Service manual

The 'framedrive +' line drives the frame deflection.
When no CVBS is offered to the video processor, the VA and HA pulses are switched
'off' by the HIP, and the VD and HD pulses are then generated by the PICNIC. This to
assure a stable OSD.
This also counts for the AV4 input signal (HD input). When having no signal here, we
still have a stable OSD.
