    Macintosh Portable non-backlight replace display options

    What are my options for replacing the Active Matrix panel in my non-backlight display? Are there any options other than using a display from a similar Mac portable? I have a PowerBook 170 display which I know is backlite with different connector.

    Macintosh Portable

    This is photo from Mac Portable non-backlight. Trying to recap and repair the traces. I noticed the 2 tinned traces coming from R22 show continuity across R22 resister. Should they show continuity? What is likely causing that if not?
