Question about Televison & Video

1 Answer

My 3 year old Westinghouse LCD TV is now going black. I have to turn it off and back on to get the picture up. Does this mean the bulb is going? I would think that if the bulb was bad it wouldn't work at all. Dave

The lights normally last for a very long time, the manufacturers claim that the could last up to 60000 hours.
In this case It appears that it could be the inverter board from where the lights get the power from, or the +24VDC are not being supplied; if the 24VDC are not supply from the power supply the inverter board ot lights will not work.
The 12VDC that supply the audio circuitry are working, since you can still hear it.
Let me know if you need further assistance.

The picture come on then goes black and then the television turns off. I thought it might be a bulb problem (4 years old). So I bought a new bulb, seemed to work and then began to go black again with all 3...


when the colorwheels start to go bad this is the symtom that shows up. try this listen carefully to the rear of the tv near the lamp door. as you turn off the tv if you hear a slight grinding noise as the colorwheel slows down that means the bearings inside the colorwheel are dry and you will need to replace the colorwheel.

Sony Wega kdf-50E2000 Keeps turning off and on


Before you replace the lamp I recommend trying to clean/dust the lamp component and lamp plug in area. I had the same problem and was able to resolve it by simply blowing the dust off the lamp components and fan. Use a can of high pressure air to get into the cracks and crevices.

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.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
