Defective Unit? Pls advise

Hi Guys!
My TyTn is acting strangely. In use, the display is first pixelating, getting lines (noise pixels as well), and then fading to completely white. When so it doesn't responde to anything anymore. So a soft reset is needed.....
Also the ringtone when called, is 'out of tune', like a old record player when you push your finger on the record.. LOL
Before I send it back to have it fixed by HTC, do you guys have any idea whats wrong, and maybe even a tip to help me fix this myself?
Tried numerous soft resets, hard reset, and a reinstall of the original WM6 rom (in Dutch).
Did not install any new programs lately, or did change anything on the unit...
Don't want to miss my TyTn... so hate to send it away... as many of you I am hooked badly to my beloved digital companion

It acts like hardware incompatible.
How about flashing with WM6 English version.
I don't think it is software problem.

I agree, not likely to be software. It did not get dropped or take a knock did it?
The two issues of pixelation/white screen may, if you are lucky, just be a connector thats loose. The sound I think is unrelated but again sounds like a poor connection at the white rear speaker connector block - not uncommon.
Both of the above could be caused by a sharp knock. There have also been cases of poor battery connections causing problems.
If you have a warranty use it. If not you can follow the dismantling guides or service manual to dismantle - check connections and re-assemble. Be prepared though, that sending it in might still be required!!

Will send it in
Hi Guys, Thanks fr your replies.
I will take the unit back to the store today.
I am not aware that I bumped it, or neither it has dropped. May be a connection that was allready quite loose to begin with. Lets see what HTC and the store will tell me
Strange thing is, that without my sim in it, and not using it, it stays normal... Have put it aside, and used a very old phone instead, and it is still normal..

Mmmm... that's important information and changes things a bit. Could be a sim card contact or something about the sim. Anyway it tends to suggest that other thoughts about hardware issues may not be correct!
Hope you find the answer at the store.

Difficult to connect to GPRS and Wifi unstable after replacing LCD display

I broke the original LCD display and the touch screen, then my Artemis has been in the desk, turned off, for a month... Then I bought a new display with touch screen on ebay and have installed it successfully. Somehow, after the replacement, the GPRS is difficult to connect, most times it is not able to connect. I've discovered also that Wifi is not working very well, it drops from time to time...
I've already upgraded the radio rom for the latest one, 3.34.90, to try to solve the problem and it looks like it did not help.
The only thing that I can suspect of being the cause of this, is the type of the display, is related to the hole in back of the display, which could mean a different type of display. The original one had a "L" shaped hole and the new one has a retangular shaped hole.
The new one is like this below:
The old one was like this below:
Any thoughts?

maybe when you disassembly the phone the contacts of wifi antenna and gsm antenna who is on the back cover didnt make good connection try to disassembly again and pull little the contacts to be sure that make good connection.

Thanks for the reply, but it seems it was coincidence.
Recently, a new operator started their services on my region and that seems to be the cause for the unstable GPRS. Regarding the Wifi signal, it was bad at that day, but now it is ok. Maybe it was really a matter of bad contacts on the antenna, and somehow it is cured now...
Originally I suspected of the type of display because there was a merchant on Ebay that stated these types were different, but sounds like bull****.
Thanks anyway.

Bluetooth and Wifi won't work!!!!!

Hello;
It's been like a month that I have this problem, my bluetooth won't connect and neither is my wifi. The wifi sometimes connect with like one bar, the signal strength is awful and you have to be like 1 feet away of the router because if you move farther it disappears. I have tried to boost this in the settings by better performance but it doesn't make a difference.
In the other hand the bluetooth is not working at all, I tried to connect to my laptop and is like there's no bluetooth device in the area, tried it with my headset and get the same thing.
It's really frustrating cause this two features are very important for my daily use of this phone, so if someone now what to do please let me now.
Appreciate it!

Same here!
I have the exact same problem and apparently by the lack of posts anywhere on the internet nobody has an answer.

im having EXACTLY the same issue. im gonna open it up and see whats up.

The answer might lie within?
Try this link? What you're looking for might be somewhere in amongst these threads? http://forum.xda-developers.com/search.php?searchid=48353718&pp=25:confused:

can you repost that link? its saying search is down..
edit: working now.

???
I get a "Sorry - no matches. Please try some different terms." message.
???

nothing worth noting on the link. im gonna send mine back to htc..

