C6615LE 15” COLOR LCD TELEVISION Circuit
Diagram. Sylvania and Funai
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.
