Question about Projection Televisions

1 Answer

Hi, I have a SONY 51" tv KP-51HW40 with convergence problem. I would like to replace them my self. I have removed the board out so I can take the STK IC out. Can you give me some expert tips on what to do better to avoid any troublem. Also, do I need to check any burnt resistors? Or just replace the STK 1st. If its working, than don't have to worry about the resistors. Please let me know if you need any pictures. Thank you so much for your time. Sincerely Wing

Screen shakes / jumps vertically on my Sony KP-51HW40


The jitter is called a vertical sync problem. The problem is on the "A" board. It can be replaced or rebuilt but will be quite expensive to service.
