imodfrenzy Posted October 17, 2017 Report Share Posted October 17, 2017 Sorry if this is in the wrong section but I recently pulled out my PB 540 and decided to try fixing some problems. These are the problems its having: -Screen is cut off on lower part unless putting pressure on it. -LCD Cable has been cut a little -Audio doesn't work -Not sure if this is an issue but the screen begins to fade from all edges to black after a while. I uploaded a picture of the LCD needing pressure to actually work, and the hinge cable being cut. I figured since this is the only cable going to the LCD that maybe the connections to the audio had been cut on the ribbon cable? (There is fewer wire lines on the cut area, forgive me if I'm way off). Would the pressure problem be an LCD issue if anyone knows? Also I read about capacitors often going bad, should I check around for leaking capacitors? Thanks Quote Link to post Share on other sites

tjjq44 Posted October 17, 2017 Report Share Posted October 17, 2017 (edited) All the symptom except the corner getting dark seem to come from the ribbon cable you mentioned (audio uses this cable too). Try to find a spare ribbon cable. For the darkening corners, it's a well known weakness of apple's monochrome active displays and there is no real fix for this... sadly Edited October 17, 2017 by tjjq44 Quote Link to post Share on other sites
imodfrenzy Posted October 17, 2017 Author Report Share Posted October 17, 2017 Alright , just ordered a new LCD cable for it so ill update here how it goes when I get it And ah I see, is it possible to swap to a colored screen? Or they use a different display cable Lastly, I’ve though about getting a CF card to replace the HDD, this is possible right? I’m unsure what size is the max for these macs Thanks Quote Link to post Share on other sites
Strimkind Posted October 18, 2017 Report Share Posted October 18, 2017 The 5x0 screens are all swappable, as they use the same logic board. If you can find a parts unit with a good colour screen, it would be ideal. As for CF, all the 5x0 series use the old SCSI 2.5" format. You will need to get the 2.5" version of the SCSI2SD, linked here: https://store.inertialcomputing.com/product-p/scsi2sd-v5-2.5-inch.htm Quote Link to post Share on other sites
tjjq44 Posted October 20, 2017 Report Share Posted October 20, 2017 (edited) Be very careful when you install the new flat cable not to pinch it! Especially when you'll reassemble the powerbook in putting back the side "conic" plastic tab... Edited October 20, 2017 by tjjq44 Quote Link to post Share on other sites
CC_333 Posted November 17, 2017 Report Share Posted November 17, 2017 All LCDs are interchangeable, but bear in mind that the cables that connect it to that "interconnect" board (not the main cable that goes to the logic board) are specific for the type of LCD (ie, Active or Passive matrix, color or greyscale), and those are *not* interchangeable from what I can tell (I tried it, so I know). c Quote Link to post Share on other sites
