Hi,
A few weeks ago I had a broken LCD on my Desire. I've fixed that myself, it was pretty easy. First all thing looks great and I was very happy that the did the fix myself.
After a few hours I start calling people there I noticed a problem thats vey annoying. It looks the sensor for ending a phonecall is broken. Before when I ended a phonecall, the screen goes on again. Now the screen stays black. There arfe two situations.
1) when I want to end a call (for example when the called people are not at home) I can push the power button a few times, then the screen goes on and I can hang up. This is frustrating, but it works.
2) When the other side hangs the call earlier than me, I've a problem. The only way to get the screen on is to remove battery.
especially the second example makes the phone unusable. Hopefully any of you knows a solution of maybe what type of hardware is broken.
I've flashed two different ROM to the phone, in both the problem is there.
After a lot of Google searching I've found that the problems are from a broken proximity sensor.
I found a person who said that a vacuum cleaner on top of the screen will do the trick, not for me.
Can anyone describe how this sensor looks like? I've replaced my LCD, so I think done something wrong with assembling the phone again.
Today I've disabmled the phone to look at the proximity sensor. I can't find anything wrong.
I've look at the tips in this forum:

Hello,
I found root cause of this problem;-)
Proximity sensor have two part- one is infra red emiter (TX), and another is IR sensor (RX). Inside arround sensor you will see glossy metal parts and little gap in plastic bariere between this two parts. Solution is: use dark isolating tape and cover glossy metal parts and fill gap between plastic and metal. After this modification all will works fine!
(Because glossy metal parts inside happends multi reflection and sensor is blinded with near IR emitter)
balki (croatia)
That comment of balki looks a lot of people saying that this is the trick, but I didn't understand what he's meaning. Can anyone help me? For example, the sensor looks like this part:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I've cleaned the sensor and glass before the sensor, so dust isn't the problem anymore.
I've found the problem, fixed by the solution of Balki.
On this picture you can see what Balki means:

That rubber part is mostly missing after replacing a lcd or digitizer. You can order that part at ebay, of fix it like Balki said with black tape. The holder (or tape) are there to be sure that the two parts of the sensor may not see each other.
Good find, GAEvakYD. Thanks for the details.

The siding on the left portion of my phone is not flush with the keyboard portion. I can always feel the "lip" or whatever you want to call it. This is a Tmobile TP2
Its annoying that phone isn't fully flush with itself.
Does any one else experience this?

I'm using a Telus TP2, but I can say that I haven't had any issues in regards to this.
yeaaa i have the same problem.
its as if the phone is crooked towards the left on the bottom half. if you slide your fingers together down the sides you feel the phone screen move in right as if it was not aligned correctly
Same problem here MPD suggested I go direct to HTC regarding this, as it was outside the 1 week direct swap window.
Apparently HTC have a 72 hour turnaround in the UK
Same issue here with both mine and my fiance's T-Mobile TP2, so I just assumed that's how they were. :\
glad to know i'm not alone & not just on Tmobile
wow i never even noticed this. Just another problem to add to the list.....how wonderful. I just posted my review of this phone before reading this thread and looking at my phone.
Aligning the two sections
I've found the same problem. Placing a small ruber patch at the end of the rail slots in the screen piece left my phone completely aligned.
Instructions:
Get some adhesive rubber piece that's about as thick as the misalignment in your phone. In my case, it was just one mm, and I found such a rubber piece as the filling between optional rubber "feet" that came with one router I had. I guess the chances of you having the same thing are dim, but the point is that this type of material shouldn't be difficult to find, just look around. Any hard rubber film with one adhesive side and the appropriate thickness should do.
Cut two pieces that are 1mmx1mm, and place them (tweezers will help in getting this done) right at the edge of the rails at the bottom of the screen piece. When viewed from below this should be at the left side of the bottom of the screen, right at the edge of the screen piece.
Close the keyboard to get the pieces stuck in place.
My phone is flush now.
cool I'll have to try that
Thanks for the tip, herbys. I had to do something similar on my Nokia N95 to fix the wobble in the slider.
I've had three T-Mobile TP2s so far and the lip is most noticeable on my third and current unit. My co-worker has one and his sits perfectly flush. I imagine it's just a small fluke on the assembly line, but I wonder how widespread the issue really is.
Hello guys. I'm currently trying to fix a friends HOX that fell and now the screen doesn't always display image although we can see it always lighting up (it turns on but stays black) .
If I press hardly the HOX's area in red while turning it ON, it works fine. I'm assuming this could be some broken welding points but would like your opinion.

I'm thinking of heating the area with a heat gun, but I'm afraid I'll kill the rest of the phone... what do you think?
Also, after disassembling the phone, the vibration stopped working and I've checked every flat cable and every connector I could find...no ideas to fix this one since it was working before I cracked the phone open.
Any comments are greatly appreciated.
Tks

Possibly a chip has become partly detached from the solder ball grid array due to the shock of the fall. You will not be able to repair this by heating, even if you could reach the melting point of the solder.
The manufacturer would repair by replacing the circuit board and the existing one would be considered unserviceable.

So in resume, my friend has a HOX for spare parts... damn...
Couldn't you pack the inside of the housing at the point where you need to apply pressure? Using a piece of card or something. Hardly ideal but would make it functional again
That has been my first attempt, and it's better but still, not enough.
I'm going to disassemble it for the tenth time in a final effort...
tks for the tip though!
So, I've just realized the back metal plate comes out nicely and I think I've found the problem for the GPU issue... that small component on the red area has a broken piece lol (WTF!)
I have applied pressure directly on top of it and I think it will be usable like this, but it now needs a bit of daily use to check if I'm right or wrong.
Can anyone identify what component type is that?
Also, unfortunately (and I don't have a clue how this has happened), the vibration stopped working after opening the phone on the first time, any one has any ideas of what to look for? I don't see any flex cable cut or any other damaged parts...
Tks guys.
Problem solved, some back pressure on the broken piece and the hox is good to go.
The only thing still not working is the vibration...

