Weird problem with buttons on screen part.

Hi!
I got a weird problem. Seems like the buttons on the screen part have some problems.
When I press some of the button on Universal screen don't work but instead
the up button keep pressed, not phisically but logical.
It's annoyning because I must reset it to back a normal function.
I opened the screen part I checked and made some pression all over the conecctions, without the
back case worked ok, but when I put the back case on the screen the problem returns.
Please any ideas, solutions.
Thanx again, greeting from Chile

I have the same problem. If I rotate the screen around a bit the buttons work fine, but if the screen is on straight the buttons sometimes just keep on going.
I thought it's a faulty cable between the main body and the screen part, but seeing how it works for you maybe it's a connector problem? I bought a new cable and will see if it helps. Mine has a screen color issue too (screens is blueish).

I tried to identify what the problem is, but I didn't find anything. I tried pressing the conecctor to the buttons parts , I cleaned the pins, pulled the flex cable, and nothing ....sometimes it worked and sometimes not. Whatever I will to exchange or replace with another.

Sounds like a cable break too. I think with mine it went wrong when I turned the screen too far. Somehow the rotation was not blocked anymore and I think it got twisted too tight and the wires in the flex cable were damaged. Wiggling the screen would help sometimes, but the problem deteriorated over time.
I finally received the new flex cable I ordered. I paid 44 GBP (66 EUR) for the flex cable to a company in Hong Kong. I think they are raising the prices of these cables, because I thought I saw them for 30 to 40 euro earlier.
Installing this new flex cable indeed got rid of the problem with the buttons and the problem with the blue color of the screen. Both problems rendered the PDA practically useless and now it's working again.
Unfortunately I somehow managed to break the camera. It says "failed to initialize" when I start the camera software I looked it up and people claim it could be caused by dropping the PDA, but I guess completely taking it apart and putting it back together might cause the problem too
To replace the cable I needed to take the PDA completely apart:

:edit: Wow I checked ebay and the only flex cable seller i could find asks $119 for it. They are really becoming more and more expensive or perhaps I just didn't search properly.
:edit2: The store where I bought it still has some for sale for 39GBP

Getting no signal after a hard fall

Anyone can help me, my TyTN fall from my home stairs and I can't get signal after that.. I checked at the "Device Information" in the setting and it shows no Radio ROM.. so I try to install the radio ROM but im getting error during the installation.. I believe it is the hardware faulty and appreciate if anyone knows what is it and where can i get the replacement of the hardware..
FYI.. my TyTN can still be operated, its just cannot get the signal..
Thanking everyone's help in advance....

i'm not sure if you resolved the issue or not, but i'm selling an AT&T 8525. I'll sell it to you for $300 shipped as long as you live in the usa.

I'm not familiar with the insides of the phone, but there are a few options. 1, open it up and find out what's wrong. There could be a connector or circuit that broke and would only require minimal effort to fix. 2, find out if HTC can repair it for you through non-warrenty repair. 3, buy another phone online(like through ebay) that's only good for parts and use it for repairs.
Of course, if you don't feel up to opening it up, you could always find a friend or repair shop that might be willing to try.

ok one of these days i am going to write a book on how to re-attach antennas as the one in the TyTN is similar to the herm100 i presume
you cant miss it, its a big gold rod that slots into a V clip on the main board, a serious jolt could pop its loose, but it wont take much to pop back in, just be careful when you put the cover back on

Yep, there it is top left

And here it is disconnected.
However, I'm not convinced there is sufficient space available for that pin to disconnect while the casing is in place. My fear is a more destructive M/Board fault.
Mike

he could have shatterd the V clip off the board

It's more likely the golden connector from the picture got disconnected than that a board or chip broken. It would require the CASING to break in order for the board to break.
Open it up, take a chance. It's not so hard, just scary the first time.

