and is the signal output?
The pattern and circuit from the HDMI
connector (JK151) to the IC151 are defective,
or HDMI output circuitry is defective (IC151
and surrounding circuitry).
YES
The pattern and circuit from the HDMI
connector (JK151/152) to the IC151 is
defective, or HDMI output circuitry is defective
(IC151 and surrounding circuitry).

NO
vicinity of JK152?
With the TV connected,check the voltage of the IC on
the side on which the TV is connected. Is communication
waveform confirmed in TP[DDC_CLK/DDC_DATA] in the

(Zone2:ON, Source Select:Source)
(34) Is the "H"(3V-5V) signal outputted of TP[HPD] in the
vicinity of JK507?
With the TV connected,check the voltage of the IC on
the side on which the TV is connected. Is communication
waveform confirmed in TP[DDC_CLK/DDC_DATA] in the
HDMI connector (JK507)?
Is D5004-D5011 terminated by the TMDS signal of 3.3V
and is the signal output?
For failure of Monitor out1/2, the pattern and circuit from the
HDMI connector (JK151/152) to the IC151 is defective, or HDMI
output circuitry is defective (IC151 and surrounding circuitry)
For failure of HDMI ZONE2, the pattern and circuit from the
HDMI connector (JK507) to the IC501 is defective, or HDMI
output circuitry is defective (IC151 and surrounding circuitry)
perform the troubleshooting again from (21)
