TROUBLESHOOTING

13.Troubleshooting 

 

A. No Backlight Problem   

 

Problem: 

If TV is working, led is normal and there is no picture and backlight on the panel.   

Possible causes: 

Backlight pin, dimming pin, backlight supply, stby on/off pin 

BACKLIGHT_ON/OFF pin should be high when the backlight is ON. R119 must be low when the 
backlight is OFF. If it is a problem, please check Q10 and the panel cables. Also it can be tested in 
TP50 in main board.   

 

 

 

 

 

Dimming pin should be high or square wave in open position. If it is low, please check S60 for Mstar 
side and panel or power cables, connectors.   

Backlight power supply should be in panel specs. Please check Q33, shown below; also it can be 
checked TP53.