I'm hoping someone will get to the bottom of this as i miss my wifi.
All was working fine on my phone until I had to take my phone apart because the plastic led shield had come lose and was touching the vibration device causing a strange noise.
So i managed to get the phone apart and push the led plastic cover back into place, i didn't touch anything else. I put the phone back together and all worked fine until i tried the wifi. Nothing, it turns on but stays as scanning and never finds anything even if its right next to the router.
I was advised in another thread that one of the cables might have come loose as i took the phone apart so i opened it up again but couldnt see anything wrong.
I'm just wondering if its a software issue somehow. As i never touched any part of the board, or antenna etc whilst it was apart and like i've said i couldnt see anything out of place or loose. Whether a hard reset will solve the issue i dont know and its a pain to do really.
I haven't tried bluetooth, but considering it looks to work off the same antenna that too might have broken.

maybe solved
find bttrayce.exe or bttrayce.lnk in windows folder
run it and check them
copy lnk file to startup folder
restart
this is for wi-fi too .

I've run bttrayce.exe and the ink file is in the start up folder.
This hasn't made any differance.

enable wifi n mode using registry editor like total commander or resco, go to:
HKLM/Comm/BCMSDDHD1/Parms/11nModeDisable = Change from 1 to 0
or, install bsb tweaks and enable wifi n mode.....
or, the best answer is to flash a new radio-improves bluetooth, data, wifi and call signal

did you hard reset and the problem persists? then it is a hardware issue, send it to htc.

so wait, you take the phone apart, put it back together, then it doesn't work, yet it isn't your fault? I hope you didn't screw up the void sticker covering the one screw when you did this, because you obviously damaged the the wifi cable in some way.

Obviously i'm aware that what ever has happened is my fault, my point was that if i'd taken it apart and knew i'd done something that might have damaged the board etc then that's fine I would be able to pinpoint what it was, but as i didnt do anything really especially to the main phone just the back case it's just a little odd.
Void sticker is fine.

seems like an antenna problem, there is a cable on the side of the phone with the volume rockers, there will be a cable going to the top board to the bottom board this cable attaches and can be removed. try to remove then reattach the cable
http://www.youtube.com/watch?v=cL-jnUKufC4&feature=player_embedded
the cable is on 2:38 of this video.

Right I took my phone apart again this morning to double check everything. I noticed the cable attached at the bottom as mentioned in previous post. It lifted off a bit too easily, so I positioned it correctly and pushed it back down, my WiFi now works. So that was my issue.
So my advice would be if both your Bluetooth and WiFi do not work, it is more than likely the cable is lose. (more likely if your phone has been a part obviously)
Thanks for everyone's help and advice on here.

I had the same problem with my GPS. I took the phone apart and found that the GPS unit was connected to an amplifer via two gold prongs. The connection was not flush, so I stretched the prongs abit (not too much) to improve the connection and put the phone back together. The problem was now fixed.
From memory I think the bluetooth and wifi worked on the same principle, and I think the amplifier states what its function is.
Hope this maybe some help.

[Q] Water damage

A few months back my Legend went through a cycle in the washing machine. Afterwards I did all the recommended things (take everything apart, leave it in the sun for a day or two, keep it in a jar of water absorbent silica in the evening). Anyway, after three or four days of that, I put it back together again and my battery was dead. Tested it with someone else's battery, and everything worked perfectly, I even made a call with it.
I then waited about 3 months for a new battery (it got stuck at customs) which I finally go this week. Thing is, I now have 0 connectivity with the phone no matter what I do. I always have 0 bars, I can't connect to wireless networks (even though I pick them up perfectly), and I can't get the GPS to turn on at all. Everything else works fine (including the FM radio), but there's no connectivity.
I was hoping it might be a software issue of some strange sort, since the wireless picks up well but just says "connecting--disconnected" when I try to connect. A hard reset did nothing to the phone though.
Is there anything else for me to try? I'm running pretty thin on ideas at the moment. Would replacing the back cover fix any of the connectivity issues? Also, is it still possible for it to be a software problem, and should I maybe try to install a custom rom on it?
Any advice at the moment would be much appreciated. Thanks!
EDIT: I just realised that I had made things worse with my reset. Now I have no file browser with which to sideload apps and no internet connectivity. EDIT2: Managed to fix the file manager problem with ADB. Now just the actual problem again

