Help with game gear, should I try to repair it?

[Gocha]

Hey guys, I saw a cheap game gear here in my country, as the following picture shows it is not working, but it turns on.
My question is, is this a "usual" game gear problem? I'm thinking on buying it if there is a way to repair it, I'm not an expert at repairing at all, but I've done some jobs before on almost every retro console I own from NES to sega saturn, so I know basic soldering, reflowing, cleaning, instaling simple chips, etc.
I know there are a lot of problems comming form the capacitors on this devices, but I have no idea if someone have seen this particular kind of image with the caps problem.

Thanks in advance, here is the picture the seller uploaded.
