LG Plasma TV Model # 50PJ350-UB
In this video I show how a shorted component on my main board
causes my stand by power to be lower than it should be, and how UN-pluging the main board allows the 5 volt stand by power to return to normal, indicating there is a shorted component on my main board.

    Hi! I have to replace the YSUS EBR63039802 board. Besides the two connections are they any other connections that I need to make? If so, do you have any video that would help me how to install that board?

    if i unplug the board in your video from the main power supply that you replaced and plug the power supply in, the tv turns on but when i connect the board back to the main power supply the tv shuts off. im guessing its the board you replaced in the video as well. Any suggestions?

    Thank you for your informative videos. I am an Electronics Beginner and have a KORG full size electronic piano I am trying to fix. All I've done is open it up and looked at all of the capacitors but all of them seem to be good so far.

    Thanks 4 your videos, as a beginner i love the info
    i have a similar problem with my samsung T200hd LCD monitor TFT that suddenly stopped working…. There's also no sign of live at all…  I also replace the main board & powerboard but that didn't help.
    Any idea where to look ?
    Could it be a broken backlight or convertor board ?
    Thanks
