POWER ON/OFF FUNCTION FOR THE LARGE-SIGNAL SYSTEM
50 DIGITAL ASSY
Short the two adjacent electrodes on the surface by a method
which assures continuity, such as using a crocodile clip.
Function:
It is an operational mode where the digital signal processing performs circuit operation but the power is not supplied to the panel
driving system (large signal system) in order to avoid a power down.
Application:
1. When it is necessary to check whether the signal output is correctly reaching the drive system in a repairing activity etc.
2. In the case of a PD, to determine whether the problem is with the large signal system power supply or with the small signal
system power supply.
Method:
1. Make shorting between the specified location (refer to the illustration below) of the PCB surface of the 50 DIGITAL ASSY and the
nearby pattern.
2. Execute [DRV S00] by RS232C command. ([DRV S01] for release)
Supplemental explanation:
• When the large signal system power supply is in OFF state, there will be no PD, except PS_PD, as the PD signal has been
muted.
• If the clip is removed in the OFF state of the large signal system power supply, PD will take place at the instance of clip removal.
Therefore, be sure to remove the clip after turning the power OFF.
• Under RS232C command control, [DRVS01] (release) is possible during power ON. However, there is a possibility of damaging
the set. Therefore, make this operation only after turning the power OFF.
• Command [DRVS00/S01] is effective even during standby. When the main power is turned OFF, however, [DRVS01] (release)
will be effective.
