Dark screen | Check circuits related to the "backlight": backlight = a lighting system using thin fluorescent lamps mounted on the back of the display and activated by one or more panels (inverter panel), this panel is supplied with low voltage from the power supply ( 12 or 24v) and raises this voltage to approximately 900v. Activation of the "backlight" panel comes from the ssb panel through the lamp_on command. - for models with tcon control panel: check power supply to the tcon panel, on the lvds cable that connects the ssb panel to the tcon panel, check the signals from the ssb/tcon panels (signal similar to a video pedestal) with an oscilloscope, when possible /necessary to clean the lvds cable terminals. | Silva | |
