I'm going to try to get a FSTN cable to test the original screen, eliminate all variables; I’m back to thinking the screen is bad, the cable is blameless, and I am no help at all. That said, if you want to reproduce my results: putting a 540c screen in a 520c requires two things. cable: SHARP...

fellow in the other thread pointed out the difference in the cables! the FSTN is Color passive, the TFT is Color active. The LQ94D041 was never going to work with the FSTN cable... So i haven't actually solved anything here, simply clarified: match model and cable and then yes, you can swap the...

ffs, i looked right past that; read "sharp color" and dismissed the rest. (see prior, amateur analysis.) (zoom in and the part number is a digit different too, oy.) I skimmed accounts of people swapping the screens from 520c to 540c, i read the references to “match model” as Sharp or Toshiba...

TL;DR finally laid hands on a replacement Color LCD Cable and everything works. It was the cable, it was always the cable. Full story. (also posted in my original thread) i spent a few months lazily & occasionally searching eBay, AliExpress, etc. for "LQ94D041" I figured if I had to replace...

TL;DR finally laid hands on a replacement Color LCD Cable and everything works. It was the cable, it was always the cable. Full story. i spent a few months lazily & occasionally searching eBay, AliExpress, etc. for "LQ94D041" I figured if I had to replace the screen, I might as well replace...

after shot with battle scars. (kapton tape because i busted a clip inside that hinge and haven't printed a fix yet) (before repeated below for contrast)

those cracks are godawful, mine went all the way through--there was no way to even open the lid--i shudder just remembering it. there was no way to repair that cleanly, so my goal was get mass behind the area & spread that mass out as much as possible. (that's why the sprawling shape and...

oh hey, forgive me: i never posted any "after" shots, i guess because [after] was just [powerbook that could hold itself open]. i know exactly what @3lectr1cPPC is saying... here is the lid that inspired my original effort. I’ve glued this same shim into three powerbook 1400 at this point, and...

i would love to get a set--either rainbow if still available or [whenever the next run is up]--tell me when&where to send payment!

you send me a whole top case, i will dismantle it, install a hinge reinforcement shim, reassemble with the B/W screen, and send it happily back to you. Let me know if you need a fake battery or two thrown in. (It really is my PowerBook 520c, my first portable mac, and i’m still crazily...

(was this post dead?? i just figure it was on the back burner... I mean, i have five different macintosh in various states of disassembly all waiting open different things. It’s just a hobby; the journey IS the destination. Here’s my update.) i have been trolling ebay and craigslist, waiting...

This is a model of the battery for a Macintosh PowerBook 1400. It fits the existing battery bay, and includes the appropriate slots to align and latch into place. I have three different PowerBook 1400, and this fit in each of them. You can print an entire battery and insert it as a blank, or...

(*pardon me, i meant between two PowerBook 520, one was NOT "c" I just habitually added that when i was typing... I am trying to find another color LCD for more testing.)

my PowerBook was missing one foot, so i replaced both. also uploaded to Prusa

i think i had the same problem i replaced parts back and forth between two powerbook 520c, and to my experience it was not the cable, nor the inverter board, nor the interconnect board. The only thing consistently did not work was the LCD itself. I found several leaking capacitors on the back...

i should have included them in the original post. the SSD is a Kingspec PATA, i have used 8GB and 16GB the Sled wants me to finesse a millimeter out of it; it fits great but I am never satisfied. the Board was made in Fritzing because i am lazy and fritzing works fine for tiny projects. the...

I have several old PowerBooks that i adore. Okay, lots of old powerbooks. It’s not a problem, i can stop anytime. Every single PRAM battery is dead, of course... and every one of them requires dismantling the computer to get to the battery. Of course. I ordered a handful of new VL2330 to make...

with that tip in hand, i dremyl’d away a little more of the trace before sealing it up; will update with results. related, here is a quick diagram of the wiring inside a tangerine iBook (slightly different colors than the Blueberry at “Brian’s Retreat”)

thank you for this write-up! i just installed a strip with the modifications, and it already looks fantastic. In lieu of toothpicks, i modeled a LED-strip holder based on the existing brass piece. It uses the existing screws & holes, and slides right into the channel. It holds the LED strip...
