Question about Samsung HCM653W 65" Rear Projection Television

2 Answers

RGB COLOR PROBLEM.

I have a above Samsung TV (HCM653W). RGB color not right. Ghost the image. I replaced the AssyPCB,SUB,PCL54R,P54A but no solutions. Which pcb board I should try to fix the problem. There are audio and video on the tv, but not right not pleasure viewable pictures. Please advise me If you have any idea.
Thanks for your time.
Nicky Patel My convergence is off, the red will align but the blue won't. And at the tope of my screen and the sides it's kinda bowed a little, so that when I align the red in the center of the screen the top and the sides are still off. The repair tech said it would be a $600 part threw him. I've been looking online and I see convergence modules for $60-$70. What should I be looking for to replace it. I definately don't want to spend $600 to fix it!

    Heres a guide on the Convergence IC fix http://cmpalmer.blogspot.com/2006/11/fix... That was very helpful to build up my confidence in doing this myself. But I am at a delima now, that was for a Panasonic TV and mine is a Samsung HCM653W, so now all I need to know is...What are the party number for the Convergence ic's that I need to buy now. I am almost certain that is exactly what I need, now seeing that Chris Palmer had the EXACT problem as I do.

    Ok, I replace the IC Subconductors STK392-040 and I still have the same problem. The top and the right side of the screen are bowed in and the blue will not align. What else could the problem be?

    Aside from fixing the IC STK392-040 what are the other possibilities that I need to look into fixing?

    Hi again,

    Appreciate the update. Resistors 4 150ohm 1watt and a few of the 3.9ohm 2watt resistors and the little pico fuse should also be checked.

    Perhaps it will be best to get hold of a service manual or at least a schematic diagram that you can compare voltage readings. Manuals are available at http://servicemanuals.vstore.ca/. They can also provide you with additional information and one of the owners is a member of this site.

Ck low ohm resistors 3.9 omh and pico fuses they look like resistors but they are green or yellow 5amps, 6amps,sometimes after replacing STKs there is bad resistors or open pico fuses.

Convegence board


your model has the Ics and resistors on the sub delection PCB board. You can get a new replacement board at the following link with free tech support to help you install it as it the entire large circuit board on the right side of the set. You need the board called the P54A chassis Sub deflection board under their Samsung parts category.
Heres the link.

Samsung HC-P4752W 47 in. Rear Projection bigscreen TV


You dont have to remove the aluminum heat sink. The ICs are attached with screws and then just unsolder the ICs from the circuit board and then replace the new ics into the pin hole locations after applying heat sink compound onto the back then screww the new ICs to the heat sinks then solder the pins. Very easy repair.

RGB COLOR PROBLEM.


You will need to check the plus and the minus convergence voltages in the main power supply. There are a couple of circuit protector fuses that go bad. Do not replace these untill you replace the convergence IC's or you will cause more problems in the main power supply. Good Luck
