SOURCE: wega KDF-50WE655 has purple spots, support says wega engine bad

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described sounds like one of the circuit boards that control the picture quality needs to be replaced. The cost of the board would likely be in excess of $200. There are usually several boards in a TV like that that control the picture and when one goes, you can get anything from lines in the picture to poor picture quality from blurriness. The main question is do you want to spend $1000 to fix a used TV?

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

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.

Tv not working


Bulb may be bad or the lamp housing is damaged from heat. The plastic housing warps causing the micro switch that tells the tv the bulb is in goes out of alignment and the tv thinks the bulb has been removed

The red lamp light comes on and the tv does not start


Possible bad bulb or bad lamp housing. These tvs have lots of heat near the lamp and the micro switch that tells the tv the bulb is in may not be making contact anymore from warpage in the plastic surround

No picture and buzzing sound on Sony XBR Wega


Is the bulb light flashing ? - Sony's bulb light is very accurate in telling you if the bulb is bad. The buzzing sound could be from the balist trying to strike the lamp. You also may want to open the lamp door and see if the bulb is shattered.

Dark picture on wega lcd


Yes, if this TV has a bulb it is likely to be the bulb.

I am not familiar with this exact model, but other LCD Projection TV will show dim picture after some time. Expected life of the lamps is about 2yrs. After 2yrs the picture will become dim. After 5yrs I am suprised it is even working.

Dirt doesn't cause this problem unless your are a smoker or have the unit "literally" outside. DO NOT try to clean it or let someone tell you to do it because it will cause more problems than it fixes.

Sony WEGA Large Projection TV


I sounds like the projection bulb has failed. I think there is a red lamp on the front that lights up when the bulb fails however.
This sounds very similiar to what mine did when the bulb failed about 2 months ago. Once the buld fails the TV will shut itself down and keep doing that until the bulb is replaced.
