040, possible to repair?

[tokyoracer]

I received a non working 040 in a BIG lot of Amiga stuff.

Symptoms are very simple really, it will not display anything other then a blank screen (but the AV3 icon on the TV is always on so doesn't even seem to display anything what-so-ever). The fan powers up ok and apart from the battery which isn't in good shape it all looks ok physically.

I have taken a couple of detailed scans if anyone wants to see...

Was rather hoping I wouldn't need to remove my very complex 030 card, I'l get to it shortly and let you know how it does.

Ok I tested it and the same result on the other 1200. I was wrong about the TV, it does boot but only a blank screen. I received an e-mail with a link to an American site who dedicate themselves to repair Amiga and Atari stuff. I'd rather see if it can be sorted easily first before I start sending it off but any other tips and/or ideas would be much appreciated.

Sorry but allot of the replies are a bit new to me. I'm not that well up on technical Amiga language. :-(  :-)

If that site is in Beaverton, Oregon, then stay far, far, far away.

The fan works fine, but i'm not sure if this chip is removeable as there is no plastic mount I can see on the side of the card.

[tokyoracer]

So should I remove all of the jumpers on the cars as-well as the RAM card?

[tokyoracer]

Sorry if this is a dumb question but what one is the ram jumper?

[tokyoracer]

Nah, I removed it and the card but it's still the same outcome.  :-(

The horizontal pins are marked (left to right): 060, CLK, 040.

Vertical (left to right): RAM, SCSI, 060.

^ If that helps? It is back to how it was pictured.

I'm testing it on all sorts of 1200's. Well 3 different machines. I don't yet have the heart to dismantle all the models as it's allot of effort. I'm guessing if it doesn't work on any of them then it's the acc. at fault I'm guessing.

I might do it a little later on if it will really make a difference.

[tokyoracer]

I got 3.1 but one of the 1200's I tested it on has 3.0 and was exacly the same.

[tokyoracer]

Links to repair sites would be much appreciated. :-)

[tokyoracer]

Thanks for that link. It all looks promising but i'm not sure what contacts to clean, how or what to use.

[tokyoracer]

Sent PM. =)

Sorry to double post, first real action now and will be sent off to Sweden and hopefully it is a CPU issue. If not then the troubleshooting will bigin... Again. >.< Which I hope won't happen.

Fingers crossed & thanks PG! :-)

[tokyoracer]

Sorry to triple post but just to alert people it is in for a replacement CPU at the mo. Hopefully this is the solution. :-)
