PX6 STRANGE ISSUES. HELP! - MTCD Android Head Units General

Hi there,
I purchased a PX6 for my 2009 Honda Civic last June and I’ve been having issues ever since I bought it.
The screen is generally heavily distorted, making the graphics look washed out and strangely warped. Occasionally, it will correct itself and look normal but it usually takes a bit of warming up/driving to correct it. Audio through CarPlay will frequently stop playing which only returns when I switch to the radio for an extended period of time. My back camera is also intermittent.
I’m starting to think it may be a power issue? I’ve also noticed certain lights in my car often don’t light up. The gearstick, AC buttons etc. I tested the battery I installed in my car, which came to 12.86 volts. Since updating the HMC a couple days back, I noticed it now displays the battery output in the menu bar. In the image attached, it’s showing 14 volts in the menu bar and when the screen randomly works correctly, the voltage is at around 13 volts. However, this is not conclusive evidence - as I’ve only just updated the software.
If anyone could please advise, I’d greatly appreciate your help.
Thanks,
Danny.

Can no one help me with this?

What happens if you turn the screen brightness down a little bit? Does adjusting brightness make the problem worse, or no change?

No changes at all. Exactly the same.

Have you contacted the seller or manufacturer? If it has never worked right, then I would be looking to replace. If it was purchased on Amazon, I'd suggest return or exchange. I know it's probably not the help you are looking for on the forum, sorry.

Have Screen Burn In? Warranty It, Get a New One

Searched, didn't see a similar topic.
If you had Android Wear 1.0 through about 1.2 on your phone, your Moto 360 had a much brighter charging watch face. That much brighter charging screen was actually causing burn-in on your OLED.
You can see if yours is affected by opening the Settings app. If you can see a ring of the charging halo in the background, your phone was damaged by this.
Fortunately, Motorola is honoring this as a warranty issue - you just have to claim it before your one year warranty is up. I now have a brand new first-gen Moto 360 - with an improved watch band clasp too.
Hi, where did you submit request for service?
I got mine warranty replaced (for this issue) by calling Motorola technical support. Despite being clearly outsourced, they seemed to be well aware of this issue - and processed it without too much futile troubleshooting.
moto 360 has an LCD Display , not an OLED!
I have burn-in too. It's most noticeable on white backgrounds as a yellowish ring. I only noticed it recently but I think my warranty might be up. Didn't think an LCD could have burn in, but there it is...
Could someone post a picture of the burn-in? I want to see how bad it actually is.
I took these with my watch at max brightness. Normally, it's more subtle. It's a yellow ring that's strongest at the 3 o'clock position, and decreases clockwise -- exactly where the charging ring would start.

In person, the white backgrounds actually look the worst. I have a nice white watch face that I simply won't use because of this.
I mostly use dark watch faces though so I don't notice it. It's invisible on black and most of the Moto stock faces (e.g. Dials).

how can LCD get burn-in? that's so weird

After images? (for lack of a better term to use)

Anyone else experiencing this red after image thingy on the sides of the screen? It is most noticable when looking at a dark image or completely black. See image below and notice the sides.

I mentioned after images because the icons on the status bar sometimes shows an "after image" when for example I toggle the wifi off thereby the wifi icon disappearing, an after image is left behind but not that noticeable.
Any thoughts as to what it is and possible remedy?
I've noticed this also on mine. If I'm right , I get this red tint on the right side of my screen, after I play that football game on Messenger. It seems to go away after a while. It's noticeable on grey colours.
thats called burn in and thats a hardware issue.
That's a screen burn if I'm not wrong. Even I had experienced the same and the device was under warranty so got the screen changed and it was all fine until now, 10 months after the change, that it's back again. I'm thinking of switching to Nexus 6P now.

I was thinking of having it replaced since it is still under warranty but after reading your post, should I still go for it?

Here what happens with my device : When I shoot up the brightness to the fullest, those "red after images" kind of dissappear. But then again when the auto brightness is switched on it returns back (pssst... LG G4's are haunted! ?). I don't know what exactly the problem is, whether with the digitizer or screen. I would still suggest to get the screen changed as it's still in the warranty or if you don't want to take the pain switch to some better phone.

