I am still stumped
Is there any voltage at that fuse ?

Re: Vizio XVT3D650SV - Help
check the voltage regulator in the second foto of your last post.
7805 should have 5v coming out, and over 7v going in.
pinout is printed on the board.
check any others you find too.

Re: Vizio XVT3D650SV - Help
the part that I thought looked iffy in the first picture looks better in the closeups.
The fuse , on the other hand, in the second picture might be blown.
Use your voltage tester and check voltage at the side that is closest to the plug and then check the other side of the fuse.
If power is not going through. Unplug the plug from the power board and if your tester has ohm readings- check the resistance on the outgoing side of the fuse against the ground (pins marked in black) to see if resistance is there or if it shows zero which would mean a short.
There is also a fuse like this on the 4 pin plug that is near this plug that can be checked.
If you do not have power to either side of the fuse, it may not be powered up yet and would have to be checked with just the ohm meter by touching both ends of the fuse . I n this case, you do want to see zero on the reading.

Re: Vizio XVT3D650SV - Help
probably the main board
Can you post a straight on picture of that board (near the boitom of the board, one part looks burned, but that could be a shadow ??)

Vizio XVT3D650SV - Help
Hello all,
I am reading and reading but can not seem to find what I need to get my TV working again.
When I plug it in, the Vizio logo glows orange. It then dims a little but stays solid orange. I have no picture and no sound. The TV does not want to turn on at all. I replaced the power board with a tested good one. Nothing changed.
I am GUESSING it is a problem with the main board but not sure. I have a multimeter I just need to be told what to test and I can certainly do that.
Attached are pictures. Thank you guys so much for the help in advance!
