Amiga 3000 White Screen
« on: December 18, 2012, 08:05:16 PM »
Hey all,

Well i picked up a 3k last night and of course it had battery leakage.  Was resetting and getting getting yellow screen.  

I took it all apart, removed the battery, cleaned the area, fixed some traces, reseated all of chips, and now it boots to a white screen.

The two mouse button on boot doesnt work and i can press caps lock ~14 times before it stops responding.

It looks like it has the 1.4 kickstart roms, and i have seen people say their 3k will boot to white if the HD is not attached, or DF0 not present.  The hard drive may be bad though, i have tried with/without the floppy.

I tried:
-Switching the jumper for tick/vsync
-With/without Zorro riser
-31k/15k out
-31k enable/disable
-pal/ntsc jumper
-every combo of above

I have read that 27c400's are drop in eprom replacements for the kickstart roms?  

I think i have some lying around i can try so i can upgrade to a newer kickstart.

Any suggestions?
