I made some smoke on A500...

So I killed her! Now, that wasn't very funny at all. First I managed to rescue this one A500, when I noticed it had cracked soldering on motherboard where sqaure power socket attached, the disk drive didn't work because of that. After repair it worked fine.

But now I busted whole thing, when tried my "newly power hacked" (used ATX to power both) A590 on this poor thing, before I mated it to A1k. By mistake I din't doublecheck everything and it shorted somewhere where I put extra wires underneath! Well lucky me, A590 was fine, but not so A500. Nasty smelling smoke protruded under the case and it didn't power up anymore.

So after opening cover I noticed smoke traces under RF-shield where LF1 "line filter" sits, right behind that sqare power socket! I think fault is there, no power goes to machine. So what do you think, can I get that component somewhere to try repair or should I use this machine for parts?

 Here is pix of this component  (not my burned one)--->

BTW... Now A590 works fine with A1000, only using Amiga power supply, no externals.

It's a cheap enough part to replace, but I have a feeling other things may have burnt too.

But can I buy this part somewhere? Is it standard electronic component or A500 specific? Ofcourse these machines are unexpensive here, but still I must try a rescue once more.

Oh, I guess you are right about that. The case was pretty yellowed anyway and it was Rev.5 mobo, so maybe I make this my spare parts machine, at least it has working keyboard and a floppy drive to make other Amigas live

Dare I say you can fix a yellowing case...http://retr0bright.wikispaces.com/

I hate chemistry! With my luck I end up being blinded or something... But it would be really cool to test and see the results personally. Have you tried?

On MBS topic; yes lots of it escaped this computer that day! Without in depth knowledge of electronics I think I'll take it as a lesson to myself.
