did you buy this as "working"?

[AmmoJammo]

looking at the pics, I don't think it would have worked at all.

I could be wrong, but it appears there's tracks corroded completely through.

bit late now, but I would have tested it before removing the ic :p

Buy two 24 pin sockets from jaycar for 60 cents each

[AmmoJammo]

pics?

[AmmoJammo]

tin the pins on the IC to clean them

don't put massive blobs of solder on them though :p

[AmmoJammo]

Btw when looking at the pics can your trained eye see any pcb damage I need to repair?

its too hard to tell in the pics.

a lot of the tracks look discoloured, it could just be the coating on the board, or it could be the track under the coating...

[AmmoJammo]

you made an 8 second video thats 20 megs?!?!

[AmmoJammo]

the 3.1 Rom I got is DOA! :p

try cleaning the pins, or plugging and unplugging it a few times.

Mine didn't work at first either, removed and replaced, and it worked, the next day it didn't work again... did the same thing, and its worked ever since.

[AmmoJammo]

how was it actually packed? from what you've said, I take it the foam was wrapped in foil first? but it had gotten mashed in transit?

mine was just stuck in a block of foam, but fortunately worked.

[AmmoJammo]

I have a spare scsi case, not sure if its big enough though.

[AmmoJammo]

did you test the composite out before you modified it?

[AmmoJammo]

So it really didn't work :p chip could be bad?

try replacing the three electrolytic caps in a row, should be one for R,G and B

[AmmoJammo]

if that doesn't work, measure the six resistors between those capacitors and the DB23 connector, once again, 2 resistors on each of the video lines

edit: R1, R2, R3 and R9, R10, R12 I do believe.

[AmmoJammo]

47uF should be ok, or else you can swap em around and see if a different colour goes bad?

edit: data sheet has 15uF on it
