That might be a bit more expedient. I have CRC CQ electronic cleaner which I can use to spray both sides of the board before baking. I guess I don't have any silicone spray for after I bake it though, is that strictly for the process to work or is it more of a nice-to-have step?

Uniserver: I live in the US so I guess Pledge it is. I don't have any right now and I assume something like Lysol wipes wouldn't work quite the same way, so I'll pick up a can when I next have the chance. Elfen: Yeah thinking about it putting WD-40 in the oven couldn't possibly end well. I have...

Thanks for the information, although I'm not Australian and not sure how that came about  :) I checked my multimeter and it turned out I had it set to measure AC instead of DC. When I double-checked everything and looked at voltage on the rails, the readings were far more sane. +5V read a...

I have an update on the motherboard issue I've been experiencing with my LC III. I've gone ahead and tried various suggestions with the following results: 1. I scrubbed the affected area of the motherboard near the sound chip, audio jack, and speaker connector with CRC QD electronic cleaner and...

Thanks to everyone for the great replies. I probably won't get a chance to look at the board in closer detail until after the holidays are over, but at least now I have a wealth of potential troubleshooting techniques to go through.

Regarding the numbered items: 1. I'm not sure what A/D means specifically but I went ahead and took pictures of the relevant parts of the motherboard and then some. Let me know if higher quality pics are needed or if a specific area needs further attention: http://imgur.com/a/HrYCr 2. I made a...

Seems like a good idea and easy enough to do at home. I'm not familiar with PCBs but from what I've read the procedure for washing would be as follows: 1. Remove the PRAM battery and RAM stick from the motherboard 2. Detach the motherboard and put it in a tub or other container 3. Use 91% or...

I've been maintaining what was formerly a fully operational LC III for the past couple of months following the completion of board and PSU recapping (c.o. Uniserver) but a few weeks ago I noticed that the internal speaker would occasionally make a popping noise. The issue seemed to get...

Thanks for the response. I've ordered another DB-25 to CN-50 cable since I'll need it in the long run, so in the worst case I can transfer from internal HD to zip disk, then zip disk to external HD. Regarding the soldering, I'm assuming that soldering the wires would be only if I wanted to be...

I was working on my LC III (again) and tinkering with the two external hard drives I acquired some time ago. It turned out that one of them had a functional hard drive but the enclosure's power supply was not working, while the other had a perfectly OK enclosure but the hard drive itself has...

The chimes of death issue was unrelated to the external hard drive and was resolved after having the LC III recapped. Using the end-point terminator instead of the pass-through terminator worked and I was able to view the external HD on the desktop without any problems.

Received the recapped LC III, it's back in proper working order. Thanks!

Yeah I've heard good things, sent an e-mail so we'll see how the board fares.

Well that's no good. What can be done for the board apart from replacing the caps? Are any of the fixes time sensitive?

Here are some pictures of the board. If they're not sufficient, please let me know and I can try taking more photos. http://imgur.com/a/uaju9 The board appears to be intact, but I'm far from an electronics expert and wouldn't know what to look for in terms of something being wrong unless it...

I was trying out different SCSI configurations for an external HD when I noticed my LC III started giving the chimes of death immediately after startup. I can't see anything on the monitor, possibly because it is using an adapter, so I can't tell what specific error is occurring. I tried...

An update, I got a regular end terminator, so now my SCSI chain looks like this: Mac <-> DB-25 to CN50 cable <-> External HD <-> CN-50 terminator However, now when I try turning the Mac on, it gives the chimes of death. When I used the pass-through terminator it would at...

Okay. So an end terminator such as http://www.ebay.com/itm/New-Retail-Centronics-Centronic-50pin-50-pin-Male-External-SCSI-Terminator-Plug-/290646229287?hash=item43abdd8127might potentially do the trick? Even if not, it might be good to have one on hand for the future. Just want to make sure...

As a result of the feedback I got from the topic at https://68kmla.org/forums/index.php?/topic/26059-lc-iii-external-hard-drive/I was able to obtain an external hard drive which connects to my LC III via the DB-25 port. The setup looks something like this: Mac <-> DB-25 to CN50 cable...

Sorry for the double post. The 40MB Conner drive is working great, but I happened to come across a 1000MB Quantum drive recently which I tried checking out on my LC III. Although the drive appears to spin up correctly and the computer appears to behave more slowly with it attached (even...
