Amiga 4000 Blue Screen of Death
« on: July 15, 2004, 02:26:34 PM »
Hi Guys

After over 10 years repairing/selling Amigas I came across an early startup error screen i've never seen.

We have an A4000D here that when powered on gives a BLUE SCREEN and stops there... any idea what this means.

The commodore docs say blue = custom chips error but the machine was working fine before. I did notice there was  a soldered lead from a capacitor to a leg on a small surface mount chip near the battery that came out..

Battery leakage?

I once had a fault with my A1200 which gave the display a blue tint
(but not a complete blue).

I sent it for repair with Wizard Developments (Now Computer! if they
still exist) and was told it was a failed VideoDAC.

I also heard Budgie mentioned I think.

Wiggling the RF lead about would cause the display to come back to
full colour which made me think it was just a socket loose.

Another weird colour thing I got was with my old Blizzard 1230-IV. I
was told the old Quantum Daytona GO-DRIVE brand was incompatible with
the 2.5" IDE interface and so it produced a red, flashing screen.
Indicating possibly the ROM was there and then disappearing.

:-D :-D :-D

Nice colours on the Blizzard 1260 bootup though, a sort of vertical
rainbow flicker of all the colours.

What is the PowerPC boot colour?

FYI

All the Phase 5 high end accelerators show this "rainbow" effect during startup..
