I have had the same problem with my Sony KP-51HW40 as everybody else seems to have had. The tv starts to flash a red light and then shuts off. We purchased around 3years and now its just sitting there doing nothing is it worth to fix it.

Sony support SUCKS. I called Sony and spoke with customer service from Ft. Myers FL and explained my problem in that the product was defective. Also asked to speak with a manager and was told NO. Asked for corporate address, they said NO. I asked them for their address they said NO. Now keep in mind this is SONY we're talking about. Since they were stonewalling me I asked when I should expect a response from Sony. He said that they'll review my file and should call me back. SHOULD!

Right now majority for my electronics in my house are Sony, but I'll never buy Sony again.

Loved this Sony KP51HW40 Rear Projection Television, but...
After 2 years where we watch CNN about a third of the time, the little CNN logo in the lower left is noticably burned into the screen. (Visible when any bright solid colour occupies that area of the screen.)
You would think that "burn" would not be a problem in the 21st century, but it is. No more CNN, and I won't buy a Sony next time...
