Check operation of each device.
(AMP source : CBL/SAT/Video input of player : 480P / Connect the TV.)
Check operation of U1001(ADV3002).
(22) Check power supply.
Are 5V or 3.3V supplied to U1001 (each power supply pin)?
Refer to [Detail C] of the substrate for test point.
(23) Check RESET.
Is RESET waveform confirmed in TP[3002RESET], when the power is turned
on?(If the waveform is not the reference waveform, proceed to NO.)
(25) Check output signal.
Is TMDS waveform confirmed in 25pin/26pin/28pin/29pin/31pin/32pin/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.)
(24) Check Control signal (I2C).
Is waveform confirmed in TP[HSCL/HSDA], when the power is turned on? (If
the waveform is not the reference waveform, proceed to NO.)
The power supply circuitry is defective.
The RESET circuitry or U1001 is defective.
The U1001 is defective.
The pattern is defective of the HSCL/HSDA
line.
NO
NO
NO
NO
The HDMI input circuitry is defective.
(U1001 or U1302 and surrounding circuitry)
Check operation of U1302 (ADV7850).
(26) Check power supply.

NO
(21)
VIDEO CONVERSION : Is the picture output when it is set to off?
(After item (22) : To be "VIDEO CONVERSION:OFF" setting.)
YES
U1601(ADV8003) and surrounding circuitry
are defective.
YES
YES
(19)
When using a
DENON BD/DVD
player, is the FL
display's "HDMI"
indicator lit?
If using a non-
DENON BD/DVD
player, proceed
to "NO".
The BD/DVD player does not recognize the connection with the
set.
(20)
Is HDMI connector (N1001/N1002/N1003/N1004/N1302 : TP[HPD-IN1
- 5]) set to "H"(3V-5V)?
With the BD/DVD player connected, Check voltage of the HDMI
connector (N1001/N1002/N1003/N1004/N1302 : TP[ +5V - IN 1 - 5 ]) for
the input on the side on which the BD/DVD player is connected.
Is communication waveform confirmed in TP[DDCCLK / DDCDATA IN
1 - 5] around each HDMI connector ?
Is TMDS line of HDMI connector ( N1001/N1002/N1003/N1004/N1302 )
terminated by the TMDS signal of 3.3V and is the signal output?
The pattern and
circuit from the
HDMI connector
(N1001/N1002/
N1003/N1004/
N1302) to the IC
(U1001 or U1302)
are defective.
NO NO
