It was magic after so many years to still be able to source this info. It was equally amazing to return my Pioneer receiver to it near new sound quality AFTER NEARLY 30 YEARS! Thank you for this ability!
 ;
Very quick and easy website to use and fast download of manual, quality of manual is excellent and will be pleased to use this service again in the future, thanks so much!
 ;
Easy and secure way to get a complete service manual of a vintage hifi component. Only some parts of the print copy are dificult to read. Nice price!
 ;
The manual is an excellent reproduction with complete schematics, made troubleshooting and repair a simple process.
 ;
Up to now you are the BEST! Prompt-efficient and so reasonable ! I have been after SONY service manual for quite some time !Thank you very much ! I can recomend your service to
all my collegagues ! V.Bergfield .
(3) Measuring the Vs voltage Margin and deciding the voltage
¤ Convert the signal of signal generator to the 100% Full Red signal. ¤� Turn the voltage adjusting knob of Vs DC power supply to the voltage -down direction and make the cell of screen turned off. ¤� Turn the voltage adjusting knob of Vs DC power supply to the voltage -up direction until the cell of screen turned on. The first voltage, which make the cell of full screen turned on, is named as Vsmin1 and record it. ¤� Turn the voltage adjusting knob of Vs DC power supply to the voltage-up direction slowly until the cell of screen turned off or over electric discharge. The first voltage, which makes the cell of screen turned off or over electric discharge, is named as Vsmax1 and records it. (Only, Vs voltage variable passes over the maximum 190V) ¤º Convert the signal of signal generator to the 100% Full Green signal. ¤ Repeat the adjustment (2) item and name each voltage as Vsmin2/Vsmax2 and record them. ¤ Convert the signal of signal generator to 100% Full Blue signal. ¤ Repeat the adjustment (2) item and name each voltage as Vsmin3/Vsmax3 and record them. ¤ Convert the signal of signal generator to 100% Full White signal. ¤ Repeat the adjustment (2) item and name each voltage as Vsmin4/Vsmax4 and record them. ¤æ Convert the signal of signal generator to 100% Full Black signal. ¤ Repeat the adjustment (2) item and name each voltage as Vsmin5/Vsmax5 and record them. ¤ At this time decided Vs voltage adds 6V to Max value(Vsmin1~Vsmin5) and set up the voltage within the set-up range(180V < Vs # 190V) in consideration of other features. ¤ Turn the voltage adjusting knob of Vs DC power supply make deciding the Vs voltage. ¤ı Adjust Vset-down wave form using setting up Vs voltage like mentioned on the 4-3.
(4) Adjusting the final voltage wave form
Check the voltage wave form like the mentioned way on the 43(How to adjust) and readjust the wave form when it is twisted.
(5) DC-DC Pack Voltage Set up Range
Vsetup : 185V ~ 225V Vsc : 90V ~ 120V -Vy : -60V ~ -80V
