Sony 55" rear projection tv

I have a Sony KDF 55WF655 rear projection tv and it turns off for a few seconds, the green light blinks and then it turns back on and it just keeps doing it over and over.

    Sony Grand WEGA Big Screen I bought this brand new 3 years ago and have one problem other than the current one where it turns on but says "no signal to be found" and starts blinking green stand by light and then the picture and sound will come on and off intermitently as well and it continues to do this. The cable guy came out today and changed out the cable box but it still does this. Is it the light bulb inside the casing or what? I don't think it's still under warranty.

    We have the same television with EXACTLY the same problem. It started this morning. Have you found a soultion???

    This Sony has been a nightmare. We had it one year and had to replace the lamp. One month ago we got the blue dots and blue haze at the bottom of the screen. And now this!

    I have the exact same problem. Mine is a Sony 55in HDTV SXRD LCD projected TV. The Lamp will go off and then come back in a cyclical timeframe. However, after I leave it on for days, it eventually will stay on. So I simply haven't turned it off, except put it on a non-video input. I have reviewed the manual and troubleshooting manual which I purchased off the internet. I have not pulled the back off to take readings as the optical block has a 24 month warranty and it might possibly be that. But I would like to know if someone else got theirs fixed, what they had to do to it.

    We have the same problem however is is intermitent. The TV will work for hours or a full day. The next day it will start going off and on as soon as it is turned on. If it was a temperature problem I would think that it would have to be on for a while. The green power light blinks the entire time the sound and picture are off. It goes to steady green when working properly. I have service coming in tomorrow however I am willing to bet it works fine when they are here and they do not fix the problem.

My Sony also flashed the green light and intermittently went out. The bulb was loose. Once I tightened it in with the allen wrench, it worked properly

That is totally the bulb, There was a recall on that model number and I called Sony about it. They scheduled a technician who replaced the bulb and did some software upgrade. My TV works perfectly!

Try cleaning the air filter sounds like a thermal problem often cleaning the filter takes care of it.

SOURCE: Sony KDF 55WF655 rear Project tv Power/standby light flashing

This would be an error code indicating a problem.  You didn't mention if anything else was going on with the TV as in no picture, or no sound.  If the TV is operating just fine, there could be a bug in the software causing this.  If there is a problem, the best thing would be to contact Sony and relay that error message and go from there.
