Unhappy Distorted image with Commodore 128

I've recently opened my C128 to try fixing some problems after months of disuse. Some keys didn't work, the spacebar missed the springs so it was constantly pressed and the computer didn't load my programs from cassette after I recorded them (all in 128 mode). I've fixed the spacebar with a spring I took from a pen, cut in two and placed them in the right places. I've also found out that the keyboard wasn't plugged in correctly, wich could be the reason some keys didn't work. I still don't know why it didn't read my programs after I recorded them, since the play/record head of the datassette was aligned. Now that I've booted my C128, it displays this weird distorted image, which is mostly green and red, accompanied by a very loud humming sound. What could be the problem? Perhaps I've reinstalled the heat sink incorrectly after cleaning the motherboard? Could it be the power supply damaging the computer? Or even just a bad cable (I've used an 8-pin DIN to scart)?
