White screen of sadness

[TheGoose]

Hardware know it all-s, I summon your knowledge.

I have a an A1000 that goes through a power up like so:


1 Switch on, power LED does the typical fast blinks an A1000 does
2 Goes to a grey screen for a moment
3 Followed by a solid white screen and nothing after. (this is the sad part)

I know this indicate a CPU failure but, I have tried two CPUs and I question that they are both bad. It could be possible. One was in a known, um, incident wiring up a 1Meg insider board and the other 68K is from an 11.50 cent ebay 'win' and judging by the abuse to the case (steak knife mod anyone?) could be DOA.

So, what else could I check, swap out? What else might cause the white screen of sadness?

:cry::nervous::confused::cool:

Also note, with the keyboard, I can reboot the machine, no problem.

LOL, well it was like stabbed with a 'stake' ? Hmm, good point, I have studied the top side, nothing jumps out at me. I guess I can look at the back side tonight.

If I decide to get a 68K from ebay, I assume a 8Mhz Mac 68K would be just fine?

Found a scratch / gouge on the current one (my old one)
Looks like a squirrel with steak knife broken in...

@tone, I did that actually, it only showed a black kind of white.

@ sahf, no extra blinking, I looked for that.

Thanks you guys, I agree, after another night with the flash light and magnifier; I think the CPUs are ok.

I think something is blown up else where - the daughter board perhaps..

Also, I switch chips around to the 11.50 board, it now it will do the exact same thing, white screen. And it has no scratches. So, gotta be a short or some bit blown...
