Thanks for offering this item at such a good price. Proved handy in identifying the part I was looking for my set.
Thanks again.
;
This is the original manufacturers service manual, with detailed info on the circit boards, explosion drawings of all parts in assembly order, and tuning instructions. The only thing missing is the information on the dimensions of the various drive belts. mail me if you need them. gcrossman_at_aol.com

Ordered service manuel for a hard to find plasma tv - your company made it easy to find and purchase - I will use you again
Thanks for your help
 ;
This is a high quality manual with clear schematic and components layout diagrams ; with service procedure included.

This service manual for the Kenwood KT-990D was reproduced really well ,is very legible and manual is complete.Combined with the low price paid,in the future,I will be checking Owner-Manuals.com any time I need a manual.
DV-535
WARNING! THE AEL(ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.
LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 655 nm FOR CD : MAXIMUM OUTPUT POWER : 5mW WAVELENGTH : 785 nm
LABEL CHECK
WYXJ, WYXJ/SP, WVXJ and WYXQ types
(Printed on the Rear Panel)
Additional Laser Caution 1. Inside detection switch (S201 on the SMEB assy) and loadingstatus detection switch (S101 on the LOAB assy) are detected by the microprocessor (IC11 in the DVDM assy). � To permit the laser diode to oscillate, it is required to set the inside detection switch for the inside position (S201 : ON) and to set the loading-status detection switch for the clamp position (the center terminal of S101 is shorted to +5V). The 650 nm laser diode for DVD oscillation will continue if pin 19 of IC1 is shorted to +5V (fault condition) in the DVDM assy. The 780 nm laser diode for CD oscillates if pin 20 of IC1 is shorted to +5V in the DVDM assy. In the test mode � , the laser diode oscillates when microprocessor detects a PLAY signal, or when the PLAY key is pressed (S706 ON in the KEYB assy), with the above requirements satisfied. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam. � : See page 49.
