    Vizio E470VA- Need advice on PC Board

    Hi guys! My name is Sam. I've been lurking here on badcaps for a while now finally couldn't find an answer to a question I've been having.

    First of all, my experience level is fairly low. I've been building my own PC's for about 10 years, and recently started to repair capacitors on power supply's of LCD's I own/pickup as a way to learn more about TV and LCD repair.

    Recently I picked up a Vizio E470VA off of craigslist.

    When I power on the TV, the vizio bezel light will turn on and the backlight will glow while the screen will remain black. The previous owner claims that the sound still works, however I haven't been able to figure out how to test that without know what input it's on.

    All my symptoms appear to be the same as this thread. From that thread and what else I have read on this forum and the interwebs, it would appear that the problem is most likely the PC Board. Unfortunately I have been unable to find the exact part. The current PC Board part number is TQAPT5K00901. Every place I find that has it is out of stock. Ebay however has multiple Vizio E470VA PC Boards, but their part number is TQAPT5K00301. The parts look significantly different even though their numbers are only different by 1 digit.

    My question is- Do you think this different PC Board for the same TV model number may still be be compatible? If not, do I have any other options? Any advice or suggestions would be greatly appreciated. Thanks!

    I would not risk it doesnt look as if there are fixing positions for an alternative board
    and perhaps it has different sockets for the ribbon cables. Perhaps they used different panels as well

      Too bad that the OP of that thread on the link never post the follow-up on the repair.
