Got a really a really nice condition Powerbook 180c. The screen seemed to have 2 horizontal rows of pixels out sometimes when I turned it on. Sometimes it was fine though. I recapped the electrolytic caps on the display and sure enough there was a ton of leakage to clean off both sides of the board. I did so and upon booting it up, it seemed the problem was solved, but the next time I switched it on, one of the lines had returned. I guess its possible I could have damaged the ribbons going to the lcd during soldering, however since the lines were there beforehand I'm inclined to believe its a different issue. Opening up the display and tapping/pressing on the ribbon cable where the blank row is doesn't seem to change anything.
I've heard of people running a soldering iron over the ribbon cable to repair the lcd on old Gameboys, though I don't know if anyone else has tried that on a PowerBook. I also read on another thread of someone baking the display at 200 degrees, but the issue he was addressing seemed to be more about ghosting and artifacts rather than an entire row of pixels out. I'd be super grateful if anyone had any tips or things to try to get this display fixed, thanks!
