Hi, I have replaced the screen of my DHD with this producht Click. But now I have big issues with my phone. My Wifi won't turn on. When I press it to turn it on I get an error and also the bluetooth won't turn on. When I press it, it keeps trying to turn on but nothing happens. My GPS turns on but can't find any signal and the lights on the touch button's dont turn on. Can someone please help me with these problems?

thats a big problem, but most development here on xda is software, not hardware est bet would be to recheck everything is connected completely, when ever a screen breaks, your best bet is to usually just upgrade, hardware is hard to modify.
It's not that I'm 100% sure that the hardware has problems, but it happened after I changed the LCD etc. So it has to be because of that. Can someone tell me which part of the motherboard is the wifi so that I can check it for damages etc. or are there other things that I can do in order to try to fix it?
Thank you in advance.
I thought the WiFi/cellular antennas are somewhere in the upper part of the phone.
Usually it's some kind of wire running along the edges.
I thought GPS was on the led surround Bluetooth was on the battery cover

Hi, I have 3 wires there, 2 black and 1 white, do you know which one it can be and how I can fix or replace it?
Hi, this is the inside of the phone, can someone show me which part the WiFi is?

Can you take some pics???
CU AssiY2K
Of what do you need a picture?
the gsm/3g antenna is in the sdcard/sim-cover
the wifi antenna is in the battery cover
and the gps antenna is in the cover on the side of the camera that includes the lenses for the LED flash
@ niyesuh: I couldn't see the picture you have posted. In this afternoon I was at work and there is the internet connection firewalled. But now I can see it.
Dlog is right.
Are you sure that all connectors do have right connection? The battery flap has to be mounted if you want to test WIFI.

Yes, all the connection's are connected correctly and the battery flap is also mounted well. I think I broke something while replacing the screen, but what could it be?
Also the Wi-Fi MAC-adres isn't available.
Hi, i had the same problem today.
I solved lifting a little the metal contacts under the two plastic covers (wasn't sure about which one was for the wi-fi/bluetooth antenna)...

Is there anyway to boost the wifi on this thing. I have 3 tablets (samsung tab 7, Lenovo Ideapad K1, and this) Samsung and Lenovo keeps connection with my home router but this one it disconnects half the time. Kinda frustrating. I assume this also will kill my battery faster than it already does. Any advice?
EDIT:
So I exchanged my tablet and still the replacement has bad wifi. I figure this had to be hardware related so following the procedure here I decided to take it upon myself to figure it out. If youre not comfortable doing this I suggest just keep returning your unit till you get a good one. Note when you remove the first side bezel there's a black sticker over one of the screws. I was able to remove it easily with an exacto knife being careful not to rip it so I can put it back on later. After removing the 3 sides except for the power button side (not necessary) you remove the back off and you end up with this.

I'm not sure which is the wifi antenna or if they work as a pair but I moved both antenna connectors around (I didnt try to remove it cause this might make the connectors loose) and moved the black antenna right on top the camera. Reference all the red arrows. I left the tablet on so I was able to tell if it was making a difference. Eventually got it to get 2 bars just like on my Lenovo Ideapad! Possibly one of the micro coax connetors was not making good contact. These are the same RF connectors on RC receivers so they are a little more susceptible in losing contact specially if they're too lose. So just move them side to side and dont remove or lift them off.
Prior to this I was alternating between no bar and 1. This time it consistently stayed at 2 bars regardless how I moved or where I moved in my room (our router is in another room upstairs). Carefully put the tablet back together and now my connection is stable 2 bars. Finally!
So it does seem like there's some QA issue with these tablets. There's a huge thread in the acertabletforum about this issue and some say to change your connection from DHCP to static but that doesnt make logic sense to me. Some have been able to exhange theirs gotten good replacements.
Anyhow if you have any question, let me know.
I was actually thinking that wifi going out when it's turned off might be on purpose to prolong the crappy battery life.

Not when its turned off. Theres a setting for that to disable wifi when you turn screen off. But thats not what I'm talking about. My wifi disconnects as I'm surfing or downloading from market or a file.
hmm, does it look like it has a weak signal strength or are you sitting at a good connection and it drops all of the sudden?
If it isn't a weak connection, I assume the device is just having a problem with your router settings. Maybe call support to see if they can give you information, but I haven't heard of this issue. What about open networks at coffee shops or the like? Do you have the same issues?
This is my third tablet and this tablet has the best WiFi that I have seen so far, so I don't think it is a problem with the signal strength.
Maybe I have a bad unit but I went to Bestbuy today and the a100 could not connect to their bestbuy router. It says "not in range". All the other ones (galaxys, xooms, acer, asus, HTC flyer all were connected to bestbuy wifi. HTC and samsung were the better ones at full bars. Acer had 2 and asus had 3. I don't recall what the xooms were. But man what a disappointment. The only thing good was that the a100 was the cheapest at $249. They must've brought the price down again.

