Problems with Screen Backlight - Desire HD General

The back-light on my Desire HD screen randomly goes out, the screen is still on and if you look hard enough you can still see the image on the screen. If I put a little pressure on the screen, usually at the bottom by the HTC logo blow the menu button. it comes back on but often goes right back out if if I don't maintain the pressure.
Anyone know how to fix this? I'm guessing that it's just a little bit of soldering that's loose. I really don't want to get rid of this phone so any help would be great appreciated.

not that terrible
if you use your phone for a longer time you now without looking on it where the hardware keys are located so it is not that bad
just use your phone

What? I'm sorry but that makes no sense (no pin intended). How am I supposed to use the phone when you can't even see the screen?

I only get that when using my phone as a GPS with Google maps. It's frustrating. It also doesn't happen everytime, but it did yesterday.

Yeah it really sucks. I just tried a hard shell case hoping that would put enough pressure on the phone to stop this issue but it didn't work. I guess I've reached on the end of the line with my Desire HD. Sucks 'cause I really was looking forward to running ICS on it.

using google maps its normal that screen dims after some time and then screen turns off & auto locks ........
with no display
to turn on display have to use power button .
how ever not checked it in navigation mode ........

Anybody know of any Desire HD "tear down" guides online? Something to help guide in the taking about of the phone. I want to look inside and see if I can't find the loose connection and fix it.
Edit to add:
Found a pretty decent one on youtube

it just turns off

hi,
I got a XDA mini. The battery cover is actually firmly attached to the phone. But everytime I touch or slightly slide the batterycover the xda turns off. So it became almost unusable (take it out of the pocket - it turns off, trying to call - it turns off)
Now I figured out that there is a tiny switch next to the battery (on the right side). Obviously it became too sensitive. I tried to tape it - it didnt help
Does anybody know how to avoid turning it off when you slide/open the battery cover? (I guess its like one of the hardware-buttons, can you turn them off? Registry?)
Or can anyone provide another solution?
I really need help - the phone is unusable.
tnx for any answer
simple , find a tooth pick that has a sharp point (easy to break toothpick) pok the switch ( lower space between the switch and its base. ) and snap the toothpick to make the switch in on direction ( upward) . you can use small paper and stik into the gap use puller , dont use metal object. it will coz short to your board. and i thnk ders no way program can overwrite it. you cant do programing if your computer is unplugged.
Are you sure there is no software way to disable it? I just thought of somewhat like "Buttonx = poweroff", like the Camera button.
Cause I wonder what happens if the switch breaks off ... Guess you cant turn it back on then.
I dipped into the registry - and there is a button-section, but i dont have a clue what those strings are for.
Well - if there is no other way - then ill try it with the tooth pick
I tried it
it worked for about 4 weeks but now its the same thing - i gues there is sth like a loose contact.

im facing the same problem: yes, it sux. how in the hell HTC had that stupid idea to put a power off button contacting with a cover, and above that, it's a tiny little switch, so prone to become damaged!! GRRRR

proximity sensor speed on Leo?

Just wondering, how fast does the proximity sensor react? Does it turn on also when u move it away from ur ear?
In my HD, its pretty slow, and if i remember correctly i even had to install an aditional cab to make it turn back on.. I remember using an iphone and the second i took it away from my ear, before i had a chance to have the device in eye sight, the screen was on already..
how is this with the leo?
Your HD doesnt have a proximity sensor, it uses a light sensor? I think.
The HD2 one is PERFECT! put the to you ear, screens off instantly, take it away and the screen comes back on.
I would echo the fact that the sensor is perfect on the HD2. In fact, I think it's even a little better than 'instant'. For example, if I switch ears quickly, the screen doesn't turn on (exactly what I want), but if I take the phone away from my ear, by the time I've focused my eyes on the screen, it's on and ready for input. Works like a charm!
I'm not sure I'd say it's perfect. For instance, mine doesn't seem to work in the dark (i.e. in a dark room, outside at night, etc.) which is exactly the time I'd like it to work the most.
good to know that!
on the HD i have to wait a good 1-2 seconds for it to turn on, and its annoying what ur ready to go and input something, but u actually are waiting for the screen to turn on..
closer to the Leo..
My (old!) HD is slow too and I gave up trying to use the screen blanking because it also turned off and stopped me from entering key presses to access menu items in the call systems - even when away from my face.
My HD2 is faultless . Works exactly as designed as far as I can see and I have had many phones. If you are considering the HD2 then I would have no hesitation in recommending it.

im not evaluating, it was just out of curiosity, the only thing stopping me from getting the HD2 since day 1 is my current economical status .. im a phone lover also but its still good to know what its improved since the HD.

