2nd hand A1200, Amiga keys not working

[MarkAshley]

I've bought an A1200 from eBay and the Amiga keys are not working. I haven't found any other keys that don't work. It's extremely annoying as I can't reboot the Amiga, I have to power it off and back on again.

I have opened up the case and there are some brown stains on the bottom of the casing. Looks like something may have been spilt. I can't see any stains on the keyboard itself or the motherboard, so I think it's ok.

Has anybody had any luck repairing faults like this?

Thanks
Mark

I do plan on towerising my Amiga at some point, but £150 for a D-Box is out of my budget at the moment, especially as I have just bought a Blizzard 040. Are there any cheaper tower alternatives?
