2001 Sony KP-53V90 53 in. Rear Projection Television has a problem related only to the picture, the top and bottom of the screen are bowed into the middle, the video feed label and volume scale are also bowed. The screen also has 3 RGB lines crossing the top of the screen.

Replace TDA6120Q on the blue CRT board.

component failure on the convergence board - expect to pay a bit for this repair - not cheap

change convergence ic.

the sony service menu can be entered by pressing "display" "5" "vol+" also the diagnostic screen can be reached by vol- instead of + when you are in the service menu the number buttons navigate it its a little tricky at first but as long as you dont hit enter before you exit if you mess up it wont save just make sure if you fix it you save it by pressing enter

If the picture is bowing in on the sides, this is called a pincushion problem. Please confirm that your model is KP-53XBR45 and I'll look up the probable defective parts.

Are the convergence controls also out of adjustment? Please respond to this same post and I will help you. If you could post a picture of what the screen looks like that would even be better.

Have your convergence amps replaced ....by tech and all will be good.

You need to have the convergence IC's replaced. A repair like this should run you about 300 bucks or so. In most places.

look in hte convergence circuit for opened reistors.

you have a convergence problem.. If you understand how this works then you can go into the set find the convergence ic's and replace them and sometimes you need to do some alighnment as well. Its always best though to let a service tech do a job like this as he will have all the proper equipment to adjust and troubleshoot the set Good luck
