Commodore VIC-20 - Video Adjustment Notes

THE COMMODORE VIC-20 CAN BE CONNECTED TO A MODERN TV / MONITOR WITH COMPOSITE VIDEO. COMPOSITE VIDEO IS THE STANDARD VIDEO INPUT ON YOUR TV (THE YELLOW RCA PHONO JACK LABELED VIDEO IN).

TAKE CARE WHEN MAKING ADJUSTMENT ON LIVE CIRCUITS TO PROTECT YOU AND YOUR VIC-20. THIS ADJUSTMENT IS NOT REQUIRED ON C-64 MACHINES.



TECH TIP

MANY ELECTRICAL ADJUSTMENTS PERFORMED ON VIDEO CIRCUITS IN PARTICULAR ARE PERFORMED LIVE WHILE THE MACHINE IS POWERED ON. ITS BEST TO USE PLASTIC PRECISION SCREWDRIVERS DESIGNED FOR WORKING ON LIVE CIRCUITS WHEN PERFORMING THESE TYPES OF ADJUSTMENTS.


VIC-20 - VIDEO ADJUSTMENT FOR COLOUR CORRECTION

The VIC-20 video output is optimized for use with an external RF modulator and may require adjustment for colour correction. The colour maybe adjusted through two tiny potentiometers located in the video circuit inside the VIC-20. Please see the adjustment photo.

You may have to remove the metal RF Shielding to gain access to the potentiometers. Please see the enlarged JPEG photo below to see a nice view of the the adjustment locations.
