Title: A3000 died
Post by: Bokasa on August 30, 2013, 01:31:46 PM
Black screen, power led light, caps lock led not light (keyboard are ok, and caps lock led light at other amigas). Any suggestion?

If the kybrd is good and caps wont light it could be the CPU.

Check the capacitors near the motherboard power plug. I had a similar experience with my A3K.

Try re-seating the daughterboard, sometimes after time it flakes out, or the contacts get corroded and re-seating or cleaning with alcohol and an eraser will clear it up, if that doesn't work, it can join my A3000 and my A4000 that I am still working on (slowly, well very slowly) aw heck, in storage for parts (I bought both from ebay, dead don't work very cheap) but since my originals work quite well, haven't panicked yet.

Sometimes if you just plugged in a new card into the daughter board, then it moved it and the Amiga 3000 blanks out, it won't run without the daughter board, or so I was told by my repair guy from Commodore. Got to believe him because Dave was hardly ever wrong. ( and no it wasn't Dave Haynie, I only trust good repairmen, not some freaking college boy engineer who thinks he is in charge of the choo choo).

Oh did I mention check you power supply and try re-seating the plugs to the motherboard, and check the power plug, sometimes you think they are in but only the rubber end is holding it in.

and

If that doesn't work, make sure no one kicked out the plug in the wall, (had that happen to me once, Took me 4 hours to figure out what was wrong. Re-seat the CPU card, if you are using one. Check all the simple stuff first. What where you doing when it went black? re do the events.

Might be obvious but have you tried both the video outputs on you A3000?  Any hard drive activity at all?  Agree with the above - alcohol & reseating!  ;)

+1 to what smerf said.

The daughter board in my A3K is really flaky too and needs reseating every now and then when it shows the same symptoms you are having with yours.

Check for battery leak if you have one.