Hi guys,
Two weeks ago, I had broken my screen. I bought used screen and I go to the mobile service to replece broken screen. It's works two hours, after this time I started have problems with screen. When I wake up phone, it's works OK by 10-15 sec, after that time, on screen apears white or coloured stripes . Here is the photo which shows problem:

Anyone have same problem or have any idea how I can solve it?
Hi,
I think it definitely bad connection between screen and motherboard:
badly installed (I mean someone who installed touched touchscreen connecting pins with fingers) ... or ... oxide on touchscreen connecting pins ... or ... possible water damaged used screen (seen one analog case).
It's any possibility to repair connection if screen it's OK?
Anyone know smoething about two types screens in G3?
It's similiar to that problem :https://www.youtube.com/watch?v=DI64Bcf8OiE
which it's solved by: http://forum.xda-developers.com/showpost.php?p=52414185&postcount=122
Maybe changing kernel/soft will solve problem?
Hi,
Actually about software side I dont believe. I hope this used one was exactly same, what you had before. If I remember right, then LG didnt made different screens for G3 different models.
I remember that G2 had many problems with white lines after drop or screen change. Fix was easy, to add metal tape at display connector to antenna. To understand better about what ia talk you must read this link.
Anyway, I sill think your problem is hardware problem if on start it works normally.

In g3 it's any chance to solve that with metal tape? In g3 motherboard it's different so maybe tape can't help. Tomorrow I'll try one more time check lcd plug.
Hey guys. I bought my Z5P on dec 23. It had a broken screen, i replaced the screen early in January and everything was great.
Then in early February the screen would get vertical lines at times, suddenly appearing then randomly disappear after 10 seconds all the way up to 8 hours later. The screen would randomly become quite warm/hot a couple of millimeters above the on screen buttons, aswell as heat up the entire phone randomly while in standby for some reason.
On Feb. 10 the lines came to stay, they are now constantly there in darker images as well as constantly sometimes in all scenarios. The 3.5mm port is also buggy and don't work if i move (I know about the software issue, this is hardware related).
So, i'm faced with exchanging the screen again for 60-70$ or change screen and frame in one for 90$ as well as the 3.5mm. Should i just throw in a new screen or will the problems likely reappear?
I did the previous swap myself, and cant find anything wrong with the install. The screen may sit a tad bit deeper in the frame now, the plastic edges rise above the screen on both sides. Screen appears to be OEM, same quality as original in all aspects until it failed. The phone has obviously been tampered with before i bought it, its missing 1 plastic cover over the charging port so i propped that up with a plastic piece as well.
Anyone with any experience with these kinds of problems on this or other Sony phones would be greatly appreciated!
Thanks!
For some reason i clicked the wrong button on log in and posted with my google user.
Here is a image showing my problem on a different phone.

since you bought it with broken screen, the scientific question for you to be asked back then was
1. how did it got broken? dropped from height ? heavy object dropped on it.... in either case....
2. what else may have had got damaged inside?
My sister had SAMSUNG s4 and she dropped it , it hit on the floor and lines/bar started appearing after a while! later the screen went blank... we replaced the screen and it worked only few hours and went blank again! ,,, finally the technician told us that processor or graphic chip may also got damaged or affected so replacing chip is not possible unless you change the mother board! (which will cost $400 with labour charges )
long story short! we gave up on that phone! when the market is saturated with variety of good hardware on competitive prices...
Hello. Some weeks ago I sent my Nexus 5X to the technical assistance with the problem I described here https://forum.xda-developers.com/nexus-5x/help/brick-apparently-reason-t3680715. Now they told me that they won't repair it under warranty because they found traces of liquid/oxide inside it, so they are sending it back to me unfixed. Now I find this odd because the only encounters it has made with water were in the form of small quantities dropped on the screen (the amount you can drop by moving a glass in the air too quickly) which I dried immediately and the symptoms seemed to point to a bad contact. Anyway the repair center provided an image in which seems that actually some liquid has made it inside the case, but I can't recognize which part of the phone it is. Here's the image:

}
So the questions are: which is the part in the photo? Do you have an idea about how could have a liquid made it inside the phone (I think that is unlikely that it was by dropping something on the screen)? Do you think that the problem I experienced is compatible with a water-induced short circuit or any other damage by liquid?
Thanks in advance for your answers and explanations
I actually thought that was a picture of the shipping box before I read your post. I took mine apart to where I could pull the motherboard off, and there definitely wasn't blue tape holding something down. The only thing I can think of is that is maybe the back of the screen. Which would be after pulling the metal frame off.
Check out these pictures. If you go all the way toward the end steps, you can see you get all the way until there is mostly the metal frame inside the plastic and stuck to the back of the display without seeing anything that looks like your picture.
Their picture honestly seems to be an entirely different phone. But of course they may have changed assembly and parts at some point. I would take it apart when you get it back, take pictures and if nothing looks like the picture they sent, see if you can appeal or whatever. Maybe you can just point to the 3rd party teardowns and ask them to point out where they claim the picture is from.

I think it's under the battery, the blue part looks like the battery adhesive but it's normally black,
It was was to get behind there it would of had to enter via the simcard
