Have a Sony KP53S65 Rear Projection TV... while watching, it made a pop sound... the picture shrank (faded) to a small circle of color in the middle of the screen and than disappeared to nothing. There is no picture and no sound. The standby light on the front does come on and it just blinks continuously. The tv has been unplugged for months... after plugging it back in on a few occasions, the results are the same. Trying to diagnose and to determine if it's worth trying to fix. The tv is in new looking condition... I like it and, if possible, would rather not replace it and my entire entertainment center right now. Thank you kindly for any insight you can offer.
