 ;
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.
;
When I purchased this manual I had my doubts regarding the quality as the price was so reasonable as compared to other outlets.
The manual itself is of high standard the print is very clear as are the diagrams. Obviously with the diagrams one has to zoom in otherwise it is to small to be able to read.
Overall I am very pleased with the company who delivered as they said and with the manual they supplied.
I occasionally require a manual and now having registered with this company I shall order from them in the future.
;
I was at first dubious about payiong for downloaded manuals but having done so, I was extremely impressed with quality of the two manual I ordered, well worth the small price I paid.
I would highly recommend these to my friends.
;
reasonable price for the schematic - the service is perfect, all as expected and pointed by instructions - good scan of the original plans - thank you!

Flowchart for panel replacement
After replacing the panel with one for service, readjustment of the Vofs voltage margin is required.
[Preparations]
� Basically, the Panel Factory menu is used for the voltage margin adjustment. � The 60-Hz video sequence is used as the drive sequence. � While adjusting the voltage margin using the Panel Factory menu, the current drive sequence is indicated on the screen, as shown below. Make sure that "60VS" is always indicated during adjustment.

Example of the OSD while the Panel Factory menu is displayed
[Supplement]
� When the raster mask for margin adjustment is displayed during Panel Factory mode, the Panel White Balance is set to default, and the Panel Gamma is set to Straight in the "PANEL-1 ADJ" layer. On the third line, the OSD reads "- - - - /����" (���� stands for the type of the drive sequence set). � If you perform adjustment using RS-232C commands, use the commands shown below. These commands are different from those used during Factory Menu mode. PAV S00 : Used to set the Panel Drive mode to Factory. VFQ S03 : Used to set the Drive Sequence to Video 60 Hz. WBI S01 : Used to temporarily set the adjustment value of the Panel WB to default. (To return the value to its original value, use WBI S00.) PGM S00 : Used to set the gamma setting to Factory. Note: If the power is shut off in the process of the adjustment procedures, send the above commands again.
