Hello, new to TV repairs and electronics in general. My Vizio 50 inch plasma TV from 2007 went completely dead save for the amber standby light. I was able to source a used power supply from a TV repair shop (a Sony power supply that was told is better than the LG that came with the TV). It still did not work until I bought and installed a main board. I now have 99 percent of the TV back. I have a vertical one inch line that runs on the left side of the TV. I was trying to decide if I damaged the PDP during the repair or if it is something else. The line appears to boot up white and then sparkles in areas changing into multiple colors. It does not affect the TV since it is localized within the vertical line.
