6-1. Signal Trouble Cases
We can classify the signal problem into three by checking whether Picture or Sound
is abnormal.
It is important to check whether both picture trouble and sound trouble occur,
because we can judge the cause is panel or video processor or sound processor.

2. The Idea of Diagnosis for LCD
Page 64
2-1. Diagnosis by Jig
<Purpose>
In case of LCD, the picture problem is mainly caused by LCD panel or DG(A) board defective.
This Jig is able to diagnose these defective parts.
<Model>
TC-32/26LX600 (for USA, Canada)
TC-32/26LX60 (for USA), TC-32/26LX60C (for Canada)
TC-23LX60 (for USA, Canada)
TC-32/26LE60 (derivartive model), TC-26/23LX60L (for Latin)
TC-26/23LX60C (for Mexico)
<How to connect the Jig>
(Original)
LCD panel
DG(A) Board
LVDS cable
T-con board
(on the panel)
<Jig>
Connecting Board
No : TZSC07063
Cable
No : TZSC09035
( Include Connecting board, Cable)
<Diagnosis>
If the test pattern is normally displayed,
defective parts is DG board mainly.
If the test pattern is abnormally displayed,
defective part is LCD panel side.

WB-ADJ is necessary when LCD panel is exchanged.
MTS-ADJ is necessary when tuner or Multi-sound-IC(IC2202) is exchanged.
Mainly, OPTION are not necessary to adjust and PCT_ADJ is done if necessary.

Basically, “OK” in green or “NG” in red is displayed.
But, NG of DT1, DT2, and HDMI are displayed
in hexadecimal number and NG of CEC is
displayed as ‘---’ .
SOS History
Note:
*1 DT1’s NG means the communication error
between VCTP and Peaks_Lite.
*2 DT2’s NG means the Peaks_Lite can’t communicate
with the peripheral devices such as EEPROM,
ATSC LSI (FRONT END LSI) and NTSC ENCORDER
through IIC bus line.

4: SOS History
We can confirm the record of Power SOS by Self-check.
This information is useful for service, if TV set sometimes shuts down
by power supply trouble.
Screen Display example LX600/LX60
SELF CHECK 03700-03700
UV OK DT1 OK DT2 OK
AVSWA OK FPGA OK HDMI OK
MEM OK VCTP OK CEC OK
SOS : 2 7
Note:
*This data is only displayed if TV set sometimes shuts down by power supply trouble
during the time from the former self check to the next self check.
*This data shows all kinds of LED blink that occurred during the time from the former self check
to the next self check.
*This data is cleared after self check.
In case of LED Blink 2 and 7 times
