Glitchy Turbo Grafx 16

AsmikAce

Hello everyone. I found a Turbo Grafix 16 in a barn that you can read on a post on Collector Corner and I am in the middle of getting it all clean and running. However, it powers on but have messed up graphics yet still plays the correct music and runs, kind of like when a NES games doesn't have the proper contacts with the NES.  Any suggestions in what to do beside continue cleaning the system?

Heh I've never seen a TG16 do that before. But I've also never seen a console that dirty

Keep cleaning I'd suspect and I would presume you cleaned the card slot anyway, but if not id wrap the hucard with a coffee fliter with a little and insert it and remove it a few times might hit with a little isopropyl on the filter and see it improves any, which I don't know how your running the video (rf or booster) but id look about there as well. I used a nes rf on mine which mine still has garbled graphics but kinda tweeking with the rf it improved drastically so something in the module is loose, have a pc engine now so I never fixed the t-16 but had plans using the pins in the back to make a KO booster with rca cables.



Dat be muh inputs, pretty sure someone with better knowledge will chime in soon enough.

I want to stress is that part of the graphics are replace with digits or other sprites, not poor RF connection.

It could be the game, have you tried another one? Open the console and give it a good clean, sometimes residue can short traces, also inspect the board closely for broken traces.

Sounds like the program is loading but not the graphics, I would blame the card edge connection. Disassemble the system completely, desoldering the shielding from the motherboard, and clean the contacts with an acid brush and 91% alcohol.
