The lcd screen went dark so I installed a new lcd with the invertor. When I booted up the laptop it still has the same problem. It runs fine with a remote screen plugged in. I ran the internal diagnostics and came up with code 1000-0322 unable to access invertor. I am now thinking it may be the lcd cable but I don't want to just keep adding more new parts till I get some info on this code. Any help would be appreciated.
