I too want to get a Canovision E808 running.
It will power up and load the tape sometimes.
I have taken the side off to watch the mechanism load the tape and could see that the lubrication had dryed out somewhat, so put a few drops of light oil, using cocktail stick.
It now loads the tape a lot better, but the main problem appears to be with the motor that drives the tape head, It is making a funny noise as if it is driven by some coggs underneath and is not engaging properly, Will to take it apart more see what is happering there..
It will run up to speed if I give the tape head a spin start with your finger.
tape will run for a short while, But no picture is visible on the screen.
