Hi Amigalover,
I'd also suggest trying another TV. The 'greenish tint' you describe has me at a loss, but the back and white image makes me thinks it's some PAL/NTSC problem, as mentioned. Always check the simple stuff first before suspecting your Amiga. You're in Uruguay? Cool, I just sold an A500+ service manual to a guy in Uruguay.....
Good luck with getting this fixed up... and when you can, get that hard drive replaced...
