20 min later i had a phone call but i did not hear the opponent.
after a resarted everything work fine for 1h.
after i pluged in the charger the screen went black.
since then i tryed several things like unplug-plug, press start button long also tried startbutton+ volume down..........
what i belive so far is that the mobile does everithing right without showing it on the display.
the display gets dark gray (from black) when i swich ist on. the start android vibration comes normaly and when i let it start long enough i hear the fingerprint working and when i dobblepress the start button the camaera swiches on.
do you think this is hardware or software?
and what shoud i do next?
it is a lemax2 6gb 820 with twrp and oreo
and thx for any help i get

hello again,
i am sure now that the phone starts android normaly because my smartwatch schows me the new whatsapp massages.
interestingly whatsapp said that my clock does not fit any more to my country!
The screen hase 3 diffenent shades of gray.
black when switcht off
dark grey when i swicht the mobile on
and somtimes a much brighter gray during starting android.
BUT: the screen is gray since the hole day
even if i go to recovery.
can it still be a software problem? because if it is a hardware defect i would send it back for warranty.

update
i flashed now twrp again from my PC via ADB.

It really sounds like a hard ware problem. Probably the shades are just from the backlight on the display. I guess the display itself is broken or something. Can you get to the recovery mode? If you don't see it just use your warranty.

no, also recovery stays gray.
and yes, the gray looks like backlight.
do you think that i should try to flash it back to normal bootloader befor and send it back?
can they say that the screen brocke because of the flashed rom?

HD2 No Screen

Qeustion
My HD screen is off, and i cant seem to get it on again.
I just was working on it 1hour ago, took it out of my pocket and see that i have no screen.
Rebooted the phone, but no succes .. i see the screen turning on, but it light-gray (backlight) but no actual info/colors etc, also tryd a soft reset, no succes.
I have the Energy ROM Com5 build from 8July with the new 2.12 radio rom.
Could it be that in some way the screen died?
Hope someone can help me, im @ work now so i cant connect it with the PC.
When im home im planning to reflash the device ..
Thanks!
Weird
I just pressed a button and the screen turned on, and the colours/info just slowely fade away ... weird.
Could it be that the touchscreen is not oke anymore?
Or could it be a problem in the radio/rom i use? (and therefore a reflash could fix this?)
Hope its a easy sollution, otherwise ill be flashing it to stock and get it fixed by HTC.
Very very strange.
It seems to work again.
Anyone think i should reflash it to stock and try get a new one?
Are these signs of a screen going defect?
I dont know, first phone for me with touchscreen.
I would suspect a faulty screen, if it is still within warranty i would deffinately get a new one, however yes, try going back to stock first, see if it helps, it may be just a bad flash.
screen problem
I've had this and similar problems with my HD2, now on the 5th replacement from HTC in just 6 months of owning the phone. I also had the same problem on my HTC HD previously. Press the power key and just the buttons at the bottom light up but no response from the screen. Also had exactly the same problem your experiencing where you can faintly see the screen but not lit up. Flash it to stock rom and return to HTC for repair.
BEWARE!!! take some pics with date stamps of your handset before returning. They sent me 3 handsets all with the glass front panel not fitted correctly. Check the return handset carefully, you should be able to feel a lip between the casing and the screen as the screen is set a fraction lower than the casing. THis should be uniform all around. They tried telling me that i had damaged it myself despite calling them as soon as the handset had been delivered back to me.

That's 'sleep of death', which affects loads of htc devices.
Oke i will stock it soon and return for repair.
I think its idd a screen problem, cause when the screen isnt functioning anymore, and when i put my ear on the glass, i hear a little squishing sound, like air is escaping .. it doesnt do that when the screen shows info/colour.

It;s there something to try before trow it? Thanks in advance for any ideea!

I hate to say this and I hope I am wrong, but sounds like from the way you describe it that your screen has overheated and actually burned out.
Can you get anything to light up? HTC splash screen? No?
Is it under warranty?

nothing on the screen. do you think it's the screen or the mainboard? because I can see the buttons light and backlight and vibration when I power it up, but the screen is black allways. If I change the screen can I make it work?
no warranty, because it's bought from france and I am not living there.
Thank you so much for your help!

If you have any experience with taking phones apart, try to reconnect the display connector.
It could be something as simple as that.
However, if that doesn't work, it probably is the screen.
As Zcink said, it may not be worth repairing since it's going to add up to the price of a new phone.

From sleep to lockscreen LCD blank problem,any solution?

