The Mirror Time and IOP measurement allows you to make
diagnosis and adjustment simply by using the remote commander
and monitor TV. The instructions, diagnosis results, etc. are given
on the on screen display (OSD).

The Mirror Time and IOP measurement is required is such events
where servicing a DVD-Player includes changing the Base Unit
(BU). For each new BU to be used with a certain DMB10 board,
Mirror Time and IOP measurement need to be carried out.

Press three buttons  

x  

,  A and  VOLUME  + simultaneously

with the DVD player in standby mode.
The Test Mode starts, then the menu shown below will be
displayed on the TV screen.

MODE)

1. Connect an oscilloscope to CN105 pin 6  (RFMON) and

CN105 pin 3 (GND) on the DMB10 board.

2. Turn the power on.
3. Set the test disc (DVD: HLX-503 (NTSC) or HLX-504 (PAL),

CD: YEDS-18) on the tray and press  H  button to playback.

4. Confirm that oscilloscope waveform is clear and check

RFMON signal level is correct or not.

A clear RFMON signal waveform means that the shape “

◊” can be

clearly distinguished at the center of the waveform.
