Twin famicom AN-505-BK Grey screen only on disk mode

Post by sydsydsyd »

Today I was trying to play with disk mode and I don't have the classic image of Mario and Luigi jumping anymore, I get a gray screen. :?

Some time ago I closed the pins of the socket because it was very loose and I think that the pins that are facing each other were short-circuiting when there is no cassette placed in the socket. :oops:

I think this may have burned a chip on the floppy side of the motherboard. If that were the case, which part of the PCB (which chips) should I check? Is there some kind of fuse or logic gate that could blow due to what you mention? Thank you very much.

I hope this will help to the entire community to solve this problem, cuz I was searching a lot on the internet and couldn't find anyone mentioning that this could be the cause of this grey screen issue on disk mode.
