) your done, may last 3 weeks, may last a year, it`s all you can do, BMW Rider

I do not see any reference on this problem and I even checked with Sony. If you are on a cable box, I suspect that is the problem.
