SYLVANIA C6615LE 15 inch COLOR LCD TELEVISION Circuit Diagram

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.
