My Vizio TV D50x-G9 won't power on at all. At first the TV used to come on but it was a zapping sound for about 2 seconds coming from the back of the TV I think where the control buttons are and then I would try to turn on TV but it wouldn't come on but the power light would flash flash and go din,flash and go din repeatedly but the TV wasn't powering on. Now the TV won't power on at all with nothing coming on. Seems dead. Is the TV in my guest room and I never use it It's was a brand new TV. I'll just go in there every once in awhile and turn it on just to let it run for a few minutes. I'm guessing is it the power supply board? Or Maine board or something else?????. I was going to buy your power supply and main board combo But if it's something else please share. And is changing the power supply or main board complicated? Or can I unplug the wires and unscrew the faulty one that's on a TV and plug in and screw the new one in or is it more to it. I really don't want to buy a new TV because it's already a new TV and rarely used and it just became out of warranty
Bad TV PSU (power supply unit) and seems dangerous to me.
arc'ing? sounds. I'd not plug it in to AC wall power until fixed.
did water land on TV?
why not get a shop to fix it?
or buy \the shop manual
the manual you don't have may say
the main board needs to be reprogrammed to use this size 50" screen, and if not done by the book there is no hope.
learn to RTM first, no 2 TVs are the same.
some have 1 main logic board that works on 3 screen size models.
why not get shop to do that? and not pour cash down a pit. to zero gain, why?
what if the PSU was overloaded, even the LED background array can do that if bad. so replacing the boards 10x will not cure that. see???????
next time by LG or Samsung. far far far better long lasting TVs
and 10x better service, (consider that)
