Blizzard PPC 603/060 board issue

[kbjunkie]

Hi all,

I picked up a dead (black screen) PPC 603/060 board for my A1200 that I;m trying to get repaired.

When looking at the board powered up, I noticed the fan wasn't spinning so had a look at the connector on the board and noticed a repair bodge - I wondered if anyone recognises it as such or is this a case of something killed the traces (over current) and someone else has had a go at repairing it?

If some one with one of these boards can take a hires pic of the same area as in my attached pics from a good board, I would really appreciate it!

Cheers,

Mark.

That looks .... errrr .... terrible

I got mine stored in a box somewhere, I found this on the net, maybe it helps already ...

If I get around to it, I´ll search for the box and take a photo of mine at the weekend.

Thanks for that pic - I'd already found that last night and it does help a little but a hires pic would be much better.

I measured the voltage across the fan header last night and it appears worse than I thought. If I measure across the header, there's no voltage. If I measure from another ground point to either pin on the fan header, I get 4.7v on each pin.. That means that the ground on the fan header has almost +5v across it..

Must be something to do with the bodge repair.

I don't suppose you have a schematic for the card at all or know where I might find one?

Thanks,

Mark.

No, sadly not (were they ever released ???) ...

I would really appreciate that, just when you have time though :-)

I'm guessing not.. I've looked all over the place without any success. I'm hoping that with a decent high res picture of the area on a good board and my microscope, I can work out what do do to repair the mess.

Thanks again, I really appreciate anything you can do :-)

Best,

Mark.

Didn't Chucky make one to prove the ground planes were missing from the "new Phase5' boards 5 years ago or something?

I have a BPPC603 but with 040 on it, can make a photo but not sure if it is the same...

Was that for a 1260 though - not the PPC?

I'm not sure - would it be a great trouble to have a look for me if you can?

I would appreciate it immensely!

Thanks,

Mark.

Ah yes, the misadventures of Phake5…
Almost forgot about that scam

Got some spare time in my home office today and found it

That´s the best my smartphone can do, hope it´s useful ... I´ve put them into ZIP and put it here (too big for an attachment) :

Fantastic! That looks like it will do nicely!

Thanks so much, really appreciate it :-)

Now to go see what has been done to the card I have

Thanks,
