Hello,after replacing the display (by myself) , I' m not able to adjust the brightness of my display. It's stuck on the lowest level. Things I've tried;
- Called with HTC
- Performed hard reset
- Set the brightness to "auto"
- To adjust it with a brightness widget on my homescreen
- Replaced it with another display
- And of course digging through XDA
Specs;
- Desire Z 2.3.3,sense 2.1,unrooted
When I try to adjust it to the max.level it does not give an error. It just stays on the lowest level.
Is there anyone with the same problem or better,has a solution?
Many thanks in advance!
Can't adjust brightness either...kinda sucks
I am also having this issue and would appreciate any insight.
Did you guys do the work yourselves?
Yes,together with a video on "repair universe" I changed the display by myself (twice). Still having the same problem.
Anyone
Brightness stuck on highest setting
I also have this same problem. I just replaced the lcd display myself yesterday on my G2 with the help of the repair universe video. My display brightness is stuck on the highest level. When I try to adjust the brightness, only the buttons on the bottom of my screen (home, menu, back, search) change brightness but not the display.
I'm currently running ILWT CM7 297.
I'm going to try re-flashing my radio and then wiping and flashing a new ROM.
If anyone knows how to fix this please help!
I suspect it is hardware related such as the ribbon cable or screen is missing a lead for the dimming function. Can't tell from here though sorry.

I tend to second this opinion from killj0y.
Have you tried making sure the ribbon cables are tight and secure? Sounds like the ribbon cable from the screen may be loose.

Also is it the original ribbon?
Any updates
Has anyone figured out the answer to this? I just replaced the LCD from RepairsUniverse.com as well and the same thing. The brightness is low and won't change at all. Everything was fine before and RepairsUniverse.com says it's the motherboard. If the motherboard was fine before and all of us are having pretty much the same problem and some (or all?) of us got the replacement from RepairsUniverse.com, does anyone else smell a rat?
I know nothing of this company but depending on you screen problem, I wouldn't assume your mb is perfectly fine.

Has anyone fixed this problem? I have the exact symptoms, this is the second one I've tried, could it be because the lcd isnt oem? Please help
Hi. Are there any updates to this proble. I recently had the screen replaced on my Desire S and now it is stuck on the lowest brightness settings. Change any of the brightness controls does nothing. I took it back to the shop and they tried another screen, but still have the same problem. The motherboard was also replaced and the problem was there, but reversed...!? The screen was then stuck on full brightness...
Back to the original motherboard and the brightness is back stuck on lowest brightness setting....
Unrooted, Stock ROM

Hi all.
I'm reading a lot about 'screen flicker'. But it seems people are using this to describe a few different faults.
I've noticed that my one x backlight flickers when in auto brightness mode. But it only does it under artificial light. Under natural light it's totally fine.
If I turn off Auto brightness, it is completely fine also, regardless of what level I set the brightness to.
It's almost as if the software isn't filtering the auto brightness sensor output enough and trying to respond instantaneously to even the slightest light change, giving the impression of a flicker.
Who else has this issue specifically?
It looks to me like a software issue, but I only have 3 days left in my return for refund peiod and I'm not sure what the best option is.
Cheers.
EDIT: On to my 10th handset now with the same issue and just about ready to give up, but have noticed that the flicker seems to be worse when the CPU is coming on and off heavy load.
Can someone with Root and SETCPU installed please try different governers to see if they make any difference to this issue? I don't wan to root this phone to try it myself as I may end up returning it. Thanks!

Oh well return it, and buy a new one thats probably the best option, i ordered mine yesterday, and ill do the same in 2 weeks if it have issues
Yeah I'm thinking that might be the best option. It's just that it seems to be a Software issue to me.
Anyone upgraded to 1.28 and seen this specific problem (not the screen jumping and flickering pixels) go away?

I've upgraded to 1.28 and still have the flickering problem. I would love to be able to believe its software and its going to get fixed with an OTA, but at the moment everyone is simply uncertain as to what the future holds.
HTC advices anyone with a flickering screen to go to your carrier and ask for a replacement

On to my 10th handset with auto-brightness flicker now. At what point should i jsut give up? lol
It seems to be somehow related to CPU load also as I'm noticing the flicker is far worse when the cpu is changing power states.
Can someone with root try a different governer for the CPU and see if that changes the flicker at all?
BUMP. I'd be really great if someone rooted could test this theory!
..
I really cant help but ill tell my experience with my onex for the past two or three weeks.
I had the flickering screen twice,
1. random on the notification bar.
2. I was taking photos and got the CPU loaded because I was shooting too many pics. the bottom side of the screen was flickering.
anyway, I notice that the flickering only happend when the auto screen rotate is enabled.
Thanks for the reply, but I think you're talking about a different flicker. I'm talking about the back-light flicker when Auto Brightness is enabled. Not the LCD panel flicker.
The display of the phone just sits at the lowest brightness.
Automatic brightness is not working and on a white background can be seen flickering.
I changed to lcd with new one but the problem remained.
The new screen is reacts the same way.
Аnyone encountered a similar problem?
The same here

Hi folks,
I am facing the same problem, does anyone know anything about it?
Thanks.
Have you tried doing this?
Thanks for your help.
In fact I have an Desire HD and is running stock ROM, I have tested on different LCDs but still the same: low dimm, luminosity sensor not working, I tried but the brightness can not be adjusted, not change at all.
I am suspecting that might be a logic board problem, but I am not sure, this is not software for sure.
I have tried 4 displays and the problem is not solved.

