The C64, returns.

Phew it wasn't a fault with the C64 it was a faulty TV.  The new TV doesn't show the tearing in the top right corner after a few minutes use.

Speaking of the video output on a C64.

Thanks for posting this.   

I didn't have any luck with the LumaFix64 either, and it bent the pins on the old VIC II chip because the fit was so tight, so I had to carefully bend them back.