The GSM antenna is in the bottom part that covers the battery compartment - I'd say you have some oxide on those two contacts.
Take a small screwdriver (or a needle) and gently scrub those pins on your phone.
As for the two on the cover, you'll notice those two parts come apart, so I'd take the inner part and gently brush the two contacts with a piece of cloth and a toothpaste - it's a good thing to gently brush something.
If that fails and you're sure you plugged all inside as it was...it could be another problem...
You may also try bending the two contact in the phone out - these act like a spring, but be gentle about it
P.S.: Is your Legend at least clean now?
EDIT: Now that I think about it, you can try the phone with piece of wire:
cut a wire of : speed of light/frequency in Hz and connect it to the two pins inside the phone
For USA:
299 792 458 m/s divided 1 900 000 000 Hz = 0,15778 m

Thanks Dr.Romca.
I'm trying the clearning out for now. when you say the battery cover comes apart, are you talking about the piece of plastic inside the rubber? There seems to be an additional piece of plastic inside the rubber which might come loose, but I'm not quite sure how to pry it out without breaking it. Any tips on how to do this?
I'll give the piece of wire a skip until the very end

It's not glued or anything, just push the rubber part in the middle and try to click it out...

Ahh ok, I wasn't sure what to expect on the other side. Didn't want to jam a screwdriver in between the plastic and rubber and hurt some electronic component. Managed to get it loose though, and gave it a thorough but gentle rub down.
EDIT: Nope, still no service on it. I still find it strange that it doesn't want to connect to the GPS or the wireless either. As far as I know, those shouldn't be affected by an antenna issue right?

That's strange... WiFi and GPS antenna is in the other rubber part....
It seems there might be something wrong with the PCB...
I'm at a loss here...

Damn I have connectivity issues here...
The strange thing is it worked once after the washing...
If you have the courage for it, you can also try this:
Take the phone apart, I mean really apart, if you can unmount the display/touchscreen. Then take the PCB - mainboard, try to put a sticker over a microphone and the repro, then take a toothbrust and a detergent and brush the PCB - make sure you clean all, there will probably be some metal plates that look they can be unmounted, so try to unmount them and clean beneath them.
After this take the PCB and put it in the hot-air oven (if you have one - NOT a Microwave! ) 40 - 50 °C for like an hour should do the trick...
You can also use alcohol to clean the PCB, but since it was water that caused this, I'm gonna presume you'll have more luck dissolving with water again...
Anyway, that's what I'd do, but I'm and engineer, so if you're not sure, just take the phone to service

Hello,
The WiFi and gsm signal are at seperate places on your phone, so you either got a major problem with the hardware, or the ROM just went nuts. I suggest you flash a new ROM before you take the phone apart, cause it might get damaged irriversably..
Goodluck, keep us updated!

Thanks for the continuing advice. You're right about the engineer thing though; since I'm not an engineer I'll leave taking the phone apart until the very end.
I've never flashed a ROM before, but I'm sure I'll be able to figure that out. What initially made me think that the ROM might have gone crazy is the fact that the wireless actually picks up networks. The further I get from a network, the worse the signal, and the closer I get the better, so the wireless signal is working properly. It just seems to have a problem connecting, which seems like a software issue rather than a hardware issue.
If that fails, I'll send it to HTC and see if they can do a repair for me. I already sent it to them for a check-up and a new battery directly after I had it dried out. I included explicit instructions that it got water damaged, that I was not looking for a warranty repair, and I would just like them to make sure everything is working and bill me for the repairs and a battery. Two weeks later I get the phone back with a note saying that they noticed some water damage, and they don't do warranty repairs on water damaged phones Anyway, I'll try them again.
If HTC fail to do anything again, I'll try my luck with a full teardown. Still, ROM flash first.
EDIT: Ok, so I followed this (http://forum.xda-developers.com/showthread.php?t=894465) post up until the end of downgrading your rom, and the problems are exactly the same. From my understanding, this would have installed a clean rom onto the phone, so any software issues should have been cleared up. I'll still try and install a custom ROM, just because I've always wanted to and just maybe something will work, but the software problem seems an unlikely explanation now.

