Probably just a loose connection on the video cable.

Yeah check your connections… However, you realty need to provide more details/info, else we’re just guessing…

try cleaning the drum head with soft lint free cloth.
carefull you can easily damage it .
apply little alcohol on a clean cotton soft cloth and lightly touch the drum head gaps and rotate it with hand.
usually picture fails when head gap is dirty.
sound comes ok means electronics is fine
be sure to clean the control head also
