whoever soldered this capacitor shorted this trace (I accidentally added this text box and can't remove it on my phone) 

Oh no, I have failed you!  I'm very relieved you found a solution, but I'm definitely sorry I didn't pay more attention to the trace damage. 

 

[Johnnya101]

It was an honest mistake! I really didnt think it was your doing at all. I just happened to noticed the exposed copper traces and then saw a little dot of solder shorting out a trace. I forgive you! Amazing work otherwise.

Im happy to have a fully working PB140 now! Gotta unstick the hard drive, its jammed and clicking. All simple stuff from here on out. The speaker clicking seems to have been software related, I dont hear it now that there is no OS to load.

So happy it was something little like that. Now a fantasticly sharp LCD can be used once again.

If you take a look at my previous photos, you will notice what appears to be a dead pixel on the bottom left corner. Its gone now too, all related I guess?

Ok, so a couple of questions...

First of all, the connor hard drive seems to have kicked it. It spins up, spins down, spins up, etc. Never boots. Got it to boot once but now it wont stay spinning. Swapped it out with another connor. THis one doesnt even show up in HD SC. Are these fixable? If not, should I just drop in an SCSI2SD Powerbook edition? Kinda pricey at $80.

Secondly, the speaker clicking seems to be consistent with drive usage, When I boot from a floppy, there are a few clicks and as soon as the desktop is loaded, they stop. Is this a power adapter issue or logic board thing? Power adapter has been recapped.

Heres a glamor shot of me attempting to install 7.0.1 only to find out the drive is dead. Really sharp screen. Faint line in the middle but Apple says thats normal.

Congrats! Glad you took another closer look at it.

The line in the middle is indeed normal. It is the split point between the top and bottom half. Like I said above, the passive matrix displays are split in 2 to help with rendering.

Now I have to see why it clicks sometimes and what I should do for a hard drive. I'm thinking an SCSI2SD Powerbook edition. Anyone have experience with those?

As for the clicking, I've tried a different power adapter and there was no difference. I wouldnt rile out though both drives being bad and sucking a bunch of power causing the speaker to click.

Bought an SCSI2SD Powerbook edition and will design a bracket when I get it and update here.

In the meantime, if anyone has ideas on how to fix the clicking sound, that would be appreciated.

good work on fixing the display!

Received my SCSI2SD powerbook edition the other day, and got busy creating a bracket.

Here it is:

Installed it. The bracket fits nice and snugly just like the original Connor drive. Had to install a small paper shim on the top "filler" block.

Downloaded the patched HD SC setup and used it

And installed 7.0.1...

I can verify that the SCSI2SD Powerbook Edition works excellent with default normal settings that would be used for desktop Macs. Now all I need to do is load some software on it.

If anyone has ideas for the clicking, that would be helpful. It is still there with the SCSI2SD, but seems to only occur with lots of disk activity. It wont happen if it just sits there idling.

A problem with the PSU ? those are prone to failure..

 

[Johnnya101]

No, I tried another I had. No change.
