LVDS
Video Signals from the Main Board to the Control Board are referred to as Low
Voltage Differential Signals or LVDS. Their presence can be confirmed with the
Oscilloscope by monitoring the LVDS signals with no input signal selected while
pressing the Menu Button "on" and "off" with the Remote Control or Keypad.
Loss of these Signals would confirm the failure is on the Main Board!
