No Power
(Standby Power : I801)
The Standby LED doesn't light up red.
Approximately 150VDC is to C806.
The following waveform is to drain of I801.
100KHz
Check if voltages to PW15 is supplied to TV
micro-processor(I701).
When pressing Power button, the color of Power
LED is green
320Vp-p
END
NO
Check if F801 is open.
Check D801 (bridge rectifier).
Check the impedance value of between Source
NO
and Drain to I801. If the value is near zero Ω,
I801 is dead. Replace I801.
