Question about Sony KP-43HT20 43" Rear Projection HDTV-Ready Television
Hi. A friend recently gave me this TV as they know I am thinking about getting into TV repair and I really want to fix it. It powers on fine and there are a couple problems with the way the picture displays.
The first problem I need to fix is image stretching. The best way i can describe it is to say that neither the top nor bottom of the screen travel in a straight horizontal line. The top of the picture appears to be pinned fine in the corners, but curves downward toward the middle. I guess to provide some imagery as to what I mean, the picture has the appearance of a cardboard box with weight on top that begins sag in the middle. Does anyone know what the problem is or how can i fix it? How much would it cost?
I'd appreciate any help. Thanks.
Assuming that you have adjusted the convergence and this had no effect. you might have some blown convergence chips and/or resistors. these make the 3 color line up with each other.. my 55 in phillips did the same thing and the more i used it the worst it got. first it was the blue and the red and finally the green., replaced chips and resistors and the problem went away... good luck.. a lot of soldering involved. but the chips are only like 11.00 each and the resistors are like ten for all three.
