the picture is black with some running horizontal stripes
aiming to a bright light, no difference, still black and running both on camtube and tv
date and time on camtube is ok, not on tv (not visible)
when tape inserted, if tape contains picture, its visible with little distortion
focus is moving at front

no schematic diagram available

anyone tips or schematic?

Might you want to check the CCD flex and connector.
The lens must move at the front when you power on the camera.