We could take bets on what it is! No that wouldn't be fair would it
I agree it's worth opening up to check the connection. Depending on how hard the fall was it could be a variety of things. Don't agree that the motherboard can only crack if the casing breaks though - I've seen many examples of cracked m'boards and hardly a scratch on the case.
The OP seems to have disappeared anyway!
Mike

Thanks for the replies.. i've just been busy lately..
Will try your suggestion later to check the golden connector 'coz i've been opened it up many times already so its not a scary things to do for me...
will report back the results

hey again mates..
I already check on the golden connector and it seems fine.. everything is in contact and no physical crack was found or whatsoever...
I believe my TyTN is having the same problem with the one in this thread because I have similar symptoms like
1/ i can't flash radio back (the process hang in a middle of the flashing progress).
2/ there's no Radio & Protocol version in the "Settings->System->Device Information"
3/ no IMEI in the "Settings->System->Device Information"
Anyway, Is there a way to write the IMEI no. for the TyTN? maybe if there is an IMEI no. in the TyTN then can I flash the radio ROM.. i think.. and its worth trying (if possible) . or maybe its a hardware problem like in the thread above...

same wif my herm100 hard fall and no more signal
think tat is crack in gsm chips,u just look forward on gsm chips to replace ur old 1,then should be fine and work well ^^

Hermes Screen (Digitizer?) broken

Hi everybody,
I have a question regarding the HERMES screen/digitizer with which i have always had problems...
I have been using my O2 XDA Trion for a bit more than a year now and i have always had the screen (dis)alignment issue. As i do not have warranty anymore i decided to check out the source of the problem one week ago, so I did a lot of research (also in this great forum ) and diss/reassembled the Trion without any problems. The problem now is : While I was testing the Trion's touchscreen with the included pencil suddenly the screen behavior changed. I am, as you can see on the two pictures below, not able to get in to the lower right corner of my screen anymore:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
There is no way to get in the lower right corner of the screen, even touching at the very low+right point doesn't work. My questions therefore are:
- Do you think the root cause is a digitizer failure? (The LCD itself still works flawlessly...)
- Do you think buying + installing a new digitzer might fix the issue? Might it also fix the screen alignment problem?
- How "hard" is it to install it? Through my research in this forum i heard that soldering is needed?
Thank you very much for your answers in advance,
Cheers,
Philipp

Looks like a digitizer issue as you can't get any sort of selection to happen in that area but the LCD is not damaged as you said.

That's very probably true. The other thing that can cause wierd effects is anything that may be pressing on the digitizer around the edges underneath the bezel. Unfortunately some Hermes suffer from the digitizer remaining sensitive to touch even under the lip of the casing.
Regardless, I would not be tempted to replace the digitizer only. Although it's theoretically possible, it's not an easy job (LCD and digitizer are stuck together and contacts have to be made, positioning accurate , danger of cracking the LCD etc etc). Despite extra cost I would personally replace LCD/Digitizer as one unit.
One final point is that replacement carries a chance that things will not be perfect after replacement. This is because of various sensitive parts that can be affected when dismantling. eg. the d/pad connector.
Mike

Other way would be to find a "broken" Hermes (make sure its not the same problem or whitescreen) and use the whole slideout screen section. I did this and it worked fine...
Got my spare Hermes off ebay....
Cheers...

Hi guys,
just wanted to give you some information on the results.
I ordered the replacement screen 2 weeks ago here in Germany for about 45Euro (which is quite cheap i think, yeah ).
Everything worked fine so far. I installed the screen as described and it directly worked without problems. I have been using the Trion for more than one week now and the best thing is : Even the screen alignment problem seems to have dissappeared with the new screen, yeeppeh
Btw: I was a little surprised but the "new" replacement screen had the same date of manufacture on it as my "old" screen (which is in fact >2 years old). Nevertheless it worked...
So thank you all for your responses and help!
Cheers,
Philipp

anybody selling parts from a broken g1? I need this asap!

thanks

Have you checked ebay for broken G1's? You might have better luck on there. Another thing I might try is calling tmobile and try to get someone who has authority to sell a broken G1, I'm sure they have a ton of them with all the people who brick there phones lol.

