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!

This is a very good quality print (scan) of the original SONY service manual. The original from Sony is on very thin paper. Nevertheless it is very clear and sharp and excellent readable. I'm very satisfied to have now this rare document. I've looking for it many years (infrequent). It contains very detailed circuit diagrams, exploded views, part lists, PCB view with good readable connection lines. Very recommended.
;
A complete manual with all the needed details of calibrations and service instructions about the radio receiver.
A big deal.
Many thanks !
SM00025 Service Manual
Next enter the digital audio setup menu and change the decode mode from �Auto� to �Analogue�, to �Digital� and then back to Auto. Make sure no �pop� or �crack� noises are heard on the speakers. Access the speaker setup menu via the remote control and turn off all the amplifiers. Check pins 1,2, and 3 of PS08 of the decoder board go low. Any speakers connected should now be muted. DOLBY DIGITAL TESTS **Set the master volume control to maximum. Check that an undistorted continuous* sine wave can be seen at the following level on the channels below at the phono socket E401. *The Audio will obviously show a transient as the track repeats. There should not be a glitch otherwise. Signal L R C LS RS Level 2Vrms / 5.6Vpp @30Hz 2Vrms / 5.6Vpp @30Hz 2Vrms / 5.6Vpp @30Hz 2Vrms / 5.6Vpp @30Hz 2Vrms / 5.6Vpp @30Hz
Signal L R C LS RS
Level 30Hz signal between 2Vrms and 2.1Vrms 30Hz signal between 2Vrms and 2.1Vrms 30Hz signal between 2Vrms and 2.1Vrms 30Hz signal between 2Vrms and 2.1Vrms 30Hz signal between 2Vrms and 2.1Vrms
***The Audio will obviously show a glitch as the track repeats. It should not glitch otherwise. At this point, it is normal that the woofer channel will show clipping. Turn the main volume down and check that you can achieve at least 3Vrms / 8.5Vpp without clipping. Remove the input to E408 and apply the optical input from the DVD player to I407 and repeat the test from ****). MPEG Using an MPEG Multi-channel encoded disc, (such as the film �Jumanji�) apply the digital coaxial or optical output from the player to the amplifier board. Check the OSD displays MPEG Multi-ch. Check audio can be seen at all channels on E401. ANALOGUE / PRO LOGIC MODE Remove the digital source either from I407 or E408. Make sure the volume control is at Maximum. Using a Pro logic encoder, apply a 2V 1KHz Lt Rt signal to the Audio inputs of the selected AV. Using a pro logic encoder, generate signals for each channel in turn (L, R, C and Surround) and make sure they appear undistorted at the correct outputs on E401. At the following levels:Signal L R C Level
1KHz signal between 2Vrms and 2.1Vrms
At this point, it is normal that the woofer channel will show clipping. Turn the main volume down and check that you can achieve at least 3Vrms / 8.5 Vpp without clipping. Remove the input to E408 and apply the optical input from the DVD player to I407. Check the symbol Dolby D 3/2.1 appears (Press recall/info if it doesn�t) Repeat the test from **). DTS Select track 15 on the DTS test DVD. Set the player for �repeat play�. Apply the coaxial output of the player to E408 on the audio amplifier board. ****Set the master volume control to maximum.
LS Check the OSD indicates DTS 3/2.1. If it doesn�t appear, press the recall/info button on the handset. Check for an undistorted continuous*** sine wave can be seen at the following level on all channels at the phono socket E401. 31 RS
1KHz signal between 2Vrms and 2.1Vrms 1KHz signal between 2Vrms and 2.1Vrms 1KHz signal between 1.41Vrms and 1.5Vrms 1KHz signal between 1.4Vrms and 1.5Vrms
Put the master volume to mid way and un-mute the amplifiers via the speaker setup menu.
