Sega Game Gear repair

Hello, I was wounder if anyone knows of a good place to send a Game Gear to be repaired or refurbished? I just got a very rare but unpopular Mega Man game gear game and bought a game gear at the same time that was in great condition. Unfortunately I did not know the all Sega hardware up to the Dreamcast are very susceptible to heat damage. I bought it during the summer and after reading about Sega hardware heat problems I am sure that the summer heat damaged the game gear. Please help, I have been waiting years to play this Mega Man game gear game!

first look around computer repair places. a few computer places repair other things than pc.
