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

2 Answers

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.

55 inch Sony Wega rear projection tv...only stays powered on for a few minutes then goes blank, green light steadily burns and the picture is dark. Is it overheating? What do I need to do to fix this?


If its the model indicated here or one similar(kdf-55xs955) you may be seeing a lamp that is about to fail.

A lot of these just before lamp failure will get very dark and if bad enough the set will even shut off.

The picture and sound on my 55 inch Sony disappears momentarily


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL-2200.You can find it here: http://www.discount-merchant.com/Sony-XL-2200-TV-Bare-Lamp-Bulb-p/sony_xl-2200u_a1601753a_lamp.htm?Click=48173 Have a blessed one!

Picture goes blank AND SOUND goes off together, both back on too


it can still be the lamp for some reason these sony tv's will exibit these symptoms when the lamps are getting weak. by the way when the lamp goes out the entire tv shuts off no video or audio, just to let you know.
