I have a samsung rear projection tv model #hc-p4752w tv. In the convergence mode I cannot get the blue to move up and down.This is my first rear projection tv. So I am learning as I go.Plus the picture is curving inward at the top and the botttom. Can anyone please help.
You will need to change the convergence IC's or the convergence driver board. If you do not have any experience with solid state repairs, it would be best to have an authorized Samsung repair shop do this repair for you. It should run you about 300 bucks to do this repair. Good Luck
Would I have to make any other adjustments after replacing the IC s or the driver board? Would you konow the part number or the price of the driver board?
Yes Sanyo made convergence/IC chips for most if not all the major bread rear projection TV's making them the OEM. If you are looking for OEM chips or convergence repair kits you can find them for most major brand TV's at www.tvrepairkits.com.
