I have 3 game gears , 1 working, 2nd one fixed, and a third that I used to practice on for soldering. A while back I broke off some tiny black piece in section C57. I don't know what they are, maybe some type of resistors, but I need to replace them in order for the system to work. The system still works, it's just the video that is dim. No one ever talks about these parts anywhere, only capacitors. One more thing, I also ripped the contacts off in section C54 capacitor by accident since it's just a practice board, but I managed to get a knife and scrape off a bit of the board to reveal the line it follows as told to me by another member. Can someone please explain to me what is in section C57 and do you really need those?

Tried asking the forum at smspower.org?
There's probably a few people there who extensively hack 8-bit Sega consoles.

C57 is a surface mount capacitor, I doubt that damage to that would cause the problem. When C54 or something connected to it goes bad you get the poor contrast problem. BTW on mine C57 is a tiny grey component, take a close look at the resistor R47 next to it to the right and the transistor Q11. Here is an ascii rendition of it. I assume yours is a VA1 unit.
