The lamp cannot be tested with a meter. The lamp is most likely your cause and should be replaced.

Tv nt coming on red light is on next to power light 50 inch lcd projection sony tv


hello. it sound's like you need to replace the lamp in your set. and here is how to do it the right way. rember to all ways unplug your set.. # 1 first. .Remove the outside lamp cover. The lamp cover is located on the right side of the Sony television. To remove the lamp cover, simply pull down. You will now have access to the lamp housing. # 2 Open the lamp housing door by turning the locking handle counterclockwise while pulling the door toward you # 3 Pull the lamp unit straight out of the television unit. Be sure not to touch the bulb, as it may still be hot. # 4 Slide the replacement bulb into the lamp housing. # 5 The lamp will slide securely into place.!!! "Do not" touch the new bulb as it will cause damage to the bulb and result in malfunction. # 6 Push the lamp door back into place. Turn the locking knob clockwise to secure the door in place.# 7 Slide the outside lamp housing cover back into place on the television.!!! plug your set back in to the wall & The television is now ready for use. thank you

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.

Nothing displays on screen


the bulb maybe burnt out, I had a similar problem only no audio. The odd thing was that the lamp light was not lit indicating the bulb was burnt.

Not sound or picture from the TV


If it has been over 2 years on this bulb, I would start there cause it will need one soon anyway.
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy. However, this is one of the model that Sony has class action lawsuits against them on because it has so many problems with the light engine. See this:
