Question about Sony Grand WEGA KDF-55XS955 55" Rear Projection HDTV

Picture & sound go on & off every sec, red light blinks 5 times

I have a Sony Wega rear projection 55 inch LCD HDTV. The TV turns on and there is picture and sound for about 30 seconds, then the screen goes blank (no picture or sound) and then comes back on about 30 seconds later, then repeats over and over. The green power light stays on the entire time (even when no sound or picture). If I power off the TV during the period where the screen is blank and no sound and then power it back on, there is a red blinking light where the power light is. It blinks 5 times, pauses, and then repeats. I am then able to turn the TV back on, but the same thing recurs: picture and sound for 30 seconds, then I lose both for 30 seconds, then they come back, etc.

HelloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

3 times red light blink indicates that lamp cover is not fixed properly. This can happen if you took out lamp from tv or replaced it. Lamp cover is plastic cover that need to be removed from tv cabinet to access lto lamp.
Make sure lamp cover is back in its position securely and turn tv On.
Thanks.

Picture will come on and then go off after a couple minutes

This usually means the Lamp is failing. Replacing the Lamp usually fixes it. I would only use a Sony Replacement.
You can order one from Sony at 1800-222-SONY or you may be able to pick one up from a local Sony Retailer.

Reset lamp hours on sony grand wega

hello

Press "Display" on the remote, followed by the 5 button, then the sound up key, and "Power On." Do this while the TV is in Standby mode.
Step 2 Then press "Jump" 3 times to enter the DE Service menu. The TV screen will display the total lamp time hours.
Step 3 Reset the lamp time by pressing channel 3, then mute, then enter. This will put your lamp counter back to 0.good luck

Sony wega kp51 turns on for 3 secs than off w/ blinking red light

The flashes are fault codes. It means your system is faulty. If it is intermittent then it is more than likely a dust issue. Buy an air duster, spray out the back and restart. Should be fine

If it continues to play up then it will be a repair job

Sony LCD television will not power on.

I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
