I swapped out the SuperDrive with an SSD. Closed it up and get the chime, LEDS 1-3 on, LED 4 off, and fan at full speed. Connect an external display to confirm everything is working fine...except the display. I've disconnected, connected the LCD cables several times and replaced the data cable with same results. Only remaining possible causes can be bad connector or LCD. Connector looks good with no damages to the pins at all and I find it difficult to believe that the LCD was damaged as I did toss it around or yanked cables out. I don't know what to do next. I can only think to try a new LCD and pray that is the issue because next step is to replace the logic board. I've never soldered before and I won't be good at replacing the connector. Appreciate any advice.
