Question about Samsung HC-P4752W 47" Rear Projection HDTV-Ready Television
I've seen a few postings here and elsewhere on the net suggesting people replace the convergence ICs or the entire convergence module when experiencing convergence problems. I purchased a service manual for my Samsung HC-P4752W rear projection TV and it appears as though the ICs and the convergence module are 2 separate things. The convergence module appears to be a smaller metal encased board located on the main board and the 2 STK392-010 convergence ICs are pretty big with large heat sinks attached and are located on the sub board. The impression that i get from reading different posts is people are saying the convergence chips are on the convergence module and the cheaper fix is to just replace the chips and a few resistors instead of the entire module. Am i missing something? In other words, replacing the chips would have no affect on a faulty convergence module and vice-versa.
The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.

I would reccomend replacing the whole board. I tried the IC replacement, but ended up getting a DOA IC and doing a whole lot of work for nothing. Installing the entire board costs about $150, but only takes about 15 minutes. You get newer, more reliable aftermarket parts, and you don't have to spend any time meticulously soldering or chasing circuit board gremlins. after installing the board, I bought a service manual on ebay for $5 and made some slight adjustments to convergence, which took another 15 minutes, excluding the 30 minute warm up of the television. If there is a convergence problem with the board, just send it back and get another one.

Any possibility to email/ftp me the service manual? Also, do you know the part number(s) of the ICs? Why would it be bad to replace the whole board (BP95-00415C) or is that even the whoel board? Am I way off?
Thanks in advance.

The older sets had a convergence PCB (The ICs were on that board and it had a convergence module (The memory of the convergence settings are on that board, do not replace this module if at all possible). Your set has the convergence ICs on the sub PCB or the deflection board. Replace the ICs.
