 DP-86DA MITSUBISHI Service Manual by Sam Kapasi;
This manual is for the usa model only. But it is clear , accurate and comprehensive, including board layouts and schematics. I found it extremely useful for my mitsubishi dp-86da, but the same diagram would also work for the realistic lab5000 and hi fi 80. Thanks.

Great to have extra resources for Service Manuals, Now days you can really not trouble shoot efficiently without one , Wayne at IRIONS TV & ELECTRONICS REPAIR Clearwater , Fl. 33755 727-446-7955
 A-103 TEAC Service Manual by Mike Dunn;
For five bucks you can barely buy a hamburger. Or for the same five bucks you can buy a service manual. Much more useful. (and better for your health, depending on where you buy your hamburgers). Yes, there are free manual sites out there, but if they don't have what you want, you have to pay. And five bucks isn't much. Not for full specs, schematics and adjustment and parts replacement procedures. My only criticism is that grayscale illustrations aren't well rendered, but I've seen worse. Schematics and text are clear. I'll be happy to purchase from here again. Mike [email protected]
 CJV55 PIONEER Service Manual by Joseph Dulick Jr;
Impressively thorough. Even the simple operators manual helped me "fix" one of the 2 CD players in the unit. This unit reads CD's from the top so they should be installed in the magazines "upside down" from typical CD players. The CD player service manual helped me unjam a stuck carriage because somebody transported the box laying down loaded with CD's. A little lens cleaning & the player now works well! Thanks for you help at a great price! Joe
 PMD-221 MARANTZ Service Manual by Benjamin AM;
I was skeptical at first but later found the manual to be good quality for the price. It took a couple hours to receive the email with the download link, well worth the wait. Thanks.

5) Focus and Tracking Automatic Gain Control
This function is used for implementing automatic control of the focus and tracking loop gain. The following is the adjustment procedure : (1) Inject disturbance to the servo loop. (2) Extract the error signal (FE and TE) generated at when the disturbance is applied to obtain the signals G1 and G2 via the B.P.F. (3) The microcomputer reads the G1 and G2 signals via the LSI. (4) Based on the necessary correction calculated by the microcomputer, the LSI performs the loop gain adjustment. Above adjustments are repeated several times to ensure higher adjustment accuracy.

This adjustment takes place at the following timing : ⢠When the focus close alone is completed during the setup process. ⢠Just before the setup is completed (just before the play takes place). ⢠After the off-focus has been corrected during the play.

7) Adjustment of Pre-Amp Stage Gain
It is used for adjusting the entire RFAMP (FE, TE and RF amplifiers) to +6dB or +12dB depending on given gain level when reflected light from the disc is significantly below the required level due to stained lens. This phenomena can be noticed when playing back the CDRW. The following is the adjustment procedure : When reflected light from disc is judged to be significantly below the required level during the setup, set the entire RFAMP to +6dB or +12dB. In this case, if the gain is modified, the setup have to be repeated from the first step. Through the adjustment, if you judged the play becomes available by setting the entire RFAMP to +6dB, +6dB should be selected for the setup next time on. See the figure below :

6) Automatic RF Level Adjustment (RFAGC)
This adjustment is used for implementing intended signal transmission successfully by adjusting unevenness of the RF signal (RFO) levels, that results from disc and machine relevant factors, to a target value. The adjustment is actually done by varying gain of the amplifier provided between the RFI and RFO. The following is the adjustment procedure : (1) Using the command, the microcomputer reads the output from the RF level detection circuit on the servo LSI. (2) Based on the read value, the microcomputer calculates an amplifier gain that will produce the target RFO level. (3) The microcomputer sends the corresponding command to the servo LSI so that the above gain value may be set.
