Samsung HC-P4752W 47 in. Rear Projection bigscreen TV

Hello I have a Samsung hc-p4752w (rear projection big screen TV) and have been noticing drastic change in color to a blue tint that appears to "ghost" the image on the screen to the right (almost layering the actual image and ghost image). I have ordered two SDK392-010 's but cannot remove the metal (aluminum?) "casing/holder" that holds the IC's in place. Am I on the right track with the IC's, and if I am how do I replace them?

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.

I think you have a fault on the chroma board and on the picture frame board. If you can trace it yourself try these two locations otherwise call out a competant technician. hope this helps.

Not sure of the part number most use STK392-110 or 120s . You will need to look at the ics in your set they will have the IC numbers stamped on them they will have STKxxx-xxx whatever that number is thats the sanyo part number for those ICs
