SOURCE: red convergence wont move
Bill may you help me?
I have a Mitsubishi 45" Projection TV VS-4543.
The problem I am seeing is that there is a red gosting/double image. I found out that the coil L8W01 was burnt out and the trace pad that leads to pin1 of connector VR was also burnt on the MAIN PCB board. I had replace the coil and retrace the trace pad, also I had replace a new red convergence IC STK391-020. The problem still occure. I try to adjust the color alignment and the convergence alignment using the remote controle. The red line is not thin and sharp like the blue and green line. It is blurry and wide. Also the the red wasn't able to move in to the center of the alignment pattern when trying to adjust 5 different position during the convergence adjustment. What else can cause that problem? Please Help.

You need to replace the convergence ICs they are located on the large aluminum heat sink on the circuit board on the left. Either STK392-110 or STK392-120 are used in that chassis. And you can order them at this link and they provide free step by step instructions with pictures so you can do the repair yourself in about an hour. Heres the link. Just look for your stk numbers under the convergence IC section you will need to replace both of The ICs. If you need to know what they look like heres a pic.
