Power Part.
  This part consists of the one 3.3V, and one 1.8V regulators to convert power which is provided 5V in Power board.  16V is provided for inverter, 16V is provided for LCD panel and 5V for micom.  Also, 5V is converted 3.3V and 1.8V by regulator. Converted power is provided for IC in the main board.  The inverter converts from DC16V to AC 700Vrms and operates back-light lamps of module.

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.  If Main Fuse (F601) is blown, check to see that all components in the power supply circuit are not defective before you connect the AC plug to the AC power supply.  Otherwise it may cause some components in the power supply circuit to fail.

The voltage for parts in hot circuit is measured using hot GND as a common terminal.

BECAUSE A HOT CHASSIS GROUND IS PRESENT IN THE POWER SUPPLY CIRCUIT, AN ISOLATION TRANSFORMER MUST BE USED.  ALSO, IN ORDER TO HAVE THE ABILITY TO INCREASE THE INPUT SLOWLY, WHEN TROUBLESHOOTING THIS TYPE POWER SUPPLY CIRCUIT, A VARIABLE ISOLATION TRANSFORMER IS REQUIRED.
