Re: Toshiba 49U6763DG
Take a picture of the tcon/board bonded to the screen.
You may have 12v but let's see what other test points are there. Since you still have sound and the tv functions as normal I'd doubt that the motherboard is faulty at this time.Leave a comment:

I created a thread on repairing this power supply not so long ago. I think you may have the same problem.
Unsteady output voltages is usually caused by one of the smd diodes failingLeave a comment:

Don't bake your motherboard would be the first bit of advice.
Take a picture of the tv with the back cover removed so we can see how it connects to the screen.Leave a comment:

The vs and va voltages will only show initially then will drop back to 0. Unhook the ysus and test vs and va right as you power on the tvLeave a comment:

Anyone else noticing higher volumes creeping back into a lot of budget brand tvs.
Those MEGMEET powersupplies are particularly prone.
assuming, of course, the LEDs dont go first. -
