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.
