Hi guys,
I have a Redmi Note 4 Snapdragon with a screen replaced recently. The problem is the screen only works after the phone is booted, if I let the screen turn off, it can't be waken up again. There's still backlight, vibration and all and I still hear sound. Which means the touch does work, only the screen doesn't display anything, just black. What can be the cause of this? Thanks everyone!
I have exactly the same problem on a Redmi Note 2. And this problem is not so rare because i found a few posts with same symptoms but i cannot find a fix. If you please find, please let me know.
Can I ask you something cause I'm a technician and I face similar problem not exactly the same. Were your screens bought with frame already glued and you face that issue? Usually such issues occur when they is no duct tape (sorry for my English) at the lcd flex cable where it folds under the frame or where the backlight circuit (I don't know the correct explanation in English I hope you understand). So I needed at my phone to replace the frame as well that's why I bought a lcd with frame (that of course was terribly glued). My issue is blacklight flickering when it wakes from sleep and if I push the edges it's ok. I have replaced a lot of note 3 LCDs without frame and I know that in all of them I had to put duct tape to make them work properly and without issues, I had only one for note 3 pro SE that was properly made. So I believe both your issues as well as mine have to do with that. If you have the broken ones, take apart the new and check side by side the flex cables and if you find exposed connections compared to the original just put duct tape.

Perhaps you might want to enlighten us as to which ROM are you using, and who is the manufacturer of the lcd display?

Hi, I'm using the Ressurection Remix ROM on Android 7.1.2, planning to update to Oreo soon with the Pixel Experience ROM. And the LCD manufacturer is Tralfagar.

Well, I don't know about Trafalgar - but if the new display is has an ebbg chipset, then you may have problems. There have been issues with ebbg displays and TWRP (when using custom ROMs - see for example https://forum.xda-developers.com/re...redmi-note-t3716706/post74815338#post74815338). Does everything work properly when you reboot to TWRP recovery? If not, then this may be the problem - and you may need to change your ROM to the latest MIUI releases.
I am facing same problem
I have redmi note5/5+, using custom rom (ion), I am facing same problem, changed lcd two time, tried with other roms, but nothing improved, did you find any solution.
Hello,
I have the Redmi Note 4x and the device is getting worm in one location where the home button is when the screen is on, when it off the temperature returns to normal. Also it began 2 days ago and I didn't experience it before.
All the rest of the screen doesn't heat up at all.
Does it sound right? or is there something I can do?
Thanks
Hi.
I was wondering, I recently replaced my LCD and frame in my redmi note 4x.
It's working lovely apart from it won't wake up on double tap now and the home buttons are dim.
Anyone have any thoughts???!
Thanks
Since you are experiencing issues after a hardware change. I would suggest that you start by opening the phone again, check and re-seat all of the connectors. It may just be as simple as a poor connection.

Just seems strange the screen works perfect but won't wake double tapping
Redmi8a (dual) , screen is getting dimmed when phone heats up while exposed to sun , the same issue i experienced in redmi7a which i returned , turns out 8a dual have the same issue. I don't know if this is some kind of protective mechanism to keep the phone from overheating. Brightness comes to normal when device cools down. It bugs me even more because i cannot recall facing the same problem in my earlier redmi 3s.

Hello everyone and thanks in advance for your help,
I have a Xiaomi Redmi note 4 snapdragon (mido), my problem is I face ghost touch. I have it in any AOSP android 11 roms and the original MIUI rom and it happens in every screen, even TWRP.
I tried every solution cleaning screen, disabling auto brightness, cleaning touch and LCD flat connector and so on. only solution that works is: using an electric igniter of a cigarette lighter I give a electric shock directly on the display, and it completely goes away, but for a while. then it slowly comes back again as if somehow static electricity builds up somewhere in touch screen.
Has anyone faced this problem, and is there any solution apart from changing LCD?
