I needed a service manual as the display on my oscilloscope was very dim. I thought I'd give owner-manuals.com a try, as they advertised a huge number of manuals. Sure enough they had one listed. I bought it hoping it would be useful... actually, I bought it hoping it would be readable! I've had manuals from online sources in the past, and been very disappointed. Not this time! An excellent manual, complete, and very readable. Using it I fixed my 'scope, and as such the manual was an investment that paid off manyfold. Do I have any complaints? One very minor one - The circuit diagrams could have been scanned at a higher resolution, as some of the details were a little difficult to make out - not impossible, just not as easy as my old eyes would like! Overall, I'm very satisfied with my manual, and I will certainly be using this company again. Well done.

I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, pages are very clear to read, some of the pages are a bit tilted but overall it is great to have this manual available for purchase. Thanks

1. CANCELING DETECTION BY THE TRAP SWITCH
� Canceling detection by the TRAP switch
For video data transmission from the HDMI input to the plasma display, digital signals are used. Therefore, this unit adopts the HDCP (High-bandwidth Digital Content Protection) system for copyright protection. This unit is also provided with a detection switch (TRAP switch) that will prohibit the unit from being turned on again if the rear case of the unit is opened, in order to prevent the panel technology from being leaked out. Function: To deactivate the detection of the TRAP switch Purposes: 1. During production of this unit, adjusting with the rear cover opened is possible. 2. During servicing or repairing, diagnoses of the assemblies are possible while the power is on. Methods: For setting, use RS232C commands: TSN: Ignore the monitoring of the switch CTM: Clear the detection log of the switch TSY: Reactivate monitoring of the switch Notes:
� � � � The TRAP switch is located on the chassis (see Fig.2 below). Once rear case opening is detected, send the TSN and CTM commands. Because the TSN command is not stored in memory, monitoring of the switch can be reactivated by turning the unit off then back on. The same setting is possible using the Factory menu.
