Game Gear Problem

Hi everyone!

I have a Game Gear (doh).

I almost never play it, but today when I tried I noticied one strange problem: I almost can´t hear the sound! I only can hear it if I put my ear in the speaker. Even using a headphone the sound still really "low". The last time I played it (a year or more ago) it was on perfect shape.

Someone ever had this problem?

I´m thinking about opening the GG, but before I want to know if someone ever had this problem...

It´s really strange. My GG is in perfect shape.

Akuma Matata!
No wonder theres like a million GGs going cheap on eBay. Most coming with MINT boxes, manuals and boxed games....

...Worth buying it and repairing it? Is it easy?
