EURO 4 Chassis
Video from the tuner is fed to the base of transistors Q104 and Q105 this video signal then takes
two paths, the video signal is buffered and output on the emitter of Q104.The signal is then fed to
pin 61 of the VDP IC601 through C624.
The video signal is also buffered by Q105 and is output on the emitter.The video signal is then
output at pin 19 of AV1
Transistors Q253 and Q254 were originally intended as audio mute transistors,but are no longer
included on the Euro 4 chassis.
Video from pin 59 VDP IC601 is fed out through E15 pin 6 to the H board at connector H1 pin 6,
goes through emitter follower transistor Q3402, and is input at pin 8 of the AV switching IC IC3401.
The signal is then output at pin 8 of the AV switching IC back through H1 pin 8 to E15 pin 8 onto
the base of buffer transistor Q3001. The video signal is output from the emitter of Q3001 throug|
