Atari 1040ST Not Booting

[Mr Spatula]

Recently, i got an Atari 1040ST with the box, monitor, 2 different MIDI attachments, and tons of software and games. The first time i powered it on after i got it, it worked just fine. Then it crashed and gave me two bombs. So i restarted the system and got nothing but garbled lines and about eleven bombs. Now it wont do anything else. It doesn't even try to read the disk drive.

 

I'm a complete noob when it comes to Atari systems, so any help is appreciated.

Does this happen when you turn on the ST without a disk in the drive?

Yes, but i have found the problem. Some kind of brown rot on the bottom of the mainboard.

[Mr Spatula]

Well, i cleaned it up, but it still doesn't work. Any Ideas?

Universal 4" atari drop. Or reseat all socketted chips.

4"? Hmm, I always dropped mine from low-lying buildings, worked fine. Bonus points if you hit Amiga users on the way down.

All chips have been reseated. Same problem

If you've reseated all the chips you can, checked and cleaned all connections, and

you're using floppy's that you know are good, the next thing I'd be looking at is

the power supply. Any chance you've got a known good unit you could swap out with?

Unfortunatly, i don't. What's the voltage output of the power supply?

might be a bad ram chip somewhere
