Treo 600 When i touch my touch screen it does not respond to touch. I performed a hard reset and not i can't complete the reset because i can't get past the screen activation

Try running the Welcome program (under the system category) this utility will allow you to re calibrate your screen. I do this on my treo 650 (AT&T) whenever my clicking is off.

This can be difficult to fix, I supose the motherboard is fine since you can make calls and so on.

Must be the screen then?

There's apparently no known software solution to the dead screen problem. However one can bypass the screen setup step by doing a warm reset. See:

This is straight from Palm Support...
1.Press and hold the UP button on the front panel of your device.

2.While holding the UP button, use an unfolded paper clip, or the reset tool at the tip of your stylus, to gently press the RESET button inside the hole on the back of your device


3.The Palm Computing Platform screen will appear. Release the UP button when you see it.

Try running a piece of paper around the edge of the screen. There may be was something stuck in there, pressing the screen slightly and causing it to not respond to the stylus

try to open the case, clean the screen and the small frame carefully, reinstall and... good luck, mine worked this way.

You want to perform what is called a "Hard Reset"

It's pretty easy. You hold the power button while you push the reset button on the back. The treo will ask you if you want to erase all the data.

Unscrew the tip from your stylus

Locate the "RESET" hole on the back of your Treo 600

Press and hold the power button on the top of your Treo and then press the reset button with the stylus pin

Remove the pin from the reset hole FIRST, hold both for a few seconds, and then release the power button.

The screen will say "erase all data?", tap the up arrow to answer yes

Here is a explaining what I just said above:

That means your touchscreen is no-good at all. I had the same problem. Had to get a rebuilt 600 from Sprint (thank god for the insurance plan).

You may have dust accumulation around the edges of your touchscreen, between the screen and the case. Try using a can of compressed air. Gently press down on the edges of the touchscreen to expose the gap between the screen and the case, and shoot the air in there. This worked for me when my Treo 600 touchscreen stopped responding.

try performing a battery reset..it will reset the internal radio and the charging circuitry..only problem here is that u need an AC charger to switch the phone back on. this will wipe out all data u may want to back it up before trying this option heres how to do it Battery Disconnect Reset Treo 600 only A battery disconnect reset is a last resort step you can take to cut battery power, wipe all data, and regress a Treo 600 to its factory-fresh state. It only works on a Treo 600 smartphone. Important: A battery disconnect reset will erase everything on your smartphone, and also reset the wireless radio and disconnect the internal battery. All your data will be removed, and your formats, preferences and other settings are restored to their factory default settings. Don't perform a battery disconnect reset unless you've backed up your data, or you're willing to lose everything. You won't be able to turn your Treo 600 back on until you connect it to a power adapter, so do not perform this type of reset without your Treo 600 charger and a power source. HotSync note: Some third-party applications change the way your handheld backs up data. Other third-party applications do not back up data. If you have third-party software on your device, please contact the developer to learn what components are backed up during a HotSync operation, and if HotSync conduits are altered. Any data not backed up will be lost. To perform a battery disconnect reset: 1. Disconnect your Treo 600 from the AC charger. 2. Hold down the K and Backspace keys simultaneously. (Note: for French AZERTY keyboard, press K and M; for other language overlays, please refer to the customer support for your region) 3. While continuing to hold down the K and Backspace keys, press the RESET button inside the hole on the back panel of your device (where's the reset hole?). 4. Finding it hard to do? Good. We made this type of reset very awkward to perform, so that it would not happen by accident when your Treo 600 is jostling around in a pocket or bag. Sorry for the inconvenience. You might want to ask a friend to lend a hand if you find it too difficult to do by yourself. 5. Continue holding down K and Backspace. The screen will flash white briefly, and then go black. Release K and Backspace after this happens. Your Treo will appear to be "dead" and the screen will not turn on. If you see any activity ? such as the screen turning back on ? the reset was performed incorrectly; try again 6. To revive your Treo 600, connect it to the AC charger and plug the charger into a socket. The screen will stay blank for several seconds (as long as half a minute), then it will turn on. The LED will glow solid red, indicating charging. 7. Finally, follow the steps for recovering after a hard reset (a battery disconnect reset is an extended type of hard reset).
