We would like to express our sincere gratitude for your outstanding efforts in selling and servicing
Panasonic Colour Televisions.  We are convinced that you have and will continue to make your best
efforts to improve your engineering techniques, and to obtain the highest results in your daily
servicing.
We are now introducing this "Technical Guide" to assist you and make your servicing tasks easier and
more rapid.
This Technical Manual focuses on an explanation of the new circuit technology employed in the
EURO-5VP Chassis used in our Video Projection System Television.  Please see the service
manuals for details concerning the circuits and adjustment methods.
The  EURO-5VP Chassis is for a video projector, and is based on the EURO5 Chassis.

These bus lines are used for optical circuit control of
projection TV. EURO5 chassis has 3 bus line, EURO5-VP
chassis is operated by 4 bus line.
Pin No. 76
During the digital convergence mode, digital convergence
circuit is operated by SUB MPU(IC7106).
During that time, Main MPU(IC1101) is stopped by Hi
voltage applies to pin No.76  of Main MPU.
