 Replying to [comment:2 jg]:
 >We had gotten the trac. #660 backlight issue machine today,
 that it appear high-frequency noise and no backlight when power on .
 After measure the backlight led driving circuit that found led power not
 be turn on. the caused is Q2 ( MOSFET )Opened that
 replace new one and power on again it's work fine and the noise disappear.
