Question about Samsung HCM4215W 42" Rear Projection Television
I checked all of the connections and they're all tight. What the problem originally was that the convergence wouldn't stay and the blue would always be off to some degree. But then a couple weeks ago the blue freaked out completely and on the left it's like there is a zig zag of blue down the middle of the screen and the left side has a bulge of blue/yellow. I can't adjust the convergence to resolve it at all. I'm wondering if it might be a the blue bulb now. Any ideas?
The problem is not with the convergence board. Its the Convergence ICs which are located on the sub board. Use two stk392-040 ICs as your model probably has the 392-010 now. But you can get two new replacement ICs at the following link and they will provide free instalation instructions with pictures so you can do the repair yourself. Heres the link you will need two STK392-040 Convergence ICs.
