Does the power display on
the front panel change to
lighting in green after ap-
proximately 10 seconds?
Check the voltage of pins
1,3-7 of N1019 on the HDMI
PCB while the power display
is ashing in green or white.
Remove the connector (CP4001) of the SPK PCB.

secondary side, and check
the circuit for short circuits.
Replace any faulty parts.
Replace the fuse after repair.
Check for short circuits between
the regulator output terminal and
