problem like your is a "guessing game". I will try to locate Vizio XVT553SV with a crack screen. or you can try to replace the main board or power supply first.
Please see post# 18, I have replaced the main board and now the TV is fixed. I am looking for help just to troubleshoot the problem on the old main board. Now that I have a good board & a bad board I'm hoping to get help to try & find the problem on the old board so I have a spare.
To be honest, most of us tend to avoid troubleshooting main boards... It's very difficult and with a very low success rate. The only main boards that have been solve are just the common problems we've all seen before.

okay, my bad. I agree with Glitcher. Troubleshooting a main-board with out a schematic is a challenge.