Are you on 3.2.1 already? Maybe thats the ticket. I'm still on 3.2 and it says I'm up to date when I try to check for new version. If you are on 3.2.1 how did you get it?

I may be wrong but I think it's light (or proximity) sensor cable.

The lights are working properly. Maybe you are right about the proximity sensor, I am gonna try that right now. Thanks!
edit: The proximity sensor is working as well. Any other ideas?
I think he means the ambient light sensor. Is the auto-brightness working properly? Or maybe the notification LED.

Both functions are working properly. The weird thing is that I use my phone the same way as before and everything works great, that is the reason I don't know what the function of that cable is.
Hello,
in a video about Desire HD disassembly, they call that cable "Bluetooth coaxial cable". You may check for proper Bluetooth connection and reception.
If you want to verify, try youtube search for "HTC Desire HD Disassembly Video", it's around 4:35 where they disconnect it.

Antenna for radio/mobile ?

I guess that is the problem. I get strange noises when I try to listen to the radio. But i'm not sure because I use a ICS ROM. Thanks!
Personally, I don't think that it's the radio antenna.
I heard that the phone does not have a radio antenna.
I heard that the head phone cables are used as UHF radio antenna.
I also don't think that it's some kind of power cables as the connector is a coaxial connector, so it's definitely some kind of radio signal cable.
Bluetooth sounds reasonable...
Did you already check the signal strength of your Bluetooth connection? Or maybe the signal strength of your wifi connection?

Thanks for you effort. Bluetooth and Wifi are working very well, I don't experience any problems with that. I don't experience any problems at all, I'm only curious what the function of that cable is because everything is working properly without that cable.
coaxial cable
one cable is for the gps and the other is the blutooth, white and black, it tells you in the video by htc, its not the gps cable as mine is broken and it stopped the gps working altogether
Bluetooth coaxial cable according te all videos i can find on the subject.
It is the cable for the bluetooth antenna, mayby your bluetooth have reduced range?
That video is made by or for the HTC company itself and I doubt they would call it by the wrong name-tho stranger things have happened. I believe bluetooth is what it is, and as someone suggested-It may purely be the strength of signal that gets afftected not the function itself,
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...

I just couldn't stand to do that.
Still, the official purpose is one too long pin (marked with red on last photo), which deforming the back housing cover.
Has got to cut it down a bit.

Just to make sure; so you dont separate the white back cover between the from the bronze and the cover but between the bronze rim and the glass front?
OP, did you cut the long pin? Also, was it easy to pull off the screen from the back cover? I may try this because there seems to be a slight bump coming up from my T700.
It looks to me like the usb port is a separate module which is good news. In the past i've had to repair these by desoldering and replacing, which is not any easy task due to their minute size.
Hi, I've got some questions. Not precisely about the deformation, though. Hope its not an issue.
I've got this issue. Battery draining even while the tablet has been turned off (completely off - turned off via the software button that comes up via long press on the power button).
Amongst other things, I suspect that the power drain has something to do with the antenna's on the back cover. Anyone know what those antennas are for? They say stuff like LTE and WiFi however, I've taken off the back cover and its still connecting to mobile data and wifi etc. So these may be extra antenna's etc.
bluetooth and gps need antennas as well though some can share.

Hi the little white cord above the camera is missing from my tab. What is it?
So my sd slot was messed up so I took it to get repaired, the guy fixed it but now wifi and bluetooth don't work properly. It only works when I'm extremely close to the router/bluetooth device and even an inch or two away and it disconnects. Is there any way I can fix this myself, or anywhere I can take it to to get fixed? I've tried but the guy I took it to had no idea how to fix it. I read knocking near the rear camera fixed it for some people, but I've tried that and it doesn't seem to work, and since I'm assuming the guy physically broke it somehow I doubt it's a software issue. Thanks.
Did he connect everything properly?. The WiFi and Bluetooth, I believe, are one in the same chip, or at least on the same board.
It could be a case of replacing the board but if it works close to the router then I'd say that maybe there's a problem with the antenna, if there is one. If there isn't I'd blame the cable supplying the power to that board..
The m9 is notoriously difficult to work on and it is VERY likely the repair was accidentally botched. The new problem is asking someone else to investigate and repair it properly. Don't tell the new guy it was buggered by someone else or he probably won't touch it.
