Poor to useless input using the touchscreen. Cleaned around edges of screen with thin cards and no help. Digitizer does not work: Selected the "bulls eye" target over 450 times and it will not go away. Removed many 3rd party software and no improvement "ON/OFF" switch broken so I cannot do a Hard Reset.
? Any other way to do a Hard Reset. ? How to open the case so I can really clean around the edge of the screen ? Any other suggestions
"Power Digi" from http://www.palmpowerups.com/news.php. Try The 2 week trial then buy it for $16.95. Worked great. Don't let the trial run out without buying it because it'll be worse than before. Touchscreen failure is endemic with TX and some other Palm devices. I'm a faithful Palm customer for nearly 10 years but they're losing chunks of market share with this fiasco. I'm pretty much committed to Palm OS because of how much I use it for now. Still looking to switch.

Other than a bad digitizer (touchscreen) or connection, sometimes just a tiny bit of gunk/debris gets in that tiny gap that goes around the outside of the screen. That often results in the same problem,, a non-working touchscreen. Take a very thin edged piece if cut plastic as a "tool" to clear out gunk/debris from this gap around the edge of the screen. Some people even have used like the opposite end of a sewing needle (not the pointed end).
Many ppl have fixed a non-working screen simply by cleaning out this tiny edge gunk. Give that a shot as a first step. If you use care, you won't damage anything.
Then the touchscreen is most likely faulty and would need to be replaced, unfortunately you may have to replace the entire screen as it may be difficult to remove the digitizer from the top of the lcd display if its glued in.
It sounds like something I had trouble with before.
There is probably either a pinch in the unit (like it got slightly kinked when dropped, or there is some debris under the edge of the screen causing it to calibrate or touch improperly. I would suggest taking your drivers license and run it just under the edge of the frame. It should dislodge any problem matter and allow it to work properly but you will probably need to recalibrate your digitizer. Good luck!
This happens a lot with Palm digitizers. The only permanent solution is replace the plastic digitizer with an upgraded glass type. Before considering that, see if removing screen protector helps. (yeah, didn't think so. Worth a try!) Try Powerdigi, a better calibration program. Get it from http://www.palmpowerups.com It worked for me.
Search youtube for Palm TX Digitizer Replacement and Palm TX Take Apart Direction. If you think you can do it, or know someone who can, you can order a replacement digitizer on ebay for from somewhere like www.pdaparts.com.
Before ordering the part, you may want to start by opening the palm and cleaning the connecting ribbon cable contacts to make sure that a loose cable or oxidation has not caused your problem.
I developed the same problem after owning my TX for about a year and a half. I found an acceptable solution by experimenting with the digitizer. Instead of tapping the very center of the bullseye, I tapped off center until I found an acceptable setting where accessing functions anywhere on the screen would work for me.
Run a business card around the edges of the screen between the screen and the plastic housing to see if there is any trapped dirt or other debri. If there is, it will hold down that point of the screen and prevent any further input. Be sure to remove anything you find.
Also, sometimes the screen protectors themselves will shift just enough to cause the same issue. Be sure it is not wedged tightly between the screen and case.
My touchscreen was acting batty, not responding where I was touching. The solution for me was to: 1. remove my screen protector 2. Take a piece of paper, fold it in half, and scoop under the lip the case where it holds the touchscreen in to fish out debris that were distorting how the digitizer recorded.
Does the calibrator keep looping or not seem to work?
If you can access the calibrator, but it loops through the target
sequence (repeatedly asking you to tap the targets), there may be a
physical problem that's causing your touchscreen to be confused:
Do you use an adhesive screen protector? A screen protector which
is trapped under the screen edge may interfere with touchscreen
calibration. Occasionally, just having the screen protector on the
screen can cause the issue. Try removing the screen protector.
You may have debris trapped under the edge of the screen. Use
the corner of a piece of thin, stiff paper (copier paper works well) to
very gently slide all around the edge of the screen. Don't let the
corner of the paper travel more than an eighth of an inch under the
screen edge frame. By doing this, you may be able to dislodge small
particles of debris trapped under the frame.
A heavy impact or scrape to the touchscreen can cause permanent damage. If your touchscreen is damaged, you may need a repair
