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

DSC-V1 SECTION 1 SERVICE NOTE
COVER
1-1. NOTE FOR REPAIR
Make sure that the flat cable and flexible board are not cracked of bent at the terminal. Do not insert the cable insufficiently nor crookedly.
When remove a connector, don�t pull at wire of connector. It is possible that a wire is snapped.
When installing a connector, don�t press down at wire of connector. It is possible that a wire is snapped.
Cut and remove the part of gilt which comes off at the point. (Be careful or some pieces of gilt may be left inside)
1-2. DISCHARGING OF THE ST-083 FLEXIBLE BOARD�S CHARGING CAPACITOR (C333)
The charging capacitor (C333) of the ST-083 flexible board is charged up to the maximum 300 V potential. There is a danger of electric shock by this high voltage when the capacitor is handled by hand. The electric shock is caused by the charged voltage which is kept without discharging when the main power of the unit is simply turned off. Therefore, the remaining voltage must be discharged as described below. Preparing the Short Jig To preparing the short jig, a small clip is attached to each end of a resistor of 1 k� /1 W (1-215-869-11). Wrap insulating tape fully around the leads of the resistor to prevent electrical shock.
1 k�/1 W
Discharging the Capacitor Short-circuit between the LND390 (positive) and the LND391 (negative) terminals on the ST-083 flexible board with the short jig about 10 seconds.
