White horizontal line with black screen but sometimes has audio.

Hello all,

Just found my old Game Gear and games but when I turn it on I see a white line (sometimes 3) going horizontally across the screen. I cleaned the cartridge and port in the console where the carts go and I was able to hear the game playing but the white line was still there with a black screen. The backlight works but idk if its my screen that I need to replace along with all the capacitors.

Do you guys have any recommendations on what I should get to replace all the capacitors and any suggestions on a replacement LCD for it?

Thanks!