I have a G1 that I stole the mainboard from to replace a bad one. It was functioning, but had a cracked digitizer. I didnt really have an intention of selling pieces of it, but if I can recover the money I paid and help someone out at the same time, i would sell it. Sending PM....

gospeed.racer do you still have your g1's i need a long coaxil cable for the antenna not the little one the 80mm one if so can you email me a [email protected] thanks ill really appreciate it

Me too, lol.
The earpiece speaker is broken on my G1, I took it apart to see if it was a cable or anything like that but it didn't fix it. Id love to buy that part for $35 if anyone has that laying around. I'm not yet willing to buy a broken G1 for $50+ on ebay. PM me or txt / call 206.801.0359
Dan.

I sent you a PM. I have a friend that had a similar issue, the speaker was crackling. We actually were able to slide it in without disassembling the phone fully. The 3 screws for the lcd that you can get to were enough to gently flex it apart far enough too slip out the old speaker (they are double side taped in) and slip in the replacement. Tricky, but easier than opening the entire phone. Also, it is a good idea to clean the contacts while your in there- it is possible for the contact to get dirty and cause problems.

For the record, as soon as i get another phone to replace my MT3G, my g1 (my daugher is currently using) will be sold for parts. She'll get the MyTouch hand me down. I might be getting a cliq this weekend, so if anybody is interested PM. Id rather trade for any kind of QWERTY phone.
Its rooted, white with newer housing, the camera and gps dont work. Camera/gallery and other camera related apps force close.

part
well, sorry for being too late but my phone has the same problem and i searched around and found this site
globaldirectparts[dot]com/T-Mobile-G1-HTC-Dream-SD-Card-PCB-Board-p/htc730516.htm
but you will need to know how to put it in and have the tools to open your phone

[Q] Ideas to fix Broken Volume Key

In the process of trying to fix my loose hinge I must have broken my volume button. There is a tiny grey piece of plastic that gets pushed in. In the photo the volume button on the right is the up volume and works fine but down button doesn't have the grey piece.

Does anybody have any ideas? I would be ok with replacing that whole little yellow switch if I have to. I have a pretty fine soldering iron tip.
help please!

If you're lucky, you might find a tact switch to replace the broken one in an electronics store or in a technical assistance for mobile phones, or you can try removing the tact switch and redo with some plastic, its not that hard to do.
Good luck.

Do you know of an online electronics shop that sells tact switches like this?
What do you mean by redoing with some plastic?
I have an old Palm Treo 650 that I'm going to tear apart and look for parts. I'm not at home right now but I found this picture and the buttons on the top left look very similar to the Desire Z ones.
Does anyone know if there are any electrical issues about the switch that I should consider before using a different one?

I was a cell tech for 5 years and replaces tons of volume and ptt switches. You can use a switch from any phone to replace it. Voltage doesn't matter on these and all seem to be the same size. You could probably buy a broken desire z or use one from any old phone. My old word of caution would be that some phones use ribbon (flex) wires that have a built-in switch that wouldn't be compatible for use. I know a ton of iden phones (older ones like i730/530/610) use the proper switches. Maybe a local sprint store might have some old water damged models that would be perfect. It would have to be a service center though. Good luck!
Oh and any non lead based solder will do but be sure you solder it down good. It make take a few tries and before to pull on the switch a little to make sure it was a secure burn...
Oh... lol! The treo switch will work fine as a replacement. Be sure to not burn off the the soldering pad on the board of your G2. And carefull with the removal of the treo's switch. They break easily...

Thanks so much sino8r!!!
I had an old samsung that uses the ribbon button you mention.
Now I just need to find my old Treo. I was letting my kids play with it and I thought it was sitting the the toy box. Now I have to rip apart my house looking for this thing. =)
Yeah I got non-lead based solder but I think I'll need to get a finer tip to my iron. I have the Hakko 936. Any tip recommendations?
Also, there looks to be 5 solder points on the Desire Z switch. Two on each side and on behind. The behind one isn't really shown in my picture. Do you know which solder points are the important ones and which ones are for strength?
I hope I can document my progress enough so that others with the same problem can fix their phones too!

sino8r, is this the phone you were talking about?

Why would you want to use lead free solder? Leaded solder has a lower melting point and flows much easier. I mean honestly, just use what you have on hand, but is there a reason why you would specify that he use lead free?
