Hi,I have sony projection tv KP-57WS510 every subject apears threeple with colorful reflection.What to do? Thanks,Kris


You will have to install a convergence repair kit which will consist of both convergence ICs and the 8 associated pico fuses and the 4.7 ohm resistors will also need to be checked. Your model uses the Sony type 1 convergence kit. If you want to know where you get one they are available from www.tvrepairworld.com they do include the parts and the CD with repair instructions.

Convergence problem


Usually what happens is that the convergence IC goes bad or the fuse going to the convergence ic goes bad. Pico fuses they are called sometimes open up. You may want to open it up and pull the board out and check the solder connections on the convergence IC. Sometimes these get fractured or cold soldered and aren't making connection to the PC board.
Let me know if you feel comfortable with pulling TV chassis out or pulling the board that has the convergence IC on it out. Then you can resolder convergence IC OR replace it.First thing i would do is check to make sure there is between 22vdc and 25vdc on the fuse or the convergence IC. Let me know if this helps out any.... Sincerely HDTV GURU JAY
