    I have the same problem since the day we bought it. The picture was awesome in the store. After it was delivered to our home it was like a different tv. It's so dark you can barely see and the color is so dull. Don't know if we should spend the money on a bulb or not

The problem might be with the circuitry driving the LCD screen. Since the back lighting blub has been changed the only thing that could cause this issue would be the screen brightness which is controlled by the LCD circuitry. You will need the schematic to aid you in the measuring of these voltage values.

Sony Grand WEGA KF60WE610 - Over the past 6 months, bright points of light have developed on the screen which are always there, but are noticeable when the the background is dark.. Is there anything I can...

If they look white or like pixels out this model is prone to a bad optical light engine---it is the heart of the set and most expensive part as well--typically it starts with one or two and over time more "appear".

Brightness problems with sony kf-50we610

This is typical for a set that uses a lamp, as the lamp needs to warm up.

If it is taking longer than normal to brighten up, then your lamp could just be aging and needs replaced.

I have a sony kf-60we610 2004 and the bulb is good, but the tv doesn't stay as bright as it use to and I have the brightness max out. any ideas?

IF the lamp has been in the set for a while it may be your problem---some of these sets before the lamp fails the picture will get darker--lamp will look ok but can cause this trouble.

If you replaced it at some time with a "Generic" replacement other than an Original Sony--that can also be the trouble.

Lamp life is about 2,000 hours and time can pass quickly.

Let me know if I can help--I am here to help.

I have a Sony Grand WEGA KF60WE610 and i get green lines or dark lines running across the screen, they are horizontal lines. I have had the bulb replaced and it hasnt changed. Any ideas?

It sounds like you possibly have a bad optics block. If thats the case it is not a user replaceable part due to the tear down to get to it. Is there anyway you can email me a picture of the television with the symptom and I can possibly help from there? My email address is tvtek(at)
