GDS-1054B extremely dim screen

[Antonio90]

Hello everyone.
I just received my new GDS-1054B. Powered it on to see if it worked, fumbled around the menus and options a bit and did the probe compensation stuff with the 4 included probes. Then I powered it off and went to study for a few hours.
I then downloaded the latest firmware, put it in a usb key to upgrade and plugged it in before powering on the scope. It didn't boot into the interface while the usb light kept flashing for a few minutes, so I powered it off, took out the usb key and back on. The GW INSTEK logo appeared bright as before but then the backlight dimmed a lot and it has stayed like that.

The scope works, but the screen is extremely dim. I can see the waveforms well enough if the room is dark, but the "help" menu with it's grey background and black text is almost imposible to read no matter what, and I could read it just fine before.

I have upped the brightness in the "display menu", upgraded the firmware to 1.27, and downgraded to 1.12 to no avail.

Any ideas about what could be done?

Did you follow the safe update procedure? If not then try that first.

I updated it as specified in the instructions from GW INSTEK website: https://www.gwinstek.com/en-global/products/downloadSeriesDownNew/959/130
But it seems like the screen backlight might be dead, it doesn't light up anymore. The scope powers on, and lighting the screen very closely with my smartphone's flashlight reveals that it actually works (it kind of reflects the shapes that should be visible). However, it's completely black.
Oh well. I suppose shit happens 

Thanks for helping anyway
