Problems with PSU input of my A600

[balrogsoft]

Hi, i have three A600 mother boards, all with problems, one don't boot at all, the rom screen don't appear, for this reason i bought a second A600 motherboard, but it have problems with PSU input, if i move the PSU connector, my A600 suddenly power off, then i bought a third motherboard, it was working perfectly two months, but last week, my A600 power off without touch it, and it's very difficult to have it working, only work if i press down the PSU connector a lot. Then i decided to put the second motherboard, that have similar problems but work better, but if i pull up psu connector, my A600 suddenly power off.

It seems that A600 have a lot of problems with PSU input, i have two Amiga computers (A500, A1200) a lot of years and never had problems with PSU input. Somebody had similar problems? how did you solve it?

It might be worth checking the underneath of the board for dry-joints.

I was wondering why my A1200 floppy drive LED doesnt work and I just noticed that all 4 legs have come loose off the PCB.  Once I find the soldering iron I will try to reattach it.  The same thing can happen to anything that has been soldered on a PCB especially over time.

Generally if it IS a dry joint you just have to reheat the solder on each leg so that it makes a proper connection.  However if its actually torn off the PCB you might have to rewire it to somewhere else on the PCB to repair the problem.

If its the power connector itself thats gone funny you might be able to swap it off one of the other A600s you have, if you are better at soldering than I am.  :roll:
