CORRECTION TO SERVICE MANUAL Below are corrections to the circuit diagram & parts list: COMBI BOARD * Delete 2405 and 3456 (Not required) 3681 4822 116 52276 3k3 5% 0,5W 3682 4822 116 52276 3k3 5% 0,5W CHANGES DURING PRODUCTION MPEG BOARD * From wk0134 onwards a new pt. 2 board is introduced to solve MP3 playback noise (see newsletter SNL2001.03.13) problem by adding: 3234 3235 7209 4822 050 21002 4822 050 21003 3198 010 42310 1k 5% 0,1W 10k 5% 0,1W BC547BW

* From wk0218 onwards a new pt. 4 board is introduced to solve picture jerking & cracking noise problem by adding: 2286 4822 122 33761 22pF 50V NPO 0603
Note: The pt. 3 board is not published because it has minor track shifting to prevent short-circuit to MPEG shield casing. New pt 4 board layouts & circuits are enclosed. FRONT BOARD * From production wk0152 onwards a mask 3 version of the Front microprocessor IC7401 is introduced due to deletion of the Cue/Review features. The service code for the equivalent OTP versions read: 7401 9965 000 10681 OTP version 25 for FW-V220 7401 9965 000 10680 OTP version 25 for FW-V320 It is very important that these OTPs are used only on sets without Cue/Review feature! The mask ICs used in production can be recognized by their printing mark: - V220S53051 for FW-V220 and - V320S53061 for FW-V320 ETF BOARD * From production wk0139 onwards the following changes are made to improve current handling & reliability: 7612 7613 7614 4822 130 11201 4822 130 11201 4822 130 11201 PMBT2907 PMBT2907 PMBT2907
Note: 7209 base-emitter is shorted to function like a diode. * From wk0147 onwards a new Servo IC7212 (software version 6) is introduced to improve CD playability. The new IC is recognized by printing mark "MPEG01BS06" and is available under service code: 9352 701 41518 * From wk0152 onwards the Video CD Processor IC 7201 is replaced by ES3800FL. Because of this replacement the following changes are made to: - adapt supply voltage from 3,5V to 2,7V - adapt audio output level to 550mV 2250 2251 2266 2267 3258 3261 3262 3265 2020 552 94427 2020 552 94427 2020 552 94427 2020 552 94427 4822 051 30333 4822 051 30563 4822 051 30333 4822 051 30563 100pF 50V 100pF 50V 100pF 50V 100pF 50V 33k 5% 0,1W 56k 5% 0,1W 33k 5% 0,1W 56k 5% 0,1W
