May 31 13:11:09 (none) main: 63.86 VIDEOLC-0 I: VLC_DisplayBacklightControl: backlight on

May 31 13:11:09 (none) main: 63.86 VIDEOLC-0 I: VIDEOLC_doReadyPowerManagementCnf done, no error

How can i test the exact status of dislay.

Logs are attached.

Hello,

it could be that the inverter board is broken. We have a ddts open for this.

CSCuc95415 - Hardware : EX-Series LCD screen remains black all the time

If the inverter board has gone bad, you still should see some faint image if/when you light up the screen with a torch light or your smartphone's flash. See the sample clip included below.

If you can confirm this is what you "see" then an RMA will need to be done.
