I received my Pinetab 2 (ARM version) in early June and the screen worked fine. The screen would go off due to power saving but tapping the screen or keys would bring the screen on again after a bit. However, I was using the Pinetab 2 with the screen working, I left for a few minutes and on return the screen was off. When I tried tapping the screen or keys then the screen didn't come on. Now the screen is always blank/black whatever I try. I've tried the brightness key (Fn+F2) many times, tried rebooting, powering off and then back on again, tried tapping the screen and keys. The keyboard backlight, not the LCD backlight, still works so the keyboard must still be being powered and does work, see later. I've attached the serial dongle and the Pinetab 2 does boot up and systemctl shows the displayer manager, sddm.service - Simple Desktop Display Manager, active. If I type the password on the keyboard and press enter, although there is still nothing on the built-in display, I can see that the user has logged in on the serial console!
Further, I've attached an external monitor via the HDMI port and it displays on external monitor fine. When I played with removing and then adding back the built-in screen the GUI had lock-ups for a few seconds at a time.
There are error message in `dmesg`:

The touchscreen works because I can do gestures on the screen and they effect the desktop as seen via HDMI.
I've installed the latest updates which included an initramfs rebuild but made no difference.
I've reinstalled the kernel but this has made no difference.

I'm pretty sure this is a hardware fault. I've reported the issue to Pine64 support and they have recommended coming here for further diagnosis and will RMA if it is a hardware fault so I appreciate any help on diagnosing this issue.

It's likely a faulty display unit. To be sure please try to reflash the factory image. If the issue persists then it is relatively safe it was not a bad flash at the factory. For details see https://wiki.pine64.org/wiki/PineTab2#Software.

I downloaded the factory reset image from https://echo.danctnix.org:7269/danctnix-...527.img.xz, wrote it to a microSD card and verified that the image written to the microSD matched the uncompressed downloaded image. I then booted from this image using the serial dongle starting with "SD BOOT" to ON and switching it to OFF once the kernel started booting (also tried it lots of other ways!). The output on the serial console shows a different Linux version being booted, still has the drm crash, shows the eMMC being detected, there's an error about "GPT:Alternate GPT header not at the end of the disk." but I guess that's normal due to the nature of the image, then the log messages stop at "Starting network: OK", a bit later get "[ 86.239708] random: crng init done" and then nothing else happens. I'm not sure what is meant to happen but I'd expect some messages on the console about it flashing the factory image. Perhaps it is meant to display something on the built-in screen? I left it for over an hour but when I ejected the microSD, rebooted and it booted into the same unchanged system I'd left on the eMMC; it had not installed a factory version of the image. I'm guessing that the broken built-in screen is breaking the factory reset install process or maybe options appear on the screen and you have to choose to do the factory install?
Unless that drm crash is normal on boot up then I'd say this proves the screen is broken because it was a different Linux version, nearly certainly the factory image reset installer one. Let me know if it isn't enough proof and what else I could try.

That's fine and I don't think there are any further tests, you can confirm the support that it's a faulty screen.
Hello,
I too have the same blank screen issue.
When I first turned on the PineTab2 the screen didn't come on.
I tried many different combinations of power cycles.
Eventually (after a few days) I had left it unattended in a state I thought was off, but noticed the screen didn't appear completely black.
It turned out the PineTab2 was on and I was able to login and use the screen.
However I then turned off the PineTab2 and have not been able to get the screen to work again since.
I have yet to connect via the dongle or the external HDMI. The keyboard backlight responds appropriately, and I have also tried all the screen adjustment options on the keyboard, with no success.
I will investigate further and post again.
I have tested my PineTab2 further and have found similar behavior as described in the initial post.
I have submitted a ticket with the Pine64 store and they also directed me to "community channels" for further diagnosis and help, so I will continue positing here.
Currently the PineTab2 display does not come on at all.
I can connect with the external HDMI and see the output on an external monitor as expected.
I connected with the dongle and can log in to a serial terminal as expected.
I reflashed with the factory image from https://echo.danctnix.org:7269/danctnix-...527.img.xz however the screen still does not come on.
The following are error messages in the dmesg output before the reflash.

[ 1.603449] rockchip-drm display-subsystem: [drm] fb0: rockchipdrmfb frame buffer device
Before and after the reflash the version info at the start of dmesg was the same.
Code: [ 0.000000] Linux version 6.3.0-2-danctnix (builduser@alarm) (aarch64-unknown-linux-gnu-gcc (GCC) 12.1.0, GNU ld (GNU Binutils) 2.38) #1 SMP PREEMPT_DYNAMIC Fri May 26 07:05:36 UTC 2023
In the dmesg output there is the message " Failed to create device link (0x180) with vcc_3v3" just before the errors, occur.
Can anyone with a working screen check if this message is in their dmesg output?
Not sure what else to log. Hope someone has some extra insight.

Hi,
I don't have any information, but I am also experiencing this (black screen, even when trying to boot from factory image, keyboard backlights are only sign of life).
I'll try to get my hands on a usb data cable and/or a hdmi -> micro hdmi cable and see what I can find.
Following the directions from the wiki page to connect to the UART adapter, I run into trouble as I don't see a /dev/ttyUSB0 on my system.
But that's mostly fine, as I was able to connect to an external display with the HDMI.
I flashed the factory image (no trouble booting from the SD card) and powered it off.
Restarting and disconnecting the external display... there is still nothing on the Pinetab's screen.
Ah well. At least I can see some things now, I can look for logs.
I have exactly the same issue (blank screen, error in drm_mode_object_add):/ the UART log is at https://pastebin.com/4rv7gbYE .
Quote:Following the directions from the wiki page to connect to the UART adapter, I run into trouble as I don't see a /dev/ttyUSB0 on my system.
I first plugged the cable into the other USB port, it has to be in the one labeled DEBUG. Perhaps run "dmesg -w" and you should see something like this after you plug it in (it does not have to be in the PineTab, as it takes power from your computer):

Thanks!
Watching dmesg -w on my desktop when I plug in the adapter, I see messages like that, but then immediately afterwards it gets detached from ttyUSB0.
Only once out of the ~5 times I tried plugging it in did it remain attached to ttyUSB0. Odd. But it seems to work better with other devices.

And yeah, I also found warnings in dmesg around drm_mode_object_add.
