My Samsung LN32A330J1DXZA LCD TV would not turn on. I did some reseach and came across the capacitor issues that this model was having. Initially, my tv would not turn on but had the power light on. I was disassembling the tv to fix the capacitor when I believe I may have caused a bigger problem! I had the tv still plugged in and the board touched the metal framing which caused a few sparks!!! Now the front power light does not even come on... Could I have shorted out the entire power supply board? Blown fuse? Etc... Any insight would be appreciated. Thanks.
