My Gameboy Advance SP’s screen is really dark, it was my brothers from a long time ago. Anyway, would they be able to repair my gameboy?

To add onto the other answer, there is a large waiting period for console repairs at the SLC location (which is the only Game Changerz that is still in business currently). Last time I was at the SLC location, which was about 2 weeks ago, I overheard it was gonna take them 6 weeks for a repair on a PS2 someone had brought in. Waiting times may have changed since then but call ahead just to be sure.

The Orem location is closed now,but the 3500 and State jn SLC is open and they do repairs.
