PHILIPS LED LCD TV - TYPE G SMPS - Circuit Diagram

Digital Main 1 Schematic Diagram –TYPE G SMPS.  Philips BA4AFSG02011 SMPS - LED DRIVER Schematic - Chassis FL14.10
   Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.  If Main Fuse (F602) 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.
For continued protection against risk of fire, replace only with same type 2.5A, 250V fuse.
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 when repairing.  Also, in order to have the ability to increase the input slowly, when troubleshooting this type of power supply circuit,  a variable isolation transformer is required.
