Vizio TV died a few days ago, 37" SV370XVT. TV was on, then just shut down. I took off the back and replaced the fuse on the power supply board. When i plugged it in, the fuse blew immediately. I replaced it again, and disconnected the main board and the X-Y boards from it. Plugged it in again, and fuse immediately blew again. Does this sound like it is probably a bad power supply board, or is there something else i should check on before ordering a replacement board?
Thanks in advance.
