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

1 Answer

No video but there is audio after replacing bulb

I have a Sony Grand Wega 50' LCD Projection tv....it is 3-4 yrs old. I have already replaced one bulb and the same problems happened last week. I bought another bulb and replaced it. But the video is now cutting off but the sound is still there. I turn the tv off, let it rest a few minutes, turn it back on and the picture comes back, however after a few minutes the screen goes black again. It blinks a few times before it goes black. When I had the bulb replaced 2 years ago, it worked just fine but now its not staying on even after replacing it with a new bulb. I don't know what else to do. After putting so much money into this tv I would like for ti to work more than 3-4 years.

On my Sony Rear projection LCD TV, the picture just faded and disappeared. BUt the sound is still on. Does this mean that the bulb needs replacement?


Check how many times the lamp light is blinking, if it is blinking 3 times, it is time to replace the light bulb. If the stand by light is blinking 6 times its is the thermal fuse

New bulb is just fine.
3 blink shows that lamp cover after replacement of bulb in TV is not fixed properly or not seated well in its position.
Put new bulb and carefully place back lamp cover in its position because lamp cover will press tinny safety switch inside that will send signal to system control of TV that lamp is installed properly.
Turn On TV and get vivid picture of Sony.
Thanks.

I have the 50" SXRD XBR1 grand Wega; This has been a great set for 3+ yrs. A flashing red light promted me to replace my original buld (this site). I now still have a flashing red "power" light, shuts off...


Its the fan that cools the bulb. Try turning on the tv and look at the fan to the rear of the bulb. If the fan is not spinning that is your prblem. The tv has a safety switch that will cut off the tv if the bulb gets too hot. I was able to tap my fan with a pencil and get it spinning, but that is just a temperary fix. After a while, you will find the fan will stop working all together and it will need to be replaced.

Black bar along bottom of screen


Your TV is just getting "old" and there is parts that need to be replaced. The total for the parts needed would be more than what the TV is worth.
