(Press any key to wake up the screen. Keep in mind that pressing Power/End hangs up any calls in progress.)

2.Look closely at the screen, and if you can see a dim image, try adjusting the screen brightness (see “Adjusting the Brightness” on page 322).

3.If that doesn’t work, perform a soft reset (see “Performing a Soft Reset” on page 349).

4.If that doesn’t work, connect your Treo to the AC charger (see “Charging the Battery” on page 29) and perform a soft reset again.

5.If you’re using a third-party application, make sure that the application supports 320x320 screen resolution.
