The best thing for you to do would be to post this in the thread of the Android Build that you are trying to run. and not into the main Android Development thread =-].
Panel setting
You need to change the panel setting (1,2 or 3) in you default.txt or if you are using the nand method, try a differnt nbh.

My tablet is displaying horizontal bands of colour, the same colours as what should be showing on the screen. For example, if I had a red, white and purple background, it would show red, white and purple lines across the screen. The tablet is still fully responsive even when this is going on (can still pull down the menu, touch to turn off, etc.). Sometimes just turning the screen off and back on gets it working right again, sometimes it takes a few taps on the back to the tablet. But once its working again, it stays working until the screen is off again for awhile.
I can use the tablet for hours with everything functioning as it should (using it now to type this post). After leaving it for an hour or two, I wake it up by pressing either the home or power key and the lines will be back. Even if it's shut down for a while, when I turn it back on the lines are back, and they appear right from boot, or even when off and charging, the green battery charging icon turns into green horizontal lines.
I've already cleared the cache, it was just factory reset, I've had the back off, disconnected the battery and reseated what I think were the screen connectors.
Any thoughts as to what is wrong and how I might fix it would be appreciated. It's a Note 8, 4.4.2, stock, not rooted.

I think it needs service, it's a hardware problem
You can use a HDMI adapter to connect to a TV or using Screen Mirroring Function to see the display on TV. If it's normal on TV, your LCD is defective or the LCD cable gets loose.
In order to get the LCD cable, your main board has to be removed as the LCD lies under it.
Hi all. Complete newby here so please bare with me. I have an Xtrons TD626a head unit which I have found out is an MTCB rk3066, 4.4.2
I have managed to install the Malaysk rom and very happy with it but it still hasn't solved my problem, that being the illumination colour of the physical buttons around the screen. I've searched but cannot find a similar problem so let me explain.
Turn head unit on from standby - blue illuminated buttons.
Enter settings - element - choose a different colour and the buttons change to that colour + blue for 2 seconds then revert back to all blue again. For instance, if I pick white, I get white for 2 seconds then back to blue. If I choose red, I get purple for 2 seconds then back to blue. If I choose green, I get cyan for 2 seconds, then back to blue. If I pick blue, I get blue.
If I enter the factory settings (enter 126 then choose other) I can pick R, G, B or RGB. Anything other than RGB removes the element option in the standard settings menu, but regardless of which colour I choose in factory settings, I still only get blue.
If I choose white in the element setting I get as said above white for 2 seconds then back to blue. Then leave settings and go back to main menu and the buttons stay blue. If I then power off having left the element setting as white, when powering down the buttons go white until it switches off. If I then power up the unit the buttons are white until it boots up where they then revert to all blue again. This was the problem before and after the Malaysk root so it's nothing to do with that but it still must be a software issue because the capability to change the led colour is possible briefly. I remeoved the front face and witnessed the led's changing and reverting back.
PLEASE HELP !! all my dash is red orwhich with these awful blue head unit buttons spoiling the view!

Hi Guys,
Everytime I press the top part of my screen (front cam, ear piece part) the screen flickers and sometimes it shows a horizontal line anywhere on the screen and it only happens when i press the top part screen.
I ran a LCD test using #*808# and the screen is fine. It's just happens when pressing the top part of the screen. Even when I'm in the recovery mode and pressing the top part of the screen it still shows lines and flickers.
You guys think it's a hardware problem already that something might be loose connection on the motherboard?
Tia guys!

It looks like a hardware issue.
Hello
i installed lineage 16 and i saw there is black screen issue. so i downgrade version to 15.1 and i still seeing black screen issue.
lemme explain black screen
all turns full black no background lightning, when i open screen turns black, only way to get rid of is lock screen and open screen. its really annoying.
also i noticed something. when black screen ups back button home button and menu button lights become on.
my device t810 lineage 15.1
I have a moto g5s xt1792 after I unbrick trying to install lineage, almost everything is working the problem is the lock screen, after a while the screen goes black, it lights up (with the black screen) I can unlock the screen but if it is just the pin or the pattern the screen remains black after unlocking the screen, if it is with the fingerprint it goes back to normal and I can see things.
there is another problem related to the sensor, the screen does not light up when i pick up the cell phone i have to press the power button for the screen to light up
the stockrom I installed is this one
MONTANA_OPPS28.65_37_7_11_cid50_subsidy_DEFAULT_regulatory_NO_ERASE_MODEMST_CFC.xml
and then I reinstalled this one because I noticed the screen lock problem but it continues
MONTANA OPP28 65-37-7 cid50 subsidy-DEFAULT regulatory-DEFAULT CFC
sorry the bad english and thanks for the attention
--edit--
the black screen appears after a long time or randomly after i lock the screen
I noticed something too, the black screen disappears after I keep pressing the power button to light up the screen a few times and then the screen shows the screen lock
