Keys don't light up - Desire HD Q&A, Help & Troubleshooting

Hey there,
my screen was broken and i fixed it by myself (i had no warranty anymore, so...)
Screen is working well now, but the keys on the bottom won't light up.
Anyone has experience with that and could give me a tip, what i could do?
Thanks,
Prexx

I am using Miui, and there are settings to manually calibrate brightness levels and key light levels. You should check that out

My first guess is that you somehow accidentally might have disconnected a cable which leads to the lights. You might want to open it up again and recheck all connections.

check if its a hardware prob or software try several roms of the same results i suggest u fixe the light prob in any htc center

Turn off Flashing LED's

WHen I'm driving my car at night the flashing lights, on my Blue Angel are very off putting.
If it possible to disable the Blue (Blue tooth LED) and Green signal LED, but still have Blue tooth and us the phone?
To turn off the Blue LED from coming on with Bluetooth go to:
1. Hkey_Local_Machine/Drivers/Builtin/BWLEDMGR
1a. Change the Index value below it to "0" it is currently set to "1
Soft Reset and the Blue LED will not turn on.
Here is a revised procedure for turning the Green LED off. Cabrio came up with this.
2. To keep the Green LED from flashing or coming on at all go to
Hkey_Local_Machine/Drivers/Builtin/NLEDMGR leave the dll name as NLEDMgr.dll
2a. Change the Index value below it to "0" it is currently set to "1".
This seems to completely shut off the LED and keeps it from getting called up.
Make sure you soft reset after making the reg. change.
Do this at your own risk.
I am working on a proggie that will allow you to turn off the LEDs at will, and also turn them back on.
Stay tuned...
OMG the *flashing* is so annoying.
It can be on or off (I dont care) just wtf does it have to flash?
Agreed in the strongest way. LEDs as OEM have delivered the device are terrible. I don't like to sleep with a police car in my room! LED should be entirely user conifigurable as to what solid or blinking means or if they are used at all. The registry changes above seem to work fine for me. It would be ineresting to know what other values for these registry entries do (if anything)
Any new info on this subject?
The only ones who like it in my house are my cats, and i like me sleep to much to let it continue
Yes if you change the Registery Settings, as described above it all works :lol:
One solution:
Use tweaks2k2.Best software having abt 92 safe and reliable registry tweaks.It has the option of turning on/off leds,also increasing the keyboard light time :lol:

thanks! you forgot to mention the link to the program

Version 3.6.0 released today includes part of the trick for HTC Magician.
hey happygoat, hows ur program coming along?
Actually this technique listed (registry hack) only partially works.
I noticed to my rather large annoyance that it started flashing again while I was sleeping. There are other times when its start flashing as well, eg if you disconnect ActiveSync in progress.
This is unbelievable! Removing the LEDs cut my time to connect to the WLAN from turn on in half, from 12 to 6 seconds! Most of it seems to be that it starts connection attempts almost at once. Also the range is improved! Anybody know how this is possible?

has anyone tested the battery life? :wink:
Not me. That's not one of my concerns. But I can say that the unit is also a lot more responsive when turned on. It has annoyed me that the first 5-10 seconds I couldn't do much with it. Now it's ready for use at once! This one is the best tweak I have seen so far.

I definately think its coincidence. Anyway its easy to test, just change the registry back and do a timed test.
I wish i could... I can get the GPRS LED light up again, but the BT LED is dead no matter what I do. Anyway, I did at least 20 tests two days ago (before I changed the LED thing yesterday, because of another thread I started here about long connection times), and it was around 12 seconds every time. Now it's around 6 every time, and I haven't made any other changes to the unit.
For the love of god how do I turn this flashing light off???
The registry hacks dont work well enough, the right green LED still flashes in certain cases

I believe that you are talking about Notifications. Well, that's a LED that works different. It's easy to turn off but it will go on the next time you have any notification event. BTW, I believe that in Sounds and Notifications in settings you can turn off this LED in some events.
I could give you a little program that I did form my internal use so you can check what I'm talking about (Notification LED going ON in any notification event no matter if it has been turned off by any other external program).

There is no place in notifications to turn off the flashing LED. Although I think u are right about it being the problem...
This works in my hx4700, but I don't know if this is what you are asking for.

[Q] Backlight on Capacitive buttons not working.. RUU Available?

I believe i have a problem with the ambient light sensor on my G2 for what ever reason my back-light on the capacitive keys on the bottom of the screen when in a decently lit room keep coming on or off its work fine in a dark setting as it should but when i have both of my g2's side by side in the same room one stays on and the other keeps going on and off. I know this may be and most likely is a hardware issue but i purchased the phone on ebay so t-mobile will not let me exchange and HTC currently does not offer repair for the device yet. I was wondering if an RUU has been released yet and maybe flashing the phone would solve if it a software issue. I have factory reset the phone multiple times but it does not remedy the problem. does any one have any suggestions?
Is the RUU released yet?
Any one? ?

This is linked to the keyboard backlight, they both go on and off at the same time. I'm getting the same problem too on my DZ, the light sensor doesn't seem to be setup properly because it keeps going off and back on again (even if auto brightness is set to off).

