Help! Amiga 3000 video issue

[Motormouth]

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.

You have a time dependent change in your video
Sounds like the capacitors to me.....

BTW, most Amiga software does not need a graphics board, and many people install one because of pure ego.

Actually I like having my graphics boards, particularly in OCS/ECS amigas.  More colors, faster, higher resolution, more possible display frequencies.  If this is ego then I guess I have an ego.  WB is so much nicer with 8bit or hicolor.

However I can see your point if you use Amiga OS 3.1 or older, use only older pre(AGA) software, and only have a 15.75 or 31.5 Khz monitor and/or play only games.
