snes console with video problem F/S

[Quintracker]

I've got an snes that I can't even try to fix cause I don't have the screw bit. The video problem is it's like a scrambled signal or something and it's in black and white. I thought one possible problem could be the metal shielding, but I really don't know. Console only, no cords or nothing.

I'll sell it cheap or make a trade.
