Black screen on 3000

That happened to me once also. The tuning pod where it was mounted had a broken solder joint.. there is 3 points i believe where it is mounted, might wanna check that.
Do you hear the hard drive spin up? what kind of drive is it.. Maybe it needs the scsi prefs to be set up again. I had to put a boot delay of 5 secs to give spin up time for my hd. You might of lost settings when battery died? (that could be a long shot just putting it out there).  Check to see if floppy connections too are all in place. Neve know.

Check the amber chip and reseat it? have a 1084 monitor you can test it with see if it even has to do with the video display at all.  Rgb port still worked for me when my vga port went. Maybe bad ram? check that? maybe 2 meg chip and 1 meg fast and see? try with no zip ram in there first.

whats the system spec anyhow?

Do you still get video out of the composite video out?

There is no composite out. The high-end Amiga 3000 and 4000 models lacked composite output of any kind.

could use the a520 modulator and see if it works with that. I bet its the zip ram.


lost.

edit: by chance is all jumpers on motherboard in place???

check power supply maybe. See if there is a enough voltage.. dunno grasping at straws now sorry. Reset roms? swap around cia chips? never know. Any blinks at all from the caps?

edit again lol: reading here it says :"Response from caps lock key means CIA and the CPU works.[5]"
http://en.wikipedia.org/wiki/Kickstart_%28Amiga%29
So if pressing it on and off and light goes on and off does that mean the cpu still works?

Your problem happened to me last weekend to me when i replaced the battery in my a3k. I just about crapped my pants! I removed the board again after and put it back in again REAL carefully and all worked again.. I think (well at least with me) it might of been touching the case some how. Maybe poked thur the plastic shielding at the bottom maybe, not sure what to tell the truth, but it worked again. So maybe it was grounding out somewhere. Did the 6 presses of the caps and black screen. Could be the same thing?
