When it rains it pours… A few weeks after having our 36 inch Sony CRT TV refuse to power on (we’ve since decided to replace it), we’re having discoloration issues with our 46 inch Sony LCD rear projection TV.
In terms of symptoms, the top inch inch or so of the screen is discolored with a yellow/red/pink tint. While we’re overdue for a bulb change, I don’t think that’s the band of discoloration here. Rather, it seems that the optical block is going bad.
The good news is that Sony has extended the warranty on this issue through June 20, 2010. The extended warranty covers both parts and labor, so we should be able to get the optical block replaced for free.
For reference, our TV is a Sony model KDF-46E2000. We also have a 42 inch Sony LCD rear projection TV (model KDF-E42A10) in the house. While ours hasn’t had any problems (yet), this model is apparently part of a class action lawsuit.
