Title: I fear I may have neglected my miggy a stage too far.
Post by: Karlos on September 24, 2008, 12:42:34 PM

Now my main 1200T doesn't boot at all.

I have decided to strip it down and give it a damn good cleaning as it was choked with dust.

Perhaps it may recover but I'm not hopeful.

Shame on me :-(

I'm sure it'll come back to life once you've given it some TLC  :-)

Don't give up!

Agree with TLC.  Also some CIR may help.

- C: Clean it
- I: Inspect (capacitors, traces, battery leak etc)
- R: Reseat (socketed chips)

Usually does the trick.  A multimeter may come in handy to check the PSU.

There's a lot of dust under the BlizzardPPC heatsink. The thing is I haven't actually used it for ages and I cleaned it out then. Quite strange, really.

I'm loaded with cold myself at the moment so I need TLC as badly as the miggy does but I'll see what comes of a good CIR session.

Check out that your PSU outputs +5v correctly too

My system lives again, almost. It recognises the 040 on the PPC board and naught else.

Last time it got like this I had to reflash it.

Clearly, the PPC isn't mil-spec! ;-)

Seriously, though; I'm no expert on the PPC cards, but don't they have some kind of reset? If a flash resolves the problem, then I doubt placing the same code on the ROM's again will resolve the problem.
What else does a re-flash do, besides the re-flashing?

It scares the living daylights out of the thing, as Karlos stands there flapping his coat open/closed/open/closed and the poor little computer contemplates the horrible events about to follow...  :lol:

I never knew an little used machine could accumulate so much dust.

It's been stripped, cleaned, had anything that could be reseated reseated, the PSU has been checked, capacitors inspected (no leaky or bulging ones found yet).

All in all it was in OK shape apart from the dust, a scarily large amount of which was in the PPC card's heatsink.

I have since managed to get it booted, though it refused to do so until I flashed the PPC card.

I wonder just how many years are left in the old girl now :-/
