Samsung HCN4727W Hello, My television will not turn on. If I plug it in, or press the power button the red led lights up 10 times. Every other blink is slightly longer the the other. Are you familiar with this problem? Thanks you in advance for your help. Phil

Could be a convergence issue...have a look here:

    Unplug the tv. then Try unplugging the connector CNZ03 from the convergence board. It is the red one on the left with the two blue/green wires. Plug the tv in and mine powered on imediately but you may have to push the power button. The led on the front was still doing it's flashing thing but the tv powered up, and made its happy little chime sound. The screen looked like a typical bad convergance issue, and rightfully so because the power has been removed from the convergance board. If you get similar results then most likely you need to do a convergance board rebuild. mine has a couple of burnt resistors and I am assuming that the STK392-040 IC's are bad too. If your set does not turn on and power up then you should search for other issues.
    This may save you the added expense of replacing parts that are not bad.

    I will try to re post once I have rebuilt my convergence board to let you know how it worked out and if the blinking light goes away.

Samsung HCN4727W 47 in.

I mean that your unit is need of resolder or reheating of the solder joint of the parts.Supply section,horizontal section,vertical section and microprocessor IC.Improper distribution of current flow ,due to a loose contact or crack solder, that's your tv automatically signalling by flashing,that is the main cause of flashing . Find a tv technician to do works for you,,in order to avoid high voltage shock....
