Amiga 3000 now kaput

[chfriend]

This blows.  A few months ago my Amber circuit started acting up with nothing but flashing dark blue garbage, so I put my Indivision in it from the 2000 I have.  Now it won't boot at all.  I get the Indivision screen and then nothing, no Warpengine bong, etc...  I removed the X-Surf and Cybervision boards out and still no love here.  

Any suggestions?  I get sick to my stomach when I think of how much money I have wrapped up in this computer, especially since it's the one that has a good scanner connected to it and I'll be needing the scanner shortly!

For those that missed the last thread, here is the Amber video: http://www.youtube.com/watch?v=39QbjjjYZcw

It has a Warpengine 3040 in it.  It started working again earlier but now I've put it back together again it's not working.  Caps lock stops responding after 5-6 cycles.

When it doesn't work I get nothing except the Indivision screen.  No early boot menu, no floppy, nothing.  The monitor will also blip no signal for 1-2 seconds before it gets signal back when it's not going to work.

Hmmm.  I think I may have found the issue.  Anyone know what circuit this capacitor is part of?  Unfortunately this part of the board has the green silkscreen flaked off from corrosion but from BBOAH on a Rev 8.9 board this is C190.  It's to the right of Paula.

Oh baby is this a sight for sore eyes!

I got Amber working.  I had to do some massive adjustments to the fine and course controls and I have a feeling that I will, unfortunately, be eventually pulling this apart again to replace the fine adjustment trimmer as that is what caused this whole issue to begin with.  The VC also had a cold solder joint on it as well.  I was not able to get Amber working at all until I fixed it.

It's working again.  The cap trimmer at VC470 was bad. The clock circuit will probably never work correctly on this Amiga again but the damage is pretty much secluded to the ground plane under the battery, it didn't even spread under Paula or Denise.
