Is there any sound? Did you order the exact main board part # as your original board?
I did order the same main board (3642-0502-0150(A)). I put substitute inverter boards in and my backlights work great, but the inverter boards would not have caused this. The only sound is just the normail very faint humming of the backlights and the power board and very low volume static from the speakers. i tried to connect one of my old dvd players to try to get sound however i don't think the one i used will still spin a disc and i can't remember how to blindly change the source input if i can not see the screen. I thought it may be a bad lcd screen (i hope not) however these are very wide vertical bars not the usual pin thin line you would normally see from detached tabs.

You will have to isolate the main board and Inverters.
Unplug the inverters and turn on the set.
If it "turns on" then try re-connecting each inverter seperately to see if only one is causing the problem.

Update. I can make the TV stay on now however there are vertical color bars across the screen. The bars eventually do fade and the tv and backlights stay on. Still no picture or response when i push any button except power.
