Hey All,
I have had this Zenith 52" projection TV for about 7 years. Bought it brand new and have excelent luck with it. However, about 6 months ago, I started to noticed that the picture was getting blurry. When you first turn it on, it is crystal clear, but as it warms up, it slowly gets more and more blurry. Also, once it has warmed up fully, it starts to buzz. The buzz changes tune to the brightness of the picture. From what I have read, probably an AGC problem. But whats making it blurry? Please help. Thanks for your input.

open it up and see if the buzz is coming from the high volt splitter,thats probably the problem.the buzz is corona leak from cracks in the hv splitter.causes voltage problem that mess up the focus,etc.,
