Question about Sony KP-53XBR45 53" Rear Projection Television
I have a sony tv bought from somebody had really great picture one day all of a sudden we tried to turn it on and it will not go on, you would hear it power click like it was turning on the red light would blink but turn right off, and I read one of the solutions they had the check and clean all the connnectors and the tv is still doing the same, Does anybody know what the problem is and is it worth fixing,
I had a similar problem. Look for a burned/shorted out capacitor on the main board. (It is marked J-something I forgot), 10mm diameter ceramic capacitor, 1000pF 20k SON116175400
It is about 3-4" from the left edge of the main board (power supply side), near the middle of the board. It is close to a large transistor mounted vertically on a cooling plate. It is a special high-voltage capacitor, you can find it online. Check the large transistor - it may be damaged too (mine was ok). After installing the new capacitor I got good sound and really weak picture. I called a repair guy who found a bad chip - after 3 hours of looking. The TV works fine ever since. As I learned, in most cases all you need is a new $5 capacitor. If you had a good picture before, it is worth the "investment" to fix this problem.