This is getting very strange now. Using my newfound "Wi-Fi" Hotspot powers, I can actually create a Wi-Fi hotspot that my computer successfully connects to. Once again, if the hardware was broken I don't see how this could work. I still can't connect from my phone to any Wi-Fi network though.
As I mention (for a completely unrelated reason) earlier, I sent the phone in to HTC. This might be a very dumb question, but is it at all possible that the ROM on my phone works at a different wavelength/frequency than what is used by carriers in South Africa (where I'm from)? I'm thinking maybe HTC did a stock reset or something which changed it, because I never tested my phone after getting it back from them. That would also explain why my phone doesn't have reception with the current ROM. Just note that I have no idea how these things work, it's a complete shot in the dark
EDIT: My GPS also works now, or at least the gps indicator flashes when it should. Since I don't have any kind of internet access, I have no way of knowing if the GPS works, but in the past it never flashed.
I'm currently thinking of using my computer's wireless to connect to my phone, and then bridging that connection with my UTP connection to connect to the internet. I have no idea if this will work or what exactly if it will get me closer to a real solution, but at least having internet access on my phone will make things a bit easier. Will let you know how it goes.

So have you succesfully flashed a different ROM?I'm not sure what type of rom should you have but WWE by it's definition should work...So if you have rooted, try any WWE ROM...

I first downgraded it to 1.31, and now it's on BlaYo's B0.2.

can you check what radio you are using?
You may want to update it!
It's in settings / about phone / software / baseband version
My is 47.51.32.17U7.13.35.05
Not sure if there's a special version for SA, but here is a radio update only:
http://forum.xda-developers.com/showthread.php?t=706435

Sorry for the late reply. Real life caught up for a day or two.
My baseband version was 47.26.35.04u_7.05.35.26L. I updated it with the radio update you posted, and it's still not working. As far as I know, South Africa can use any American phone except those on Sprint, if that helps at all.
Also, I was away from home for the last week, and now that I'm back home my phone connects perfectly to the wi-fi here. I am certain that I did not make any mistake in connecting to the other networks I tried, as I tested the settings on multiple computers and entered the passwords multiple times, but the wi-fi seems to have been a red herring. So the only problem left now is normal phone connectivity.

I'm sorry to hear that...I'm not sure what the L means at the end...but about the wifi thing, it has been mentioned here that different locations use different WiFi channels...so at this point it's almost sure you have a driver/settings mismatch somewhere...
but I don't know much about that...sorry..

[Q] Mytouch 4g wifi not functional after LCD replacement

I just recently replaced a malfunctioning LCD and shattered digitizer for my Glacier. Before I did that, the WIFI worked just fine. No problems at all. But now, the WIFI will turn on, but won't pick up any networks at all. All my other phones pick it up just fine, as well as my laptop. I've tried three different ROMs and I have the same issue with all of them. As far as I know, there weren't any cables that connected the WIFI module to the motherboard or anything else when I took it apart and put it back together. It's just a little piece that snaps into place, right? I'm not sure what's going on with this...

Seriously? Nothing? Every time I post on here, I get ZERO response... What gives? I see everyone else's problems being solved but not mine...

Sorry, there's no help to give. Don't act like you're entitled to something. I hate people like that. If you didn't touch the WiFi module through the screen and tried different roms then it went bonkers and its toast. TF are we supposed to do about that

If you're gonna post on here just to be a douche, you might as well not post at all. It's doing nobody any good.

All drama aside, he is right nothing to be done really. I guess you could open it back up again and risk breaking something more important than the wifi. Something may be put back in wrong or may have got ESD damange. Truth is unless you're just using this phone as a toy/dev/learning device and don't care if it breaks it is not worth the risk to open it back up.

Trying to fix my external speaker - I mess up working wi-fi. In addition, the case crack and camera button is not working. Should take it to repair shop. Too late now. It would be too expensive to fix it. You my still be lucky and shop will fix for few bucks. Lesson learn - do not mess with something that you do not understand( for me).

coax cable issue
there's 3 little coax cables - I've been told the white coax is the wifi but the black one fixed it so maybe they are all involved. In the process of getting to the LCD you went through these 3 cables. In most cases you wouldn't have disconnected them but certainly by accident it will happen. I put mine on 3 times before they stayed. There's quite positive click when connected but even then it may come loose while assembling the rest of the phone. I just finished swapping out my mother board and as perfectly as I could reassemble the phone I apparently lost one of the coax connections = no wifi. Went back in and this time the black cable somehow got caught under the camera board instead of on top and connected. Easy to see why this was missed because it looked connected.. well looked like it belonged where it was (wrong)
Anyway that's my wifi fix story - hope it helps someone
