In working on restoring my t2, i did have the issue of the bumper lights not working or back lights. That seemed to resolve itself after wiggling the 12 position connector (witch looks like it has been burnt a little).
I continued to LED the machine, after turning it on I'm missing some of the sounds.
No Arnold at all, the other sounds are still there.
Take a listen/ look at the attached video.
I also think I need a new ribbon cable (14 PIN 30" ) for the DMD, but marco's seems to be out of stock. Anther suggestions as to where to get that?
Thanks,
-Will
