Turbo Grafx Question

[vintagegamecrazy]

I have a Grafx and a Duo and both need repair, the grafx has a loose av output and the duo just shuts off now and then and won't turn on for a while. question is what size security bit do I need to open these? Can I purchase one on the bay from the nes section or do I need another one?

Thanks

Use the melted ballpoint pen method.

4.5 MM Gamebit can be used to open up the TG-16, this is the same style screw that is used on Genesis cartridges and the SNES console. Might as well go get a 3.8 and 4.5 MM bit set if you don't have them already.
