Hi all,
I encountered a strange issue during/after a recap on A600 rev. 1.5.
I've not repaired so many Amigas but fixed some 500's with minor problems.
This machine had floppy drive issue and no video on composite.
No video was caused by Z222 and I bypassed it just to make sure it works, floppy drive was recapped and now looks working' (not fully tested yet), so there's the main A600 plague, bad caps and some corroded traces.
Initially the machine worked ok, after I replaced all the capacitors (found about 4-5 ceramic caps on the 5V line in nearly short too and replaced them!) and removed Paula to check traces under the chip (some of them were "blacky") I putted all back and powered on the A600 with some ugly glitches on the half-down screen like in attached pictures.
For older machines like A500/500+ I used the Test Disk floppy but in this case, after loading the Test Disk, I could only see garbages on the screen, so I bought a DiagROM and did some tests. Most of all seems working ok, except option 1, 2, 3 in Graphics tests: it causes glitches, empty screen or no video at all. RAM, CIA, IRQ are ok, sound tests are ok.
I also tried disabling and removing Paula again (thinking about some wrong soldering or other) but nothing changed.

I've seen around that this kind of problems is caused by a bad Agnus, but I don't understand how it could be correlated the work I did.
Before starting messing anymore around and buying replacements there is some others checks and tests I can do?

Thanks in advance.

Hey Coyote!

ACME was the best board in Houston, and one of the best AMIGA boards in the world..

Back in the 90s, If you had to choose between a dial-up internet connection (by the hour back in those days) or an elite-user subscription to ACME, you chose ACME hands down.

Everyone, Drew also ran the local AMIGA User group in Clear Lake City (just south of Houston). He's a Houston area Amiga legend!

Hi Dew,
Welcome to Amiga.org and thanks for posting and sharing your background. Hopefully there are some members of this forum who were involved with your previous work.

Just on your A4000, check the battery hasn't leaked.

Just wanted to check in and say Hello.   So, _hello!  The Amiga systems shaped my life in a great many ways.  I used to run a 10 line Amiga BBS (skyline  based) in the Houston area between 1989 and 2001 (having apx. 2,500 members at one point).  I was also the president of Club Amiga with 3 chapters around the Houston area around that same time. I BELIEVE we had around 1,500 members at its height.  To this day, the Amiga and the BBS still influence my life on a daily basis, though I have not turned on my Amiga 4000 that was running the board in a few years. It did work, and had the cybervision 64 running the display.  Anyway, hope everyone is well and still enjoy the Amiga life. -- Drew
