When using a Marantz
BD/DVD player, is the FL
display's "HDMI" indicator lit?
If using a non-Marantz BD/
DVD player, proceed to "NO".
YES
(20) VIDEO CONVERT : Is the picture output when it is set to off?
(After item (23) : To be "VIDEO CONVERT:OFF" setting.)
The HDMI input circuitry is defective.
(IC111 or IC121 and surrounding circuitry)
Check operation of each device.
(AMP source : BD[i/p:Analog&HDMI,MONITOR OUT:Auto] / Video
input of player : 480P / Connect the TV.)
Check operation of IC111(ADV3002).
(21) Check power supply.
Are 5V or 3.3V supplied to IC111 (each power supply pin)?
Refer to [Detail C] of the substrate for test point.
(22) Check RESET.
Is RESET waveform confirmed in TP[3002_RESET], when power
is turned on?(If the waveform is not the reference waveform,
proceed to NO.)
(23) Check Control signal (I2C).
Is waveform confirmed in TP[HDMI_SCL/HDMI_SDA], when
power is turned on? (If the waveform is not the reference
waveform, proceed to NO.)
(24) Check output signal.
Is TMDS waveform confirmed in 25pin/26pin/28pin/29pin/31pin/3
2pin/34pin/35pin.
Is communication waveform of DDC_SCL/DDC_SDA confirmed
in 67pin/68pin? (If the waveform is not the reference waveform,
proceed to NO.)
The BD/DVD player does not recognize the
connection with the set.
(19)
Is the "H"(3V-5V) signal outputted of HDMI
connector (JK101/JK111/JK112/JK113/JK114/
JK121/JK122 : TP[HPD])?
With the BD/DVD player connected, Check
voltage of the HDMI connector for the input on the
NO
side on which the BD/DVD player is connected.
Is communication waveform confirmed in
TP[DDC_CLK]/TP[DDC_DATA] around each
HDMI connector ?
Is TMDS line of HDMI connector terminated by
the TMDS signal of 3.3V and is the signal output?
YES
