Repair nightmare with Samsung LCD/LED experts pls help!

[fabes253]

I have a Samsung UN55C7100 and I am in a repair nightmare. Please if anyone has knowledge I would greatly appreciate help.

1st - One day the Panel went out, it had vertical lines through it. Samsung agreed to replace the panel so a technician came out and replaced the panel and F-Con board.

2nd - A week later the TV died, apparently it was a power supply board. I ordered a new power supply board (refurbished) and replaced it myself, The TV worked for a week and then it seems like the power supply board went out again!

Is this just my bad luck? Or is there something with the new panel that is blowing the power supply boards? Currently it makes a click sound like it does when it will come on, then you can hear a power sound like its trying to power up, and nothing happens. It repeats the click and power sound over and over.

Do you not have a lemon law in the states? Samsung should come out and replace that board, or offer you a refund / discount on a new TV.
It's more likely you have a main board fault than a power board fault, IMO.

Well the TV is out of warranty by a year. Through my many complaints they finally agreed to replace the panel. They said they would not do anything else for me considering. Would a bad main board cause a power supply board to fail?

Not sure on this model you would have to find the service manual or the field guide...

Unplug cable from power supply to main board. Plug set in. Do the backlights come on ? If so suspect main board. If not suspect power supply or backlight system (leds).
