Palm TX Touchscreen does not work

Hi,

I entered "Sys 0505" in the Search box on the main Palm support site and got a bunch of hits, one of which is a Palm Knowledge Base article which would suggest that the error might be related to a file (these hits suggest a backlight file though the last four digits of the error are different) which might have gotten onto your TX if you upgraded from an older Palm.

Hope this helps. If it's not the backlight file, it could be some other relic system file from an older Palm. You might have to try Hard Resetting your TX, renaming the Backup folder on your desktop, then Hotsyncing your regular PIM data back and reinstalling your third-party apps one at a time. This routine is the customary way to try to troubleshoot a software problem, which is prolly what you have. Now, if you have never had a prior Palm handheld and there's no way it could be a legacy system file from a prior device...I dunno...I would still suggest going the Hard Reset route, renaming your backup folder to backupold, Hotsyncing your data, make sure it's all working, then reinstall your 3rd party applications.

i had nightmares with palm, they were rude and basically did not want to know, so i will not buy palm again, howver date book fix it i read solved the problems, so i tried it and it found some 2k errors and then it has worked well ever since, palm complained to me that it wa a 3rd party item, so what they could not do anything but be rude and not help

I had the same problem with my TX.  When I moved, I lost the CD.  I think what you have to do is contact Palm to get a replacement CD.  It might be a small charge for it, but the drivers are on that CD and that will make it work.
Are you using Vista at all?

I had a similar same problem. It occured when pluging or unpluging in the USB cable into the bottom of the Palm TX when the other end of the cable was already pluged into a live USB port on my PC.
The solution was to make sure the cable is unpluged first from your PC before you plug or unplug the cable into the bottom of your Palm TX.

We have three TX's in our family with non-working power buttons. I downloaded the program Au Dodo http://www.freewarepalm.com/utilities/audodo.shtml and simply now use the far left button (button 1) as my 'power' button. It works wonderfully.

I haven't found out how to fix the calibration problem, but power on/off has been totally fixed. Good luck for you.

4gb is HCSD and will not work on a TX. 2 GB is the most it will read

HCSD card can only run in HCSD approved devices.

You could delete the software and reload it from the CD and see if that works.

What happens when you press the reset button on the back of the TX?

Change the screen. You can have the part here, as well as directions on how to change it:

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

Did you install any 3rd party apps?

First, reinstall the 3rd party conduit and related application. Next, check with the developer of your conduits to see if they have a patch or information on their software and the new Palm Desktop. If the problem persists, try the following: 1. Backup the c:\palm directory 2. Uninstall all 3rd party conduits 3. Uninstall Palm Desktop 4. Re-install Palm Desktop 5. Re-install all 3rd conduits. 6. Synchronize to test.
