Sony KDS-55A3000 possible Ballast Issue
I hope this is the correct forum.
I have a Sony KDS-55A3000 projection TV. A few months ago, the picture was getting darker as if the lamp was going bad. I have replaced the lamp a number of times in the past so I was aware what a failing lamp looked like. However, the lamp was only a month old and it was an OEM lamp, not a knockoff.
I called the place where I bought the lamp and they allowed me to return it and they sent me a replacement lamp, again, an OEM. The picture was just as dark as it was with the lamp just replaced.
I again spoke to the owner of the lamp supplier and he assured me that they tested the lamp I returned and it was like new. He did tell me that it was likely that my ballast was going bad.
So I spoke to a local TV repair shop and was told that a ballast does not "go bad" but that it either works or fails. He said that it was likely the optical block which would cost about $2,000 to replace!
After doing some research, I doubt that it is the optical block because other than a dark picture, there is nothing else wrong. Colors are fine, no distortion and nothing is skewed.
So to my question, is it possible that my ballast is going bad? Has anyone experienced this issue?
Thanks in advance,
