Service Service Service W-V0 0-0 Product Service Group udio Service Information lready published Service Informations: ORRTION TO SRVI MNUL elow are corrections to the circuit diagram parts list: OMI OR * elete 0 and (Not required) k % 0,W k % 0,W HNGS URING PROUTION MPG OR * rom wk0 onwards a new pt. board is introduced to solve MP playback noise (see newsletter SNL00.0.) problem by adding: 00 00 k % 0,W 00 00 0k % 0,W 0 00 0 W Note: 0 base-emitter is shorted to function like a diode. * rom wk0 onwards a new Servo I (software version ) is introduced to improve playability. The new I is recognized by printing mark "MPG0S0" and is available under service code: 0 * rom wk0 onwards the Video Processor I 0 is replaced by S00L. ecause of this replacement the following changes are made to: - adapt supply voltage from, to,v - adapt audio output level to 0mV 0 00 0V 00 0V 00 0V 00 0V 0 0 k % 0,W 0 0 k % 0,W 0 0 k % 0,W 0 0 k % 0,W 0 0 k % 0,W 0 0 k % 0,W 0 0 k % 0,W 0 0 k % 0,W 0 S0L LT * rom wk0 onwards a new pt. board is introduced to solve picture jerking cracking noise problem by adding: p 0V NPO 00 Note: The pt. board is not published because it has minor track shifting to prevent short-circuit to MPG shield casing. New pt board layouts circuits are enclosed. RONT OR * rom production wk0 onwards a mask version of the ront microprocessor I0 is introduced due to deletion of the ue/review features. The service code for the equivalent OTP versions read: 0 000 0 OTP version for W-V0 0 000 00 OTP version for W-V0 It is very important that these OTPs are used only on sets without ue/review feature! The mask Is used in production can be recognized by their printing mark: - V0S0 for W-V0 and - V0S0 for W-V0 T OR * rom production wk0 onwards the following changes are made to improve current handling reliability: 0 0 PMT0 0 0 PMT0 0 0 PMT0 000-0 - 0 00
