Help! Amiga 3000 video issue

[chfriend]

I used it yesterday and it was fine and today I turn it on and all I get is what's shown in the video (flashing colored bars).  The computer is still booting, but I can't see anything on the screen.  I've tried reseating all of the chips on the motherboard and removing the Cybervision 64 card but no luck.

The Cybervision displays if I turn on my external CD-drive and stop the CDFS error from appearing, so it's apparently an Amber problem.  Any ideas what to check first?

It starts clearing up after the machine has been on for a couple of minutes.  I actually have to power the monitor off and on as it clears to get it to resync.  I know other 3000's have this issue, any idea what components cause it?  Bad capacitor?

Edit: It doesn't stay that way, the color jumble eventually comes back.  From bringing up the monitor's control panel while it's up, I can see that it's detecting a 31KHz H / 59.9Hz V signal, which is correct.  I do not have any monitor that can accept a 15KHz signal.

I pulled the Indivision out of my 2000 and stuck it in the 3000 to get 31khz video back, but if anyone can shed any light on what might be causing this as far as caps, etc... please let me know.

I'll have the find my PLCC chip puller, maybe Amber needs a reseat.  This did not seem like the dreaded battery screen corruption, and it does occasionally work for short periods of time, some a bad Amber or failing capacitor (or heaven forbid, a bad RAM chip in the Amber circuit) seems to be the cause.

[chfriend]

Yeah, I saw that and thought capacitors.  Anyone know which ones are part of the Amber circuit?

PS:  I'm so glad I appear to have created a Doomy thread.
