PowerBook 520c Display Issues

[akator70]

This 520c display was working fine in January. Yesterday I booted it up to discover this strangeness on the bottom right of the screen. It's different almost every time I boot.



I have swapped different displays and cables and those are ruled out, this is definitely an issue with this display.

Is this a capacitor issue or something else?

Thanks!

ACF ribbon bonding issue or a failing driver IC. Likely the former. Essentially, the issue is that the ribbons around the LCD are attached to the LCD matrix via a specialized ACF bonding machine, and you need one of those machines to fix it (they cost way too much money for anyone outside of factories/large-scale refurbishes to buy them) You can sometimes get away with using another source of heat to re-adhere the ribbons, but this usually doesn’t work.
Basically the LCD is hosed

Thanks. Sad but not unexpected.
