Title: HELP! I think I blew up my A1200!
Post by: Martin_Lee on September 18, 2005, 10:05:20 PM

Ive got an IDE splitter cable going to the HD and a CD drive but I think a couple of wires touched eachother and sparked and now when I turn on my Amiga the screen is blank and the HD makes weird noises.
ive tried it without the HD and the floppy clicks but the screen is dead!

HELP!

I don't think anything can be done.
If you blew out some chip or the video circuits the easiest is to replace the motherboard and be more carefull next time.

any advice on how I might find out what is dead? or what I should do next? so you think i should just get a new mobo?

this completely sucks I was so close to finishing it all!

hopefully the HD and 3.1 ROMS will be ok

Ouch!  Sorry to hear it, but it looks like you'll need a new motherboard.  Not getting anything on the screen is a bad sign.

I knew someone who bought an IDE interface years ago and accidentally hooked it up the wrong way.  There was a slight fizz noise then loads of black smoke.  Thankfully it was only the IDE interface that was blown.  Absolutely nothing else was damaged at all.  Except his confidence ;-)

Im so crap at electronics!!!

I think the two power wires for the cd drive touched and maybe the wire that was earthing it

You've likely shorted out one of the two cia controllers.
They are surface mount, hard to replace and these days
hard to find replacements. The price of a replacement
MB seems reasonable, good luck in your search.

does the floppy click constantly or only once when Amiga is turned on? If it clicks all the time, maybe its not so badly destroyed (hopefully)
in any case, don't throw the motherboard away, you might need it one day for parts

Hopefully the ROMs are OK. If so the price of replacement motherboard from E Bay dealer is quite reasonable and you don't have the lottery of bidding !!

You could also try AmigaKit but might baulk at their price.

I've actually got a1200 with 3.1 roms that isn't doing anything that i was  planning on putting on eBay, I'll let you know when I do, or I may be open to offers.

thanks for all the responses everyone

the floppy just clicks once..


Indeed I am looking for a new mobo, preferably REV 1.
Thanks detz, give me a PM :)

I have a very nice Wacom Graphire 2 worth £99 which I might be willing to swop for nice things maybe

Amiga Kit obviously keep a keen eye on these forums and have subsequently reduced the price of a replacement motherboard. Considering the Amiga market this is good news and shows they take the Amiga and it's customers seriously.  :-)
