Excellent service manual, the only known point of note is the alignment of improvability scanned pages within the pdf page. The resolution is good.

I was very glad recieving the service manal from You. Additionaly very fast. Extremaly nice servicing. Thanks very mach! Now my GX-220 working better, than it was made. Alexander from Moscow, Russia/

Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!

It was just what I need to fix my old BMW's CD player. Very convenient also. Thank you.

Great Manual! It contains all the wiring schematics and mechanical exploded views that are essential for service and repair. I was surprised I even found this for such an old machine. Only wish I knew of this site many years ago.
CD SECTION
Note: 1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10M impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. 5. Adjust the focus bias adjustment when optical block is replaced. Focus Bias Adjustment

S Curve Check
oscilloscope CD board TP (FEO) TP (VC)
Procedure : 1. Load CDs into the each tray (seven pieces). 2. Connect oscilloscope to test point TP (FEO). 3. Connect between test point TP (FOK) and Ground by lead wire. 4. The focus search is performed by turning ON the SYSTEM POWER. It searches DISC 1-7 in order and stops. 5. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 2.4 ± 0.7 Vp-p.
S-curve waveform symmetry
Procedure: 1. Connect oscilloscope to test point TP (RF). on CD board. 2. Turned SYSTEM POWER switch on. 3. Put disc (YEDS-18) in to playback the number two track. 4. Adjust RV101 so that the waveform is clear. (Clear RF signal waveform means that the shape � � can be clearly distinguished at the center of the waveform.) 5. After adjustment, check the RF signal level.

6. After check, remove the lead wire connected in step 3. Note: � Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. � Take sweep time as long as possible and light up the brightness to obtain best waveform. RF Level Check

Procedure : 1. Connect oscilloscope to test point TP (RF) on BD board. 2. Turned SYSTEM POWER switch on. 3. Put disc (YEDS-18) in to playback the number two track. 4. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not. Note: Clear RF signal waveform means that the shape � � can be clearly distinguished at the center of the waveform.
