    I have a Samsung HC-P4752W Rear projection TV, and I'm haing a convergence problem on the right side of the screen only.the red is almost 1/2" higher than the rest of the colors on the right side. Is this something that can be adjusted, or do I need to do an IC replacement? What are the part numbers I would need?

This is a problem with the convergence circuit. If you can solder, you can fix this yourself. First try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. FIgure on $25 each for the ICs.

    Schematics should not be requied for this effort. Post the exact STK and I'll give you the pins that would heva either the fuses or low values resistors. Either component will be marked so replacing them should be relatively easy. Make sure that you use plenty of heat sink compound between the STKs and the heat sink too.

Hello, I have a 60" Phillips rear projection TV


It sounds like a convergence problem; depending on your skills it may or may not be something you can do (parts cost on EBAY will be under twenty dollars).

I will attach some convergence photos: does your set look anything like these?

If it does and you can solder etc I can tell you the best place to get the parts and how to do it.

Before you rate this information let me know what you find.
