TASMIN EURO 4 Chassis Amendments Q104, Q105 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 Q253, Q254 Transistors Q253 and Q254 were originally intended as audio mute transistors,but are no longer included on the Euro 4 chassis. Q3001 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 through to pin 19 of AV2 video out. SCHEMATIC Contents DIAGRAM TASMIN EURO 4 Chassis Amendments Q1108 A vertical sync pulse is fed to the base of buffer transistor Q1108, the sync pulse is then output at the emitter, here the sync pulse is split, it goes one way to the vertical protection circuitry and the other to pin 47 of the microprocessor IC1101 Q3209 Video from AV2 is input to the M board via pin 6 of connector M3. The video signal is fed to the emitter of Q3208 and goes through the emitter collector junction of the transistor , the signal is then output at the collector to the base of buffer transistor Q3209. The video signal is then fed out from the emitter of Q3209 back to connector M3 to the H board for AV switching. SCHEMATIC Contents DIAGRAM
