Two steps forward, one backward!
My axial replacement caps arrived yesterday, so today I set about replacing them on the logic board. Sadly, the ground lead of the 470uFx16V refuses to budge and its pin stuck in the hole. I tried the following to get it free: applied heat (pencil tip, 420 degrees x 1 minute), adding extra solder blob, flux, hot air desolder gun - it still won't come loose. Trying to cheat, I soldered a replacement cap onto the stub of the ground pin, with the positive pin correctly located through hole.
Then fired up the power and the floppy isn't working. I just get :?: , but no floppy activity occurs at all - it doesn't try to read the inserted disc.
Two questions:
1) Does this sound like my my bodge job on the 470uF cap is to blame - is it responsible for the floppy drive?. I of course intend to fix it, and have replacement 470uF's. I hope the heat hasn't damaged something.
2) How best to remove the damn ground pin on the axials?
I'm now less enthusiastic to have a go at the 220uF axial, that's for sure!
