I took this apart to replace the failed disk with one that will need formatting. After reassembly the system bongs and I can see the back light came on. But nothing after that. My suspicion is that the display connector is damaged. It bends away from the PCB just a bit. All the leads going to the PCB seem intact, There are ears one either end that look as if they might should be soldered to the PCB. The plug from the display to the PCB does not seem very secure but visually it appears fully inserted. So, how should I proceed with debugging this? Given that it is almost nine years old I am not inclined to invest much more time or money. Update (02/18/2018)
Well, the top image seems to show the problem. The underside of the connector seems to have pealed away from the solder pads. My EE degree is now 48 years old and I have not done component-level work on modern PCBs. My only soldering iron is almost that old and probably not suitable. What is the proper tool for repairing this kind of damage? Update (02/18/2018) One more photo, showing how the connector is lifted from the PCB.
Well it looks like you found the problem. One contact appears to be pulled off its pad as well as the frame pads have been pulled. You might be able to take the connector off the rest of the way so you can reform the connectors solder pins or replace it with a new unit. You don’t want to press the connector down as you may break it or warp it so the connections don’t mate cleanly I-PEX connectors