Hey guys,
I bought a HOX with a broken touchscreen. I changed the whole display unit and that is fine now, but I had flickering backlight before and after changing the display unit.
I noticed this was a common error earlier, but I don't know if it still is? Is there any fix to it? I read that it was fixed back in october or so and my version is:
4.1.1
software number 3.14.207.27
sdk api 4.63
kernel 3.1.10-g946d78d
[email protected] #1
Can I fix it by flashing another kernel /ROM?
This is what I see:
I can't change display brightness. It doesn't matter whether I do "automatic", lowest or highest, nothing changes.
When It is charging: No or only light flickering
When it is not charging: If I do nothing at all, there is no flickering. as soon as I touch the screen or it has to process something, I have a light increase/decrease in brightness.
The backlight is NOT dead. It is only pretty low. I can still see if the room is dark and even when there is light shining in the room.
I am just bothered by not being able to adjust brightness and the flickering when not charging..
I have done a factory reset via bootmanager but it still is the same.
But I REALY like this phone so I'd realy love to keep it.
Any help?
I have no problems with flashing as I have flashed previous mobiles, but I would like to know whether there is a ROM/kernel that will fix this.
for example when I have the analog clock on the screen and it starts ticking forward each second, as soon as it starts moving, the screen goes darker a tiny bit.
I hace the same problemas. Did you fixed this issue?
Dont bother yourself with it, its not a problem, its very common, all one x's i handled had the same "issue", my current one also has it, just ignore it or put brightness around 50%, much less noticable
It has to do with tegra 3.

I have investigated this further and came to a conclusion that this is something called smartdimmer, connected to tegra 3. I now just want to find out how to disable it ^^

Are you sure it's a hardware issue (OK sound stupid but it's easiest to check if it's a software issue)? Try a couple of different ROMs, from the latest CM10.1 test builds all the way to rock hard stable CM7 and stock ROMs. It's interesting that soft key light is being changed though; did you mix up some wires or something? Also, not to insult your intelligence but you have turned off autobrightness, haven't you?

Sorry i forgot to mention those things... i already tried many roms, still the problem persist. and i dont think that i mixed up the wires cause it doesnt have much wire connections in the ribbon cable and they are just plug in type so we cant make wrong in the connections.
Even tried external apps to control the brightness... still the soft key ligh is adjusted not the screen brightness

in that thread you mentioned about increasing the brightness... what about the lowering the level?
i tried those codes...but nothing happened
I'm doubting it is software then, you have tried different ROMs and manually changing brightness so I will assume you need to replace your LCD. Being I have never seen this issue before this is just my best guess and what makes sense to me. It is doubtful that the flex is causing this issue and the screen itself is to blame

i dont think that the lcd is defective...i think my new ribbon cable is not supporting this,...but i dont know how and why?? (might be its because made in china?)
can i change the brightness level thru build. prop editor?
its very possible but it really doesnt make sense how the cable wont support it, do you have your old to test against?
and i doubt build.prop will change a thing as we have already attempted manually changing it and it appears to be hardware

yes am having the old one, but its fault is about the display..so cant use that any more... i tried to figure out the brightness option in build prop, but i cant find that option...can u help me on this?
truthfully i dont know of anything in build.prop that would be changed to change brightness level, ill dig around in a bit but nothing off the top of my head.
but again if using adb to change brightness or any other manual method wont change then there is a hardware fault somewhere as this happens across all roms.
i guess i never asked, is the screen the same brightness in recovery and bootloader?
if so you will need either a new lcd or flex cable
but in general even if we use low brightness in phone, while getting into recovery or bootmenu it will be in normal brightnes..i think so,....so i dont find any difference in brightness level at recovery page..but do we have options to change brightness level in recovery mode?
That would be coded into your recovery and bootloader respectively, I couldn't say how esay that would be to change, probably near impossible in hboot and still hard in recovery. Don't know the brigtness value in them but I assume high
I guess there is an off chance a sensor is malfunctioning, download z device test from market and test them, but this shouldn't be a symptom of a bad sensor.
Really you need to find out what hardware to change

Hi,
Factory reset - done!
Flash Android 2.3 - done!
I had the original Android 2.2 before, so the software is not the reason for my HTC Wildfire display problem.
Display image is moving up/down, the line of notification with signal, battery level..., is going in the middle, bottom of display and so on.... I have a screenshoot and a picture made with a very bad mobile camera, but hope to be enough!
I think few water drops inside 3.5 mm audio jack could be the reason, the warning LED(red one) is not working too.
Had someone the same issue? A way to fix this?

...menu bar is floating from bottom to top, pushing all icons/options and it is nearly impossible to hit the right icon/option. Also when there is a keyboard, it moves up and down but it always reacts when pressed on position where it should normaly stand.
Thanks! So... I'm not the only one with this issue.
I think the reason for this screen it's because i dropped the phone before (3-4 days), but not noticed this right in that moment...
Anyway, I easy dropped the phone with intention several times recetly and the screen was OK for a day... don't know what can it be...
I'll try to find out how can be this problem fixed in a service and how much have to pay for all this...
After all, it seems my display don't want to turn on anymore.
I turned on my phone and it's working, it's able to receive calls with no problem, digitizer is working too because I can answer by tapping the known part of display where is that button!
I want to buy a new display and replace it. Could be anything else that make my display not turning on?
