    Unhappy touch screen no longer working after drop; Help

    My son dropped my Adam on the floor. Glass not broken, adam seeems OK.
    However I am unable to use touch functionality of the screen or the touch buttons. Hardware buttons are working. But can't swipe anything.

    I restarted Adam several times with reset button, but perhaps there is a hardware problem.

    Anybody advice how to test and if there solutions to repair it?

    Thank you Borkata. That will be next step probably. Do you mean the cover of the audio or backside of Adam.

    I am first double checking not a software problem, do not know what my son did.
    So with reset button and volume + I managed to get into recovery. Then cache wipe and factory reset.
    Keep you informed

    Nope did not work. So I am afraid a connector for touchscreen broke down. I can can not slide my Adam open.
    Can I plug in a key board and use the cursors?
    Also good moment to check whether NI support is still alive. Lets ask for support ticket.

    OK with mouse and keyboard Adam is functional again. Adam shows true value of multiple USB ports now. So touchscreen functionality is broken, must be hardware problem.

    The choice is go for repair, wait for Adam II or buy new tablet.
    Your advice is welcome

    Alexadam, please clarify when your in recovery d0 the capacitive buttons work ? I know you can use the power button or the capacitive buttons for "enter selection" and the volume rocker for selecting/navigating up/down. Let me know if the buttons worked in recovery.

    The capacitive buttons and touchscreen do not share the same connector and it would seem to me that it is coincidental that both no longer work after being dropped. The capacitive buttons are connected internally by a five wire connector attached to a circuit board on the inside of the adam on the left side. This connector is extremely close to the USB port that the wire connector actually has to be bend slightly up in order to install. A piece of blue "tape" was applied at the factory for what I believe to keep the wire connector secure once attached. I have taken my adam apart several times and found that this connector does come out with little effort. The touch screen connector is attached next to the 3G card and does require wiggling it to remove, it seems to be factory applied quite securely. You can see a pic of the blue tape applied over the connector of the capacitive button connector here -> http://nifaq.pbworks.com/f/100_2827.JPG (by the way that links main page has a ton of info about adam and even shows you step by step with notes on how to open adam).


    Also a place to see a further breakdown of adam internals is here: http://tjworld.net/wiki/Android/Tegr...Specifications great reading and photos including some spec sheets.

    I see you sig indicates the screen has been replaced? Maybe if the connectors did fall out they may not have been fully secured when it was repaired (fresh sticky tape not applied to keep capacitive button connector from moving). My guess and only guess is that if adam hit the floor on the left, left top side, it may be enough to jar a connector loose IF it wasn't secured correctly and that would be a BIG guess.

    If your up to troubleshoot i would always suggest reflashing (not rebooting) a known working ROM after a full wipe including factory wipe. I only say that since another adam user posted an issue with bluetooth only working after he nvflashed back to ics but otherwise not reported as an issue for everyone else. I always try to exhaust all software fixes first.

    If you do decide to crack open adam use the link -> Notion Ink to help you open adam (any warranty is indicated as void once opened and it seems to be a year since your screen was replaced so you need to consider that). If your good at taking things apart very carefully then this is fairly easily done but a few people have cracked the screens trying to do so. If you felt the service and screen replacement during the last repair was good value then you could try again for a repair but that call needs to be made by you.

    My two cents...FIRST: try reflashing. SECOND: if still not fixed then i'd take adam apart. If i found the connectors loose i'd be concerned the repair shop who touched it last may have not fully secured the connectors and/or applied fresh tape to secure the one connector. THIRD: re-purpose adam to another use (stand alone computer) using the keyboard and mouse plugged in, not the same amount of fun but still useful.

    Hope it gives you some ideas on your choices.
