Gary, Can you post a photo of the screen so we can make determine whether this is spot on to what Trag said? In the mean time, I'll verify this with my own SE/30, even if it's no…

Thanks JDW for reply: To simply my request for answer re focus problem, I didn't state full story. My SE 30 motherboard failed in May, and I purchased a used replacement from "Ne…

Your advice was spot on! I removed the battery and actually booted without it once and then put the battery back in and booted again. It booted fine both times. This one has a n…

Pulling the logic board and replacing caps should not affect your screen focus at all. I should know since I have yanked out my motherboard and put it back in dozens of times with…

Can you double check whether you get a mouse arrow in the top left-hand corner of the screen or if you even get a startup tone when you turn it on? Another culprit could be that t…

I agree with JDW. Worst case, a new wire to replace the trace would be installed if the original pads and trace are deteriorated beyond salvaging. Are you going to perform the re…

Should be fixed now...

I'm quoting JDW from an older post he had on AppleFritter: "I have also read about replacing the bourns chip (RP2), but I don't have one handy and I honestly do not see the logic …

After examining your photos, it is clear that your analog board is in good shape. But it is also clear your motherboard is in bad shape, especially in the area of C9. You not onl…

PM sent!

TheNixer, It sounds like you have a problem with the network filter (RP2) on the SE/30 logic board. So you are correct. Referring this info to the website you linked in your las…

Here are some pictures of the boards and the ram. Let me know what you think. The last two pics look like some of the caps are bad. http://yfrog.com/izpc27011550j http://yfrog.co…

First thought: mosey over to cubeowner.com and browse the video card forum. Second, that's the way a GPU that's been running hot seems to die. Unless you had a fan on that 7500, it…

I have experienced SimasiMac on multiple SE/30 logic boards. SimasiMac in its truest form is a set of HORIZONTAL bars that are very clean with no stray pixels here and there. The…

SemperFi94, THAT is a classic symptom of what is called "Simasimac", or "Zebra-like pattern". I refer you to the following link below: http://www.biwa.ne.jp/~shamada/fullmac/rep…

Yep, I got the Centronics cable, it plugged right into the back of the CD-ROM Drive. Thanks for the reminder.

make sure, that fits onto a cable to change it (which is fine if you have a 50 pin <-> 50 pin centroncis cable)

Yeah I did some research shortly after I posted the question. You are correct it's a Centronics. I found the adapter here. http://www.computercablesource.com/scsi-adapter-centroni…

I need a 50 to 25pin adapter for the cord to plug it into my Macintosh Color Classic. I ordered one and got it today but its a tiny 50pin on the adapter and not the large wide 50 p…

my problem is at C13. i am looking in that general area to see where to scrape exactly with the idea of exposing the correct copper wire. Click to expand... I don't have any SE…

Hi Jason, I responded to your email a few minutes ago. I see that JDW gave you basically the same advice I did, but in better detail. You didn't mention the reverse polarity pro…

a big thanks to JDW for such a thorough reply. just to be clear i am *not* that dexterous with a soldering tool. in fact, this whole process of cap replacement is new to me. my pr…

I have never "partially recapped" a board and then tested it. So I cannot speak from experience in that regard. But what I can say is that if you have the caps properly oriented …

i have 220uf 35v for 220uf 16v can i use this ? and the surface pads have come up off the board for one of them. how will i make a good connection now for that capacitor?
