Samsung HC-P4752W Does Not Turn ON

My two year old Samsung HC-P4752W has stuck in standby mode. It started when it was one month old, it would turn off itself and enter the standby mode where it would remain until it is unplugged from the power line. I reported this problem to the manufacturer who directed me to a local TV repair shop; unfortunately, this local shop did not identify any technical problem and hence it was not fixed. I had to live with this problem for another two months after which it dissappeared itself. For te last one year and a half I had no problem with this TV. Two weeks ago it developed a convergence problem, which I was able to fix myself by changing the STK ICs because its warranty has already expired. However, the old problem of self turning off as I described above restarted. This time it survived for only one day after which, it failed to restart completely. Currently, the TV has remained in the standby mode. Nothing happens when I press the button on the TV set itself, however, if I press the power Key on the remote, the TV responds by turning off thr standby LED. I think I have given sufficent information that to descriobe my problem for the expert to help me solve this problem. I guess the problem is not very serious, however, I strongly need help. I have no confidence in the Local TV repairman because they failed me when I was still under warranty.

Re: Samsung HC-P4752W Does Not Turn ON

The proble you have is an intermittant power supply or sweep power supply. Unless you can find a bad connection on the power and deflection board, this could be a very difficult problem to find. I have ran across this problem a couple of times, and after spending countless hours troubleshooting, I replaced the main board and all the problems were taken care of. The board part number is at and I found the board for you. it is located here: Good Luck

My television is a hc-p4752w and the color convergence is way off. The red and green are not together and curl away from the top of the screen and bottom too. I tried to auto focus with only making the color separation worse. The tv is about four years old with lots of play time...

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,,,
