Hi, i have a palm treo 680 but my screen touch is not working and i can?t pass by the configuration with the stylus...

Can anyone help me?

Thank you
 
B?rbaraRios, welcome to rabroad!

The "configuration with the stylus", is where you callibrate the screen touch with three little striped targets?

Start with the basics: put the device off, and clean the whole screen with a barely wet napkin. Don't leave any humidity on the screen. Clean again with a soft damp cloth. Next, get a business card and with a corner, clean the borders where the screen meets the external case. Now, do a soft reset by removing the battery, and try again to use the device. Please post back any progress :)
 
Hi, thanks for the replay, but my screen it?s really not working, so i would want to go directlly to the menu, because the touch screen it?s not working at all, and i have made an hard reset and i can?t pass anyway that first step.

Thank you
 
Geez, this is serious, then. OK. The Treo 680 allows to be operated on hard keys alone. you can navigate through functions using the keyboard and navigation keys. If you are unaware of any of these terms, please post so.

Put the device on, and get to the Preferences Panel. Under the General title, get to the Keyguard option and open it. In the lower screen, there are two options to disable the touchscreen. Uncheck either if they are checked, and try to use the touchscreen. If this does not solve the issue, it's most likely a hardware failure. A suitable repair option may be needed. In what country do you live?
 
I can?t do nothing of that because it is constantly asking me to use the stylus, and my touch screen doesn?t work so i can?t go to the menu or anything else. I think it might be a hardware problem. I live in Portugal.

Thank you
 
Welcome to rabroad, B?rbaraRios.

Did something happen to your device just before it started behaving this way? Did you install some software that might be causing this, or did you drop it? I had a Treo 755p. The touch screen stopped working as you describe right after I accidentally dropped it. The ribbon cable from the main board to the touch screen came loose. They were able to quickly fix it at the store. Anyway, if something happened to your phone that you think may have caused this, let us know.
 
Hi, thank you.
Yes, the lcd broked so i replaced it by myself, but when i did it, the screen touch was already not working but i could get trought the "calibrate with the stylus" because i made an hard reset, but at the same time when i get to the main menu the phone blocked, so a few days ago i went to a store and they told me that they could fix it, bue now i can?t pass the "calibrate with the stylus" wich i could before i went to that shop. So i think they have done nothing, or worst, they have aggravate the situation.

Thank you once again, and sorry for my english.
 
I think it sounds like she's stuck on the screen calibration screen, which might prevent getting to hard-key navigation.

I don't know much about Treos; but I know on my LifeDrive if you take out and put back in a memory card, it might get Barbara out of the calibration screen. Otherwise Barbara, why not do the Soft Reset as Hal suggested? You don't need the keyboard or touchscreen for that.

Barbara, if you have your Treo backed up, you can do a hard reset; but then that means 'rebuilding' your Treo as it was before from the backup (if you have one).
 
"I think it sounds like she's stuck on the screen calibration screen, which might prevent getting to hard-key navigation."

Yes, that?s totally right, and i have made a hard and a soft reset and i am still stuck on the screen calibration screen.

Thanks
 
Well, B?rbara, in the whole of possibiities, I reckon you can. But are you technically oriented? I don't wanna sound rude, girl, but that's where you come from, isn't that so :confused: ? You didn't mention the issue with a broken LCD and a DIY repair to me {slap in the wrist for you}, OK no hard feelings here :D , but if you expect our collaboration to be of some use, we gotta learn the hard facts beforehand. We could all have made a better diagnose without 'swinging from one side to the other', you know what I mean?

If you have already replaced an LCD screen all by yourself, then I reckon you're apt to do it again, but this time you're ready to pay attention to several other details. Just as Jig points out, affixing the screen to its connector relieves part of the issue. Now, the screen comprises two layers: one is the screen itself, I mean the output peripheral that provides image, and this is the "screen" in its own right; the other, a thin layer responsible for the tactile sensitivity, the input peripheral that makes the so-called touchscreen behavior exist, it's called the "digitizer". If you don't mention issues with the image quality or integrity, I reckon the "screen" was done allright. But the lack of touchscreen behavior is some issue in the connection of the "digitizer".

Jig, I remember some time ago, you posted links to a disassembly brochure for a Palm device. Are you in possession of a similar link for the disassembly of the Palm Treo 680?

B?rbara, if you feel with a high spirit so to attempt another DIY, OK girl, go for it. But if you prefer the reference for a repair shop, we can provide several.
 
ok, i am sorry for not mention that things, i didn?t think they were so important, my bad, and one more time i apologize for that.

I don?t know if i can open my palm again and do what you said, it sounds very dificult, but thanks for the help and sorry once agaiin.
 
I'm not sure which disassembly document you're referring to, hal, but there are various instructions and videos easily found by Google search for "treo 680 disassembly". It's not something I would attempt myself.
 
Your English is very good, by the way. I speak some Spanish, and while living in Mexico tried purchasing some electronics. I knew my Spanish wasn't very good, but was surprised that I could hardly understand the product description on the side of the box. I struggled hard to understand before realizing I was reading Portuguese! The Spanish was on the other side :rolleyes:
 
I think, Jig, that it was some set of PDF documents posted around, maybe in the guts of the Palm knowledge base, that you know is all garbled for the last year and a half. So for one any traceability to those documents has gone kaput, and for the second, I can recall what I've seen, but I can't always go back on my own steps, even in my memory :rolleyes: :D Oh well, never mind, maybe I'm just plain wrong and somebody else posted the links. The videos will do, anyway.

Well, people, B?rbara here is not in diapers when it comes to the tools. Girl, you followed a video, you disassembled your Treo device and you fixed it. OK, I'm gonna leave the effective result on the side. The merit is yours. I haven't done it myself, and so Jig says he wouldn't do it either. B?rbara, if you feel you will not be that lucky the next time, you are still on time to look for a specialized repair shop. I have disassembled several Palm devices but I was never lucky repairing a digitizer. That said, I have never purchased a replacement part to remove the original digitizer and install the other instead. And the fact that I wasn't successful of course doesn't mean you won't be either. It's your call.

BTW, there is another member from Portugal, here at rabroad. His nick is Bluefish, and he is a fine member and friend :) And yes, your English is very good.
 
Hello Barbara,
Sorry for the late response but I didn't notice your post. Maybe you already fixed it :).
But anyways I mostly just wanted to encourage you to re-open device and try again.
The first devices I took apart, like 10 years ago, totally freaked me out ..
I particularly remember when I opened up a sony clie and everything basically feel apart. Little pieces everywhere falling apart and I had no clue where they went at the time.
I was totally upset at myself. I let myself cool off for a few days, and went back to it.
And guess what, I got it all back together and it was working fine for years until I got tired of it.
Since you have the guts to open it I know you can figure it out.

Sounds to me like you should check the connector cable as others have mentioned - make sure it is seated correctly. It's happened more than once to me that the LCD will turn on but not respond, because it was not fully seated.

Second it's possible the LCD your purchased had a bad digitizer. If so I would go back to the source and get another.

If you can't then you could replace the digitizer, which is a more difficult job.
But I would start with the first two options and see how far it gets you.
