Question about Televison & Video
I have a 60'' pioneer projection and the blue color is off like a good 5'' from the center of the TV.
is there a way to fix this or do i need to buy something?
ive heard something about IC's... what are they exactly, i am electronically savvy just never worked with Tv's before. anyone wanna fill me in on what an IC is and does. and what the part number i need would be so i can replace both of mine. and whatever else may need/ want to get replaced at the same time

The converence IC's are the problem. Unfortunaely, I do not a service manual for that unit. You will find the IC's mounted on a large heat sink. The nuers usually start with STK-xxxx. Find these IC's and copy the number off them. Usually the can be replaced by generics. You can order them directly from Mat Electronics 1-800-628-1118. Be extremely careful when you desolder these ICS the foils are easy to lift. Use desoldering braid(chemtronics) 10-25L. Also ask for BOB and tell him that Tom from TOM's Tv suggested him. This will insure you the lowest price. Also some times the current limiting resistors open up. Always replace both convergence ICS. In your case only one is bad. Replace both anyway. (they only cost about $12.00 @ Any further questions, contact me. These are great TV's and well worth repairing!!! Scrivitron

Before you go and buy parts it might be worth your time to check the convergence power supply fuse. It's located in the back of the TV just to the right of a large black component with 2 red wires coming off of the top. This is the flyback transformer. Just to the right of the flyback you should see three fuseable links that look like chicklet's gum. The one that may have fried is the one in the middle, it's a 400mA 125V fuseable link. Hopefully thats all your problem is.

I have the same issue, on my 60pp9202. It works some times, and then its ok. If I leave it on, it will be ok, until it gets turned off.
