Re: Steve's AV56WP74 Convergence Repair - with Pics
first check for power to stk's. next look at all solder connections on board pertaining to stks. (resistors, caps, etc.). while doing this re-check your stk's solder connections. You can also check the B,G,R input to the stk's (using a scope) - should be similiar. you have the symptoms of the stk's not working.
Another idea after checking the above items and still have same problem, swap stk's and check symptoms again. If one stk's is bad - the original color should now work. I wouldn't use 160s - I only use the 150's.
