Question about Samsung HC-P4752W 47" Rear Projection HDTV-Ready Television

1 Answer

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

I have a Samsung HC-P4752W 47 rear projection TV. I changed some settings in the service menu which has caused this unit to keep on turning itself on and off every five to ten seconds.

Any ideas as to what could be the cause of this? would you happen to have the recomended factory settings for the service menu?

Please assist

How do you get into the service menu on Samsung hcp4752w


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.

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

Samsung HC-P4752W Blurry ONLY on HD Channels


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,,,