G1 Screen problem

Hello, My G1 has just suffered a problem, i was scrolling down a web page and the screen faded out like it had lost power but the backlight was still on, the keys lit up and it still could make the trackball clicking noise when you moved it. I took out the battery and left it for 5 minutes and rebooted my phone and the screen turned on for about 3 seconds and faded out like before but it did boot into android as I heard the notification/startup sound. I think that the screen has burnt out but im not shore so has anybody had this problem before and/or might know how to fix it
Just some more infomation, If the screen dies and I leave it for a few minutes, when I unlock it or slide the screen up, the screen works for a few seconds but then fades. Also the fading looks like the screen lost power or like its losing pixels
From my experience with phone hardware this doesnt look like screen problem, but rather the lamp driver in the motherboard. the only way to narrow down is test the motherboard /screen with another phone.
If this is the case, it might require servicing the backlight driving circuit, which by far requries soldering/desoldering some components in motherboard.

Thanks for the replies, it seems that it has fixed its self as I've been using it for about 5 hours and no problems so far, I'm using it right now to type this, if the problem persists I will try and fix it or just buy a new one

Anyone else seeing touch panel lock message?

I've been using the Sharp Aquos Crystal for a few days now and loving it mostly, however occasionally when I have a particular grip on the phone the touch screen stops working and I get a popup that says something like "The touch panel has been locked due to a lack of response .... Move your hand or thing away from ..." The popup disappears very quickly so I haven't been able to get the full text written down or a picture snapped, but I was wondering if anyone else had noticed this and had figured out what it meant.
when u turn on the brightkeep function,the message will pop up while u try to opreating your phone when it on a flat surface. either turn the function off or hold your phone by your hand when opreating will fix it. I am new here. and i got a softbank 305sh. hope this will be helpful.
I think it is caused by the tiny censor at the right bottom side .
Maybe you turn on "Sweep ON" function? if you turn it off, it won't show up but since this device got a power button on some place, hard to push, so I can't turn it off..
the best way, operate your phone with the left hand
When this happens to me, I point the little sensor up or at a light source for a second and that seems to work every time.
The message:" Touch Panel is locked due to the response of sensor on lower right of screen. Move your hand or thing away". This happens a lot and no matter what I turn on or off doesn't stop it. I send an email to Sharp and their response was that my phone needs to be serviced. I called Boost Mobile and the guy was giving me a hard time so I can either ship it away and hope they don't damage my phone too much or live with it but it happens more times than not and usually when I'm sending a text or email.
Happens a lot on mine as well especially if I wear long sleeve or using it on a blanket.that message just show up whenever the lower right of the phone touch the cloth. hand is not at much as a problem.

this is my second Note 4, and has the same problem, random apps openly randomly

First phone had the camera problem, so I had it replaced, but both phones open apps that are not on the screen whenever I pick up the phone or put it down. I hold the phone on its sides, I do not accidentally touch the screen, I do not touch the buttons on either side, and even if I did, the app that opens will always be an app that is not on the screen I have touched. This is obviously some weird Note 4 problem, since both phones have done it and both phones did not even have the same apps installed, it seems to involve the way I hold the phone; holding it in my hand by the sides and walking around with it will sometimes open an app also, but mostly when I either pick it up or put it down, again fingers not touching anything but the sides of the phone, and not the buttons on the sides of the phone either, the only way I can avoid this is to black the screen with the right side button before I put the phone down or in my bag, as otherwise it will open a random app. I think I have gone on long enough to describe this situation, so does anyone have any ideas??

thanks for the info.
Have you check the Notification Panel to see if you have Touch Sensitivity enabled?
thanks for the reply, no, I didn't enable that on either phone.
Just wanted to share: I've had the same happen to me. On one occasion, my phone uploaded and sent pictures to one of my contact as I was was watching. I immediately suspected something nefarious. When I came across this post, I had to share.
I'd recommend that you remove the screen protector from your device if you use one, and see if that helps.
haha bruce lee roy, and to iceepyon, yes I had a glass screen protector on the first phone, but nothing on this one as I want it to break accidentally so I have to buy something new, but again both phones have the same behaviour with and without any screen protector. Really, nobody has had this problem at all with a Note 4 besides me?
