7.1.3 DIAGNOSIS WITH THE AID OF FACTORY MODE

• Diagnosis with the aid of Factory mode
When the Media Receiver is connected, the power-down and shutdown logs can be referred to with OSD. Only the items
useful when servicing the PDP-435PE/PRO-435PU are described here.
How to enter Factory mode using the remote control unit
Please refer to the technical documentation. (Service knowhow is the same as G4 PDP models.)
Power-down log (INFORMATION-PANEL PD)
The last 8 power-down records are held, with the latest power-down displayed at the top. In the FIRST column, the location
where the PD circuit was activated first (location indicated by flashing of the LED during power-down) is indicated, and in the
SECOND column, the location where the PD circuit was activated second is indicated.
Note: There may not be a SECOND PD.
