    Try un-plugging it from the video board, and see if the green light will turn on. Perhaps the T-con has a short which is keeping it from coming on.

    Have we ruled out the T-con?

    If the chip is bad, I would say you need to get a new board.

    If the chip is not getting enough voltage, we will have to see if there is some sort of small voltage regulator on the board.

    Im kind of wondering if the chip is powered by the 5v-standby all the time, or only when the TV is off. If so, maybe there is some sort of controller/power router circuit that is dud.

    until I can find the datasheet for the chip, I dont know.

    I cant find anything about that chip.

    all I know is its made by MStar.

    Their useless website:
    http://www.mstarsemi.com/index.php

    They do have a contact though, you might have to contact them to get the datasheet.

    We need the more advanced forum members to help us find this.

    Perhaps we can find a datasheet on this board, that might list the model of the processor, and give its pinouts.

    Tieny, measure the voltage at the top end of RS34, it seems normal for the base to be about 0.65v, because RS34 limits the current. I'd expect it to be somewhere around 2-3v.

    I suggested finding the processor model, so we could find the pins for it's Vcc (+V bus), and measure those.

    Yes, that is a lot for 32", but a year from now it may get a lot cheaper, so wait for it.

    A bit too pricey, I might just have to bail out on this one =/

    The main thing is that you have to match the number as printed on the white barcode sticker.

    I looked around on ebay, found one for 50$ at the lowest, but it says its for the Dynex DL-26-10A however its the same board number. I'll look around elsewhere to see where else.

    The board number is 569KT0169E

    and heres the one I looked at http://www.ebay.com/itm/DYNEX-DX-L26...item3a775ba5c2
