    My Samsung has the same problem. When I turn the power on, there is no picture and then the tv proceeds to repeatedly turn itself on and off. Is there anything that can be done to fix this?

    Hello,

    Having same issue, when pressing the on button all I get is a blinking red light for 10 seconds and then shuts off.

    Same problem. New convergence board, new hybrid regulator same problem. Manual for this stinks. Trying to match up pages of the main board, and to locate voltage sources impossible. No Photofact on this. Samsung Techs want to just swap out the $500+ main board. I give up.

    Open for suggestions. Planning to just sell it for parts.

If you unplug this board and the set runs. then something on the board is shorted. causeing the set to got into protect. if its convergance board like your saying, then you need to replace the 2 ic's on it. i believe they are stk392-040. can't believe people on here would beat around the bush about telling you what it needs. if you are not any good at changing ic's then you need to contact your local repair shop. avg cost would be in the rang of $150 - $350. good luck.

My samsung model- HCN4226W T.V will not turn on


You should always have all expensive electronics on a surge protector. It sounds like for this set the power regulators blown out as I know this set very well and seen it a hundred times!! its a power regulator IC that cant handle a power surge at all. and if thats your only problem, it shouldnt cost more then 175.00 to 250.00 to repair. Now with a surge though there could be other problems as well but from what you stated Im guessing alls ok except what i stated. Now Please do not attempt to repair yoursels, as these sets have alot of Hi voltage inside them even when they are unplugged.. Good Luck
