Blown L9000 for LCD power connector
I have 27" iMac mid 2011 which required LCD replacement. I bought another dead iMac to pull lcd and Led inverter board. As soon as I plugged it and blew L9000. iMac stills boots with chime but no display(not surprised) with fans running full speed. Closely inspecting i saw broken data cable for new lcd. So my questions are:
1)Could the bad data connector have caused this?
2) Can bad LCD or LED backlit be cause of this, if yes how to test it?
3) Can I take this connector and take input from somewhere else example solder wires to to 12 v supply from power supply or use other backlight power?
6) Is there any schematic available for the graphics card connector and lcd connectors?
Picture of logic board, connector and potential connector attached. The one in picture is in bad shape, other logic board has only L9000 burned out. I will post pictures after cleaning it up.
