    Samsung un40fh6030fxza no power blinking power led

    A few days ago a Transformer blew by our house. When the power was restored I went to turn on the TV and nothing would happen. The red Power LED on the front blinks and nothing else.
    Where should I start to repair the tv?
    Thanks ahead of time for the feedback.

    Unplug the cable between the main board and power supply board and see if the backlights come on. Yes - main board suspect. No - PS and/or backlights suspect. With cable connected, report voltages on that connector with tv on and off. There should be a legend on the board and there are two rows of pins. Pin no - Pin label - Voltage Off - Voltage On

      Upload good clear pictures of the whole backside of the TV so we can see what we are dealing with.
      Do you have tools?

        Thanks, I'll try that out as soon as I get a chance. And upload pics asap. It will be a little while before I can get to it though.
        Also do I upload pictures directly here or to an image host and link here?
