Great tape deck manual!
I'm very positively surprised, because it is a very long manual, lot of pages, drawings, diagrams, description of how to make the alignment and adjustment procedures.
It is as good as the old "Naka" manuals from the 1970's - if somebody have seen them, they know what I mean by that.
I recommend to buy this very much !

If the switch is set to internal signals, it will operate without external signals, but the screen will be displayed in full white. Therefore the module operation can be checked without the A/V board. Here, be aware that the pin 8 and pin 9 of the power B /D� s CN802(11p), which is located above the module� s logic B /D, must be shorted and the A/C power supplied in order for the module to oper ate normally. Pin 8 is marked as PS-ON below the connector (CN802). If module itself is tested and it does not power on or the picture is abnormal, the module is defective. When reconnecting the A/V B /D, make sure to change the switch to external signals. - The most common module defect i s the appearance of a black or bright vertical line.