Hello.
When I leave my phone in sleep mode (screen locked and light off) and try to wake with On/Off button, sometimes I get a black screen with a faintly image. The touchscreen works and all the buttons, and if you click 2 times On/Off button - the image appears all ok. I tried to flash another stock ROM - all the same. Then I`ve unlocked the bootloader, rooted the phone and even did the S-off with wire trick (1.53 Hboot). Then I`ve tried 3-4 custom ROMs with 6-7 different kernels, from stock to custom, but all the same. Yes, I`ve updated the firmware file, also, but with no difference.
Well, I see that this problem is not so usual, but I couldn`t find any real solution. Did anyone have this kind of problem and solved it? Since I got this phone from another country - official warranty is out of the question, I need a DIY solution.
Any help is greatly appreciated.
THX in advance!!!
I would have to say it looks like the light for your screen is dying, I had my screen replaced once, my screen would flicker from very dark to very bright

hmmmm, but when I get the OK image - it doesn`t flicker or go from dark to bright, it only has trouble to "wake up from sleep mode". even when i relock the screen quickly and don`t leave it unused for 2-3 minutes, the screen works OK every time....it looks like a software problem, but still I didn`t manage to fix it with all the ROMs/kernels/firmwares I`ve flashed....

Thinking about how to troubleshoot if hardware or software. When in sleep mode, instead of using the power button, I would have the phone plugged into a computer and use the " adb reboot " command to reboot the phone without touching the phone a few times and see if it lights up correctly. The first thing you should see is the boot screen, and if it works every time, then you do have an issue with your firmware. If you don't see that boot screen first every time, then as much as it sucks, I would guess there is a hardware issue.
Good luck, but this is the easiest way I know of to help determine what the issue likely is.
Minor update here, the first thing (at least on mine) that I see is the lock screen for just a quick second or two, then it quickly goes into the boot sequence. This is important as in "sleep" the ROM is running, so if the first thing you see is the boot sequence every time, and not the lock screen, then it points more to a software problem than a hardware issue. CM9 had an issue for the epic4g where you had to turn it off and on sometimes to get the keyboard to light. They found the issue in the firmware causing it.
Just wanted to make this as accurate as possible.
Wow so I am not the only person with this problem. The EVO 3D that I have was replacement phone that was given to me from Sprint from the first EVO 3D that I had which had issues with the digitizer. I received the replacement phone this past Tuesday and it worked fine for two days. It was not rooted and I did install the ICS update. On Friday morning I took it off the charger and went to work, while in the break room the screen suddenly went black and I could not get the phone to display anything after that. The Android function buttons at the bottom will light up but the screen wont, the phone also gets hot even with it powered off.
Long story short, I took it back to the Sprint store where they ordered me yet another replacement EVO 3D. Has anyone had to go through 3 EVO 3Ds or more?

Excellent thinking, I didn't think in that direction. I'll try this tomorow, since I'm not at home. My personal oppinion that it's a software problem but if I did all the above - what did I miss? If I flashed the firmware, ROM and kernel, what else is left untouched that could affect the LCD? Could anyone suggest a good kernel? Or can I downgrade the firmware, since no one had such a problem with GB?
just to inform all - I tried all soft solutions, but all the samo. finaly - I replaced the LCD and everything is OK.
THX all for help

Screen doesnt wakeup any more / Only restart helps

Hey,
i am having some trouble with my Le Max 2. My screen does not wake up anymore, but the phone is still active. This especially takes place, when the screen is off for more than 5 minutes or so. Then i only get a black screen and hear the unlocking noise, but i cannot see the content any more. Backlight is working, but only a black screen. Whatsapp Web, etc. still works when the screen wont turn on. The only thing i can do then is to press the power for 10s to force a restart. Then everything works like a charm until the screen is of for a specific time.
I already flashed new ROMs (RR Nougat, MIUI Marshmallow) both dirty and clean. Also did multiple full wipes. problem is still there. Anybody of you already had something similar?
Do you think its HW or SW related?
Thank you so much

Have you tried to change your firmware? Kernel? Try going back to stock?

I tried going back to stock. But i am pretty sure now its some HW issue. The screen just wont turn on when the phone itself is cold. When i pull it out of my pocket and its kinda warm, it works like a charm.
But if it is sitting on the table / i have it in my hands outside - the screen wont turn on anymore. If its too cold it wont even reboot...
Stange problem - could there be any loose solderings or something?

I have no idea about that. Sorry.
Especially since it was fine, and is hit and miss with the problem.
Is it within warranty?

XZ1 dropped

Hi to all!
I have a problem with my phone. I dropped my XZ1 from a high level, luckily the phone does not have any scratch etc, but when i am trying to boot the phone, the phone shows the Android and XPERIA logo, shows 3 dots in a grey background and the screen goes black.
I tried to repair it with Xperia Companion but nothing happens. Also, i tried to flash it, everything goes smooth but again when i boot the phone after the flashing, the phone shows the Android and XPERIA logo, 3 black dots in a grey background and the screen goes black.
Does this happened to anyone? Is there any workaround for this issue?
Many thanks in advance.
P.S. I tried to fix it in a repair shop, and the clerk had no idea how to fix it.

there seems to be damage to the screen
Have you ever tried to replace the screen with a new one?
if that doesn't work, there may have to replace one part of the engine .
