19.IC7002 (RH-iXC331WJQZQ)

This is a monitor microprocessor, which receives the remote control light, controls the CEC signal, detects the keys, and detects the OPC. It also
detects the errors relating to the power supply within the IF PWB and controls the power supply of the monitor.

20.IC7006 (VHiBR24L04F-1Y)

This is an EEPROM, in which the portion of the data processed by IC7002 is stored.

21.IC5802 (VHiLTC1154+-1Y)

This is a power supply IC, which supplies 5V for the optional wireless transmission unit. It also detects short circuits and has the thermal shutdown
function.

22.IC5901 (VHiBD9045FV-1Y)

This is a DC/DC converter, which inputs 15V from the power supply unit and generates 5V and 3.3V used within the IF PWB.

 2ch DC/DC Converter

MODE2

I

Distribution, DDR function enable.
The use of these multi-function depends on the setting of MODE<1:0>.
  MODE<1:0>=HH(Single-in/Single-out Mode)
     H: Distribution function enable.
     L: Distribution function disable.
  MODE<1:0>=HL(Single-in/Single-out Mode)
     H: DDR (Double Edge input) function enable.
     L: DDR (Double Edge input) function disable.
