    Recapped LC II

    I've had an LC II board setting around for quite some time with a few pads pulled on it. It was really nasty but I some how managed to get it to start up after a really ugly recap. Had to bridge C21 across, turn C15 and C22 a little sideways.... I know the image is a bit blurry, but you get the idea. The pads probably wouldn't have came off if I didn't wiggle the caps off the board. Is there a better way of getting them off? I tried with my iron first, but they were just too corroded. Also, any recommendations for the tip and temperature I should be using on my Hakko 888D?

    PowerBook 160 Contrast Issue

    So I took a long break from my collection and never got around to fixing this issue. I have a PowerBook 160 that doesn't seem to keep its contrast steady. Messing around with the slider will fix it, but it constantly gets brighter, then dim.

    SE/30: Problematic ReCap

    A Performa 475. Still running great.

    SE/30: Problematic ReCap

    That board looks familiar... If it helps, this board worked fine until I tried recapping it with a cheap Weller soldering iron. Those tips just don't last . I struggled around C2, so I could have damaged something in that area. The first boot after the recap gave me a death chime along with a flash on the screen. After that, it was done.

    Color Classic Sick :(

    I was able to boot from a floppy. Sure enough it wasn't able to detect the hdd. I shut it down. Took out the motherboard to look at it. Put it back in. Hdd decides to work again... Monitor went from a yellow tint to normal after running for a bit. Hard to tell, but there is some flickering that comes and goes.

    Color Classic Sick :(

    I got this Color Classic about a year or so ago. It would start up fine but it had this weird issue with the screen being one color until it warmed up a little. I decided to pull it out today and fire it up to see what would happen. I recapped the motherboard last year also. Here is what I found out: 1. HDD Spins up, Chimes, Red Screen 2. Blinking Floppy (HDD must be dead now) 3. 15 seconds or so later, Sad Mac 0003 Turned it off and tried again: 1. HDD Spins up, Chimes, Green Screen 2. Blinking Floppy again (I think i'm going to find a floppy to boot this thing with) 3. Sad Mac again. Found a floppy, but it didn't like it. I think the version is too old. The startup and death chime started to sound a bit odd after a few attempts. Maybe just my imagination. Here is a video I recorded: https://www.youtube.com/watch?v=PywsuX_pzVY Obviously first thing I need to do is get a startup disk and see if it will actually boot from floppy. Whats with the sad mac though?

    Finally Back With Some News! 475

    I need to get some ram. I struggled to find enough vram to get video. I also need to make a system 7 disk as I see system 6 hangs at "Welcome to Macintosh".

    Finally Back With Some News! 475

    I am going to try to keep this easy to understand. Hopefully some of this information below is useful for elfen, even though he is not receiving the death chime. My story: I got this computer about a few months ago. I cleaned the board, recapped, and still had a death chime indicating ram failure. A few times I didn't get the death chime, but didn't have any video on the screen (even after doing the power on/off/on trick). The fix: Apple did not make a wise decision with having 8 vias right under one cap (The right cap under U5). It is also difficult that the traces shift as they pass under each ram chip. Addresses 0-7 on U5 lead to here (RP9 and RP10). In my case, pin 14 of the ram chip went to the bottom of RP10. RP12, RP13, and the others.... Not sure where they go, but might be just as important. This was also very helpful for the pinouts of the RAM: http://www.datasheetarchive.com/dl/Scans-065/DSA2IH00163574.pdf

    Finally Back With Some News! 475

    I'll get some pics and some drawings up soon. I got to resolder my wire because it came undone. I guess that's what I get for using the smallest wire I possibly can lol. I still don't understand why apple would have like 8 vias right under a cap.

    My new Imac

    I stuck my Late 2006 17" back in the original box. Not only did my display have the lines but 1/3 of the screen is a big block of nothing. On top of that my slot loading drive won't eject and the hard drive failed. I replaced the hard drive but never used it much because of the other issues.

    Finally Back With Some News! 475

    Time to give this one more try. I noticed that the corrosion that I attempted to clean off of U5 is still there pretty bad. So I gave it another scrub and no luck. Im still guessing that the problem is somewhere in this area since it was the worst when I originally cleaned the board. As far as traces go, everything I have checked so far is fine.
  12. So I am finally back to working on my 475, the one I posted about back in December. Still the same death chime issue. I decided to hunt down the data sheet for the on board ram, which is Samsung brand. It was actually easy to find. Maybe I can hunt down this issue soon.

    Performa 475 Repair

    Still trying to find bad traces. Been testing in the ram area but can't find anything.

    Performa 475 Repair

    No hard drive. No video. The one time that it didn't death chime I didn't have a monitor hooked up. I put a floppy in but I couldn't hear if it was doing anything.
