A day after I purchased my PowerBook on eBay, it began to develop black lines along the bottom of my screen. I could literally watch a new row of pixels slowly blink out, sometimes forming an alternating pattern before becoming a solid line.
Disconnecting the inverter cable is the last operation before the LCD panel can be completely removed.
The lines continued to fill up the lower inch of the screen, though it seemed, that it would only be a matter of time before I lost an inch of the 9.8" screen. The solution to repair this was to simply replace the LCD screen.
Taking apart the casing of the PowerBook's display housing is not a difficult task. It requires removing two screws using a T-8 torx driver. Then pulling down and away the display bezel.
Then four more screws need to be removed to detach the LCD display.
The trickiest part of this process is to remove the ribbon cable from the LCD display. It's a rather delicate ribbon, and removing it from the connector and the adhesive holding it to the LCD display must be exercised with care.
Disconnecting the inverter cable is the last operation before the LCD panel can be completely removed.
The most difficult operation for me in reassembling the unit was reattaching the ribbon cable back into the connector.
It took multiple attempts to push the ribbon into the connector and slide the locking tabs back.