HTC One M8 doesnt want to turn on/weird disk problem

Hey there.
I have a problem with my HTC One M8. First of all, I have slightly damaged the screen in the upper right corner and it has a black spot, like 3-4 weeks ago. Because of the fact I am on my vacations and I am 24/7 on move, I don't have time to fix it and it's not that much of a problem as the phone was 100% functional with that issue - the screen reacts to touch in that black spot. But let's get straight to the real issue. Yesterday, before going bed, my phone had 20% battery. I am used to fall asleep watching some vids/other stuff @ Youtube and so it was @ yesterday's night. When I woke up, my battery was dead so naturally I plugged the adapter to charge it. What struck me was the fact that the screen didn't react to charging. I tried switching to other adapters but no result. I tried to turn on the phone anyway - if the screen is messed up, the phone should turn on anyway and greet me with some sound - it did not. I borrowed my friends laptop and connected the phone to it in order to find out what's going on. The moment I plugged it in and it installed some usb drivers, the laptop didnt display 2 disks (the phone itself + the sd card) but plenty of disks (D-Z) which the laptop wanted to format immediately (havent done that - last resort move). I have installed the HTC Sync Manager but it doesnt find the phone. It may be due to the screen damage, however, I strongly doubt that and I think it's some software issue. Has anybody had such a problem? What should I do? What kinds of software shall I download to try to tackle this issue?

Thanks in advance for any answer.
My android version is 4.4.4.
Soft version 3.28.401.9
HTC SDK API 6.25
Compilation 3.2.8.401.9 CL389833
Not branded
Let the phone charge for several hours, then hold Power+Vol up for a minute or more , and see if there is any change.

OP3 Rectangular part of Digitizer Unresponsive

CAUSE I AM A NEW USER, COULDN'T POST THE IMAGE IN HERE, SO SEE MY REPLY AT https://forum.xda-developers.com/showpost.php?p=73388497&postcount=2
What i think could have caused this is the charging at home, cause devices connected to certain outlets in my house sometimes have a lot of static electricity in them (voltage fluctuation maybe?) e.g. sometimes the digitizer became unresponsive when connected to the charger + The metallic back filled with static to the point you can't hold the bare phone in the hand anymore, but some other times it was completely fine
PS. The phone has been dropped only once, and that was back in December
All the rest of the digitizer works absolutely fine, and I wouldn't really say it's completely unresponsive, it does respond to my touches but as can be seen in the pic, whenever i touch that rectangular part, it instead registers two touches above and below that region, instead of in that rectangular region.
This initially started happening like a month ago, shortly after i installed OB19, thought it was some software bug, updating to OB20 and then 21 didn't help, i did dirty flashed 4.1.6 and i think it worked for a short while on it(don't really recall correctly now cause i immediately went back to OB because systems app didn't worl cuase of dirty flash)
And after that, things that i have tried and didn't work:
Revert to 4.1.3(Clean Flash)
Revert to 4.1.0(Clean Flash)
Install LOS with firmware from OB19(Clean Flash)
Completely draining the phone twice
What i haven't tried:
Install some older LOS build with old firmware that I know didn't have this problem(e.g 4.1.0)
Currently on 4.1.6 after clean flashing; and the issue also occurs in TWRP too, so i guess it's RIP for the digitizer? Or is this fixable, couldn't find much info about it on XDA/reddit/random forums, not really a common issue i think, did find some threads though but those were from 2011-2013 mostly

The exact same thing happened to me last year. I ended up sending it in to get it repaired under their insurance :/ I tried everything to get it fixed and absolutely nothing worked

Display issue - not sure what the problem is

I had my phone plugged into the charger and when I turned it on I got this screen. When I reboot, I don't see the boot up screen logo , it just takes me to this screen and I see this big block of white. Any idea what the issue may be?

Try forcing a reboot by holding voldown+power. Let me know if it doesn't work.

Unfortunately its the first thing I did. It doesn't boot with the samesung log, instead with a white screen as above but I see some of the text behind it (like asking for pin number etc)
Will it go into the boot menu?
nope
That really sucks... sorry to hear this. Happens on the S series phones apparently too.
A loose display ribbon connector... maybe.
Looks like a blown display.
Did it recieve any hard impacts?
Always use a good case like the Zizo Bolt.
If so and it was me I would replace the display or order a new N10+ N975U1, they are still available. Almost all of these are loaded with Q.
Personally I refuse to run Android 11 or higher.
If you don't object to Android 11 you can find them used for about the price to replace the display.
Samsung simply doesn't have any other flagship phone that I would buy over the N10+ including the S23U. I have a known good US vendor that sells new ones for $650 which is about twice that of a used one. Bought one from them about 14 months ago. Pristine in the factory sealed box. He buys up unsold lots. The last manufacturer ones were factory loaded with Q.
