Thanks that must be it, looking at the data sheet for the LCD the following wires are broken on the ribbon cable.
12 - GND
13 - B0 - BLUE Data Signal (LSB)
14 - B1 - BLUE Data Signal
15 - B2 - BLUE Data Signal (MSB)
I guess the patch (attached photo) isn't adequate enough. Probably too...
I finally got around to fixing a PowerBook 180c that had a broken hinge mount and broken ribbon cable. After a couple years on the look out for a new ribbon cable have ended up fixing the ribbon cable by bypassing 4 of the wires in the ribbon cable were severed with some individual wires. Also...
I ran into another problem with the DynaMac, the Mac Plus logic board developed a fault, think a while ago probably before repairing the PSU, where it would freeze after being on for more than 5minutes. After much diagnosing (using the board hanging out the back of a Mac Plus and using freeze...
Few weeks ago I got it running, (tried posting on this forum then, but was down). The power supply I used is an XP Power ECP60UT01 bought from RS Components, and a couple of adjustable step ups from Banggood (5v -> 15v & 12v->25v). And I etched a little board to make things neat.
I deduced the voltages by following where they go:
1 Orange: +25v - To display pin 3 & 11
2 Yellow: +12v
3 Red: +5v
4 Orange/White: +5v
5 Black: GND
6 Grey: +15v - To display pin 1 & 9
7 Blue: GND
8 Blue/White: -12v
By following the molex, the Mac Plus logic board...
I have a Dynamc with a blown up power supply (a friend found it in the rubbish), Am interested in restoring it. I don't think the power supply itself is salvageable (unless I have the schematics). The hard drive definitely still works as I've tried it on a another Mac.
Question is does anyone...
