Hardware GBC Hardware problems

[NoSnake221]

I got a lil' problem here... today I bought a Gameboy Color on a flea market for 5 bucks, but when I got home and I tested it with a GBC cart, there was no sound and even tho the console turned on fine, the image showed with incorrect colors (Mostly a distorted mix of black and white instead of the colors it should be showing) I got a multimeter around for doing some tests, but I don't have a clue about what could be wrong.. Got any ideas?

The first things I would do is clean the cartridge port with IPA then visually inspect the board for bad caps, dodgy solder joints, etc.

Here are some pictures of the screen I took while having the Donkey Kong Country cartridge inserted:

Also, the text that should say "Nintendo" is all glitched when booting the console with no cartridge inserted:

Already cleaned the port, I'll check the board. Thanks
