as you can see the output is garbage

I recently saw a sinclair commodore 64 on eBay also, I think its keyword spamming or something

Hard to tell from the picture, but the first thing I would try is to insert a game cartridge. If that works, I would have a look at the Basic ROM.

Regarding Sinclair C64, I tend to remember some homebrew hack where a person had reused a C64 case, painted it black with rainbow stripes and inserted a ZX Sinclair motherboard. I might misremember parts of the setup, but it was only some years ago. Given the number of 3rd party keyboard available for the Spectrum, I would suppose people already back in the days tried hacks like this if you had a broken VIC or C64 to gut.

Either it's a bad connection to the TV, or the C64 threw up random characters / pixels on the screen. Difficult to tell.

Looks like bad DRAM, VIC-II, or PLA chip.
