A1200 Floppy Light not working
« on: December 11, 2006, 07:11:32 PM »
Hi all,

I have a strange problem, I have just got a standerd 1200 off ebay.
It has no hard drive no expansions etc.

It does have 3.1 ROMs.

When I got it the floppy drive would not read disks, the FD LED on the Amiga would light up but that was it.

After striping the 1200 down and rebuilding it again, the floppy drive works, but there the FD LED on the 1200 does not flash.

The floppy drive, however has a LED on it and that's working.

I have checked that all the LEDs are connected and the solder joints are OK.

The power LED is working fine...

... any ideas?

Try getting another LED and hold it across the contacts where the floppy LED connects to the LED board (make sure you get the voltage and polarity of the LED correct). If the replacement works, then the original LED is dead. If it doesn't then there is something wrong with the LED board or A1200 motherboard.

Thanks!

I have just found it, it's a dry joint on the LED :)
