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 ^^

After getting a white screen, I did the fix of placing a small plastic by the black square chip, and assembled again, not a problem with the white screen anymore.
But I just had another problem, after assembling the phone back again, some keys on the keyboard stopped working: "O" "P" "L" and "Enter", and the key on top of the "I", looks like a softkey, but the other one works fine.
All of the rest of the keys work fine, but those 5 keys don't.
I checked for any dirt or something obstructing the keyboard chip, and the rubber, but nothing seemed bad.
I alo tried putting 3 sheets of paper cut in the size of the chip, but that didn't help.
I do use the keyboard, does any1 have an idea of why this is happening?

Usually complete failure of certain keys is down to one of two causes
1.
The ribbon cable is damaged - (think it unlikely unless it was cut or severely bent)
2.
The ribbon cable connector is not seated properly or needs cleaning or is damaged:

Worth re-seating that a few times just to be sure - and it only needs the back casing to be removed (maybe you've tried that already?)
Mike

Could be buildup of corrosion between the keys and the Keypad. Visit Mikes site in his sig at bottom of his post to find the illustrations and instructions on what to do but make sure you test Mikes suggestion first. Cleaning the keyboard contacts is a more intensive job then just reseating the connector...
Cheers...

Yeah I was going to try to remove the white sticker as he posted on some other threads, but trying to remove the sticker seems hard and scary.
But, it seems very strange, that this happened after fixing the white screen issue with the small piece of plasti card.

The card shouldn't affect it as the keyboard is in the bottom half of the Hermes and the screen is on the slideout section. The thing that could have been hurt is the ribbon cable that attaches onto the mainboard Or the connections at the back of the LCD.
So saying though, I have found strange effects from mainboard problems messing with the LCD (my flywheel pcb broke and caused no backlight on LCD). But I wouldn't htink it would work the other way as it would be the mainboard where problems would originate, not be the byproduct.
Cheers...

Yeah, the card should not be a problem as I thought.
I have another hermes, which had the white screen, but at the time, I did not know how to fix it. The problem is that, I had issues with mine because it did not charge or power up anymore, I think the problem was the use of different chargers not made for the Hermes.
But anyways, I'll try to switch the keyboard from the old one into this and see if the problem lies with the keyboard, or cable. I'll try this tomorrow, and let you know guys about this.

I always find its easier, if you have the parts, to replace... Its when you have no choice you have the hard time..
Cheers...

Wow.
I just tried changing the keyboard from the old device into this one, same problem with the same keys... Then i said, ok, it must be the cable, so switched cables, and the same issue still :|.
I just had reset the device and it's still not working.
This has to be something else..

Possibly motherboard... You could try replacing the other MB, that is if it still works, other wise the connector may need to be cleaned - both on the MB and on the ribbon.. Use only isopropyl alcohol (surgical spirits) and a cotton bud. Never use Metho as it leaves a residue.
If that doesn't work then it must be the MB as you've tried changing the keyboard and ribbon. Little else to cause the problem.
Personally I'd try the mainboard as its fairly easy and doesn't require that much more effort than what you've already done. Remember though that you will have ALL the old data on the other phone. Old OS, settings and contacts...
Cheers...

Faulty Xperia - Ideas

Hi guys, I appreciate that this may not be the correct Forum but I get alot of knowledge from this site so if you guys dont know, no one will!!
My Xperia optical pad/joystick is having a mare...each time i rub my finger over it, my X1 trys to dial out and skips to menus. The phone has apparently become "moist" acording to the Vodafone shop (Which to me seems like an excuse)
I ahve wiped the device back to factory settings and the same errors keep happening. I have turned the Opt Pad off in settings but the pad still reacts to touches and just jumps though menus and try's to make calls!!
Is there a way that I can get this fixed or resolved or has anyone else got any ideas. This may be a hardware fault.
Thank you all.

Well I can imagine dust being behind the scroll 'wheel'. How about you try to blow it out with a can of compressed air?

Hi,
Thank you, I have used a can of air and this seemed to make little difference.
Maybe I could get the device apart and give it a pro clean although I feel the actual joystick me be capput :/
Other ideas?
Thanksagain.

Moist? The only way I can see a phone becoming moist is either from a bit of rain or sweaty hands. Either way, phones are designed to withstand this otherwise they would be completly useless for outside use..

I have the same issue. It does seem to happen more when I have been using the MobiPocket Reader to read a book for a while ... maybe my sweaty thumb is causing the issue ;-)
Seriously though, if this is really true about moisture I may have to trade my X1 in, it drives me nuts when this happens.
Is there a way to clean the optical joystick properly? (I'm going to try the air-from-a-can idea as well)

Autoscroll, the best feature in Mobi

Nah, AutoScroll just irritates me , get distracted for a second and you lose your place.
I've resorted to using 'tap the screen to go to next page' option. Seems to work well BUT the point is the X1 shouldn't have this issue.
Vodafone have offered to 'repair' it for me, since it's still in warrenty, but it means sending it away for 10-14 days and in the meantime they can give me a 'loaner' which will of course be a peice of crap (I'll just use my TYTN).

Update:
I have found the issue! After looking on Google I came across a YouTube video of how to dismantle and reassemble the X1.
Turns out one of the transistors on the Optical pad circuit board had become slightly coroded, so I cleaned this up with a small soft brush and a minute drop of meths and put it back together and BINGO!
Also while the screen was out I left it overnight in airing cupboard in a ziplock bag with a pack of Sylica(Spelling) Gell.
Search YouTube for: "Xperia assemble Front/Back" User; CKY1
Hope this goes to help someone.
Cheers guys

in my case, I just adjusted the joystick to lower sensitivity...It worked without surgery..

so technically vodaphone was right. and it was a moisture problem.

[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?

Axon 7 Repair

I dropped my Axon 7. Though there's no visible damage, the phone will frequently freeze (not turn off) and just continue to display whatever was on the screen at the time. Or the the charging LED will remain on if it was just charging and not actually booted, even if I unplug the phone.
I opened it up and reconnected all the cables, but no luck.
Once it starts, if left gently on a table it will continue to run, but if I jostle it it will likely freeze.
I've been experimenting and know I get the same behavior if the phone is running on AC with the battery disconnected (I think that worked...) , or if I run unplugged with the battery.
Any ideas? Since I already have the phone open and don't much have to loose, I'm willing to attempt more surgery, but I'm not sure how to diagnose the fault. (Yes, past the 2 year damage warranty).
Happy for your thoughts and suggestions!

There was a post on here with the exact same scenario, if I remember correctly it was a cable to the screen/display.
I've dropped phones and sometimes the pins bend slightly so check the connection pins.
I even repaired one that fell into a bowl of milk

found something?

Assuming this is the issue, does replacing this cable mean removing the screen? I've heard that's hard...

I can't see from the pic properly but it is possible, the only way to know for sure is to compare with an original condition unit. (Looks better than some I've seen)
I was fortunate enough to have the same phone as a backup so I could check in my case.
Just make sure all connectors are snapped into place and no broken fragments in the connection.
I hope you get it sorted
