noise random green pixel when plugged power supply only (solved. see edit.)

[BatteryDie]

Hello world. Hello world.

I received my pinebook 14 inch yesterday. It came with 3 half-dead black pixel on white background on original Xeinial Mate image ship. It is really not big deal. I just ran script to upgrade kernel, u-boot, and system to get rid of flicker backlight brightness problem. I started noticed noise random green pixel when I plugged power. Blue, green, and gray background are affected. Unplugged power will stop noise random green pixel in Armbian 5.32 image but Xeinial Mate 0.6.2 will not… just slowly continue in battery mode until sleep and wake up.

I am not only one. There is other person who have same problem as mine but he don’t mention power supply plug-in. Here’s link https://forum.pine64.org/showthread.php?tid=4843 That video is exently same problem as mine.

Sadly, Armbian 5.32 image caused my laptop got permanent 4th dead green pixel. It is worse nightmare than half-dead black pixel. I decided stop using Armbian image to come back Xeinial Mate 0.6.2. here's image https://drive.google.com/open?id=0B9ywmn...mR4bzhoUlE My eyes see green

Here’s spec of my power supply https://drive.google.com/open?id=0B9ywmn...TZEdjVKQXc Some guy in IRC said it’s ok.

Here are images I used
1. Original Xeinial Mate. (I am sure it is 0.5.2.)w
2. Upgraded Xeinial Mate 0.6.2 or 0.7.10-105, I think. I lost tracking again.
3. Stretch Minimal 0.7.10-105
4. Armbian 5.32

Now, I am using Xeinial Mate 0.6.2 on eMMc. (linux pinebook 3.10.105-bsp-1.2-ayufan-77 #1 SMP PREEMPT Sun July 7 12:09: UTC 2017 arcg64 GNU/Linux) I am trying redownload Xeinial Mate 0.5.2-59 for SD card now. I’ll update it later.

P.S. I opened ticket support for just in case. maybe they send replacements board (and screen if they can) if USB adapter as power supply still caused problem.

EDIT: Downgraded Xeinial Mate 0.5.2. There are no longer noise random green pixel when i plugged power supply but backlight brightness flickering made me triggered mad until turn off auto reduce backlight brightness on power management for battery mode or upgrade 0.6.2. i have no choice. Just disabled auto reduce backlight brightness. I played wallpaper background with blue. No problem at all. Thanks to guy at IRC for tips. I thinking get screen replacement due to permanent 4th dead green pixel. Im updating ticket support.

Also, I really like Armbian because chrome performance and good modified XFCE and preinstalled programs. but I must stay away from Armbian 5.32 or upgrade Xeinial Mate 0.6.2 to avoid noise random green pixel problem. Keep in Armbian 5.32 and Xeinial Mate 0.5.2 still uses 56hz refresh rate. Xeinial Mate 0.6.2 uses 63hz. I think it is power management software problem, not refresh rate. Right now, I wanted report bug software but where? Let me know thanks.
