Troubleshooting
6-3-5 Horizontal Lines Spark or Image Ghost Appear On the Right/Left of Screen
6-8
1. Image Ghost appear
on the right/left of screen
2. When all R,G,B Channel has the problem,
change the value of PCLK on Driver in Service Mode.
3. When color difference by channel exists,
determine which channel fails after checking
the color of screen.
--> Magenta ->G Channel fails
--> Yellow -> B Channel fails
--> Cyan
-> R Channel fails
* Cause : The path between Pclock, Psync, CWData, CWEnable
signals that are input from Driver IC to Panel is distorted.
(Because the path on PCB depends on channel.)
* Countermeasure : Adjust the phase of Panel Clock
with using Serial Resistance (R309)
1. Horizontal Lines Spark Up/Down
