The Convergence ICs will need to be replaced , 95% of the time thats the problem they are on the sub board not the convergence board. You will need two STK392-040 ICs . you can get replacements at the following link and they will provide free installation instructions along with free on-line tech support when you install them. takes about 45 minutes. Heres the link.

Convergence Board for hcl4715w Samsung TV


Part can be found at http://www.vancebaldwin.com - the part is located on the floor of the tv, inside, the middle board. You will have to unplug the tv, carefully remove the back (and front speaker cover) of the tv, and unplug all of wires coming into it. You will also have to remove all of the screws holding it down. The replacement part will fit exactly into the same place - screw the screws back in, plug the wires back into the same place (if you've ever replaced memory in a computer, this will feel very familiar). Once everything is plugged back up, plug in the tv and restart, then run the smart convergence from the remote.

If your TV does not power up, and you have made VERY sure everything is plugged in correctly, then the board you've purchased may be faulty. Return it for a new one. The boards are fragile and can be bad straight out of the box (like computer memory *smile*).

Best wishes -

TV won't power on


Disconnect the convergence board and see if the set comes on. If it does, and it probably will, replace the convergence board or the convergence amp IC's. Good Luck
