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.

Great manual very clear copied. You are making an incredible job. I appreciate a lot the rapidity and your efficiency. Thanks a lot

s SOLDERING IRON
1. Use a high insulation soldering iron with a thin pointed end of it. 2. A 30W soldering iron is recommended for easily removing parts.
s REPLACEMENT STEPS 1. How to remove Chip parts
q Resistors, capacitors, etc. (1) As shown in the figure, while pushing the chip part with tweezers, alternately melt the solder at its each end.
2. How to install Chip parts
q Resistors, capacitors, etc. (1) Apply solder to the pattern as indicated in the figure.
(2) Grasp the chip part with tweezers and place it on the solder. Then heat and melt the solder at both ends of the chip part. (2) Shift the chip part with tweezers and remove it.
q Transistors, diodes, variable resistors, etc. (1) Apply extra solder to each lead.
