Just got it taken apart and pleased to see only a few electrolytics to replace (though none obviously blown or leaky).

Some evidence that the display had been squeezed (sat upon?) at some point in its history and had a slight curve in it - that could suggest problem with ribbon cable connectors on the side of the screen. When I get the caps replaced I'll try installing a pressure strip on top of the ribbon connections to see if it restores video to that missing region.

I'm reluctant to risk testing the display without fully re-assembling it - I blew up a G4 Lamp logic board once by running tests without full heat-sink contacts in place.

Does anyone have suggestions on how to test screens safely in a disassembled state?

I also have a PB160 with totally dark display, so I'm getting both sets of caps, which may take a while as not all are available where I live.
