Sega Game Gear (faulty, needs cap kit)

I've a faulty Sega Game Gear that probably just needs a cap kit for sale.

Was gonna gut it for parts for another mod but decided someone else might want to fix it up. It's in pretty ok condition, has both battery covers and powers up for about 1 second when turned on(used to stay powered up for a few mins and play games when I last tested it a couple years ago).

Anyway, pics later but 10 Euro will make it yours and I’ll throw in a random Game Gear game.

Sold as faulty, no batteries or PSU included.

Edit:
Free game is Streets of Rage(not boxed but comes in the plastic protective shell).