Touch Pro2 (Vodafone UK) - blank screen

I have a Touch Pro2 Vodafone, but unlocked, and flashed with custom 6.5 ROM and it continually has the problem of the screen going blank and not coming to life.
I have tried Energy Rhodium 29022 and another ROM but both have the problem.
I guess it might be a hardware fault, but not sure really.
Any suggestions for fixing?
task29?
Does it "always" go to the blank screen, or is it intermittent?
Also, when you say going blank and not coming back to life - does this mean when the phone is rebooting? When it's off and being turned on? What are you doing that induces this behavior? Has the phone always done this? Have you tried the stock ROM?
You could also try remapping one of your buttons as a 'Power Management' button using the keyboard configuration to see if your power button is at fault. If all else fails, try flashing the shipped Rom to see if the problem continues. Good Luck!!
Sounds like a failed light sensor. Somewhere there was an app you could install that would display the sensor reading. If it was 0 then you had a bad sensor.

I know of such a thing for Android, but does one exist for WinMo?

I want to say that there was. It wasn't the primary function of the app, but info you could get from it. It has been more than 6mo since I was fooling around with WM on the TP2.
I ran task29 before
Have tried three roms
Problem occurs e.g., today, blank screen, cannot activate, remove battery, try to turn on, get the buzzing sound which means it's turning on but still blank.
Press buttons, oops looks like I'm calling someone.
Phone still blank. Then get incoming call - it wakes up.
This happens regularly, blank and cannot wake up.
Usually charging it wakes it up.
Flash back to stock, if it's still occurring there it's probably a hardware issue. As was stated earlier, the proxy sensor is suspect for sure.

That really sounds like a bad sensor.
And the advantage to that is, if it is a bad sensor, you could always perform some surgery on your device and install a new screen & digitiser as I did on mine. I had a problem with a slightly rattly earpiece afterwards but I think it was something I did. Handily I was able to purchase a pre-built screen and digitiser as a single unit complete with ribbon cables, I just had to swap it out and reattach the various ribbon cables. Proximity sensor and LDR are all in the one unit above the screen... Which is quite useful as they're all tiny surface mounted components
If you don't want to invest money, and like android I think that FRX07.1 does not use the sensor. That build would let you use the phone as is.

Installed HU, messed with the elements inside settings now button lights don't work

So I'm a newbie here so sorry if I do something wrong. I just installed my headunit and when I turned it on, I thought the lights could've been a little brighter so I saw the elements setting and messed with it to get a brighter color. After I did that, my button lights no longer work but the rest of my illumination lights in my car work except the headunit. Does anyone know what the problem could be?
Got exactly the same problem. Would be very appreciate if someone could give an advice.
I know on my unit the button lights won't work unless my interior lights are set to the highest setting.

Also heard about that, but didn't work for me. :crying:
You could go into the factory settings menu and select RGB LED or keylight and see how if that changes anything.

Already tried that too. Actually, I tried almost everything that is known except modifications of hardware. I just was wondering if there are some other tricks to fix it.

Did you take out the Head Unit?
You may have dislodged the illumination cable on the unit. This happened to me.
I had no illumination, searched forums then found out that I needed to connect ACC to the "orange wire" (Xtrons head unit) then all the lights were illuminated.

Screen too dim, backlight(Maybe) not working.

Hi all. I have a rather weird issue. After droping(oops) my phone, I ordered a new lcd. I shelved the phone as it was unusable until the screen arrived. When the screen arrived, I saw that the battery was dead. I charged it and changed the lcd. That's for the backstory. Fast forward to now. When I open the phone, the screen lights up at full brightness as one would expect at the android one logo. It stays there at full brightness for about 8secs But as soon as it starts loading android the screen dims to absolute dark. In the beginning I thought the phone was closing, you can't see anything... Unless you close the lights.
But even in absolutely dark room, the screen is still very dim, barely discernible. The phone works absolutely fine otherwise, touch camera sound etc. I backtracked the process and put it's original screen on, but it does the same.
I tried disabling auto brightness it does nothing. In fact, changing brightness from the slider does absolutely nothing whatsoever.
Tried calibrating the sensors from the engineering menu(not sure it was called that, the one you enter when you put numbers on the call menu) they seem to be working, but the brightness doesn't change.
Tried removing the battery for a prolonged amount of time (around 6 hours iirc). Still same.
At this point i'm thinking:
1)Software problem. I will really need to hard reset the whole thing, which i'd rather not, and hope for the best.
2)Bad screen, which doesn't explain why the previous one has the same problem, or why the screen works during the logo.
I hope I was able to give enough info. Any help would be greatly appreciated. Thanks!
Hi, I'm having almost the same issue (display very dim, but for me it is always very dim) and this manifested not after any dropping or screen replacement, I guess I just wrongly inputed a button sequence that configured the mobile in this weird status. It is really annoying as it is almost impossible to unlock sims, basically the phone is unusable, very frustrating....
Hey there, did anyone found a solution for this issue?
Has anyone solved this problem?
Have you found what was causing this?
I’ve the same issue, replaced the lcd on a xiaomi mi a1 and the backlight is present at the logo startup but completely black after that.[br]
On a dark room I can barely see the screen and all it’s working, but adaptive light button is missing, seems like the bootloader is able to use the backlight but not android itself
I have the exact same problem, i really hope someone knows a solution to this. I tried pretty much anything within my capabilities
