OK?..manual is complet and helpfull... for repairing such a old and rare boombox like JVC PCM it is necessary...
;
Super Anleitung. Ordentliche Auflösung. Das ganze noch in Deutsch wäre zu schön. Alle Datenblätter sind sauber Kopiert und alle Leitungswege sind sauber ausgeführt

Thanks God for the internet and thanks for the service like this - proffessional solution on time.

About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

The downloaded quality was as good as the orignial
3.JITTER CHECK 1) While oscilloscope is kept connected in the same test point as in step2. RF WAVEFORM CHECK, connect the output terminal of an oscilloscope to the input terminal of the jitter meter. 2) 3) 4) Set the VOLT range selector of oscilloscope to 500mV range or below. Play back 2nd track of TCD-782.

Check that jitter meter indicates 28.0ns or less.

4. PLAY ABILITY CHECK 1) Play back the 3rd , 8th and 13th track of ATD-001. Check that the noise does not occur sound skipping does not occur.
5.LASER CURRENT CHECK *Do not perform this measurement unless the laser is suspected to be defective. 1) 2) 3) Connect digital multi-meter across the resistor R402(10Ω). Play back the TCD-782 and check the DC voltage value on the digital multi-meter. Calculate the laser current (Iop) by dividing the DC voltage across R402 by the resistor value (R402= 10Ω). Check that the laser current (Iop) is 60mA or less.
