Samsung HC-P4752W 47 turns its self on and off.

COLOR CONVERGENCE IN THE MENU

I dont remember it exactly but ..if your TV is on then Press Standby and then press Info + Enter + Menu + Standby to turn on..you will get the service menu on screen.

Just alter the sequence of info + enter + menu to info + menu + enter or something.

hope it works

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.

It sounds like there is a fault on the chroma panel of some kind.

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.

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

I want to get this straight are you saying that you cant align them
and this is your focus problem or you have two problems that you cant get the convergence and the focus?

it might have been easier just to have the board replaced...

Need all the facts for research = what board part # was replaced ? cost ? Do you have original board ? Was work done in your presence ? total cost ? Help me so I can help you.....T.

Similar problem, then about 2 weeks later the SD convergence went out. Changes convergence Amps,,, Now I'm trying to learn what 2 red flashes mean now when I try to power it up,,, it flashes twice then shut down into standby mode,,, I got no picture after installing STK392-040 chips, thinking about trying another set as atleast I had blury picture before. No solder shorts of opens that I can find. TV has always been a pain,,, locking up once in a while such that you can't change modes,,,
