Treo 650 microphone turns off when screen goes blank

When making or receiving a call, after a period of time like 30 seconds, the screen of the phone goes dark. When the screen goes dark, the person I am talking to can no longer hear me. If I tap the screen to turn it back on, the person can hear me again. Drives me and the people that I talk to crazy.

Treo 700w-Blank screen

You may have a faulty screen

Have you tried a HARD RESET?

Perform the following steps:
Pull the battery out. Put the battery back in while holding the RED button down and a reset screen will appear.
Push the up button on the five-way to start the reset process.
Alternate process:
Similar to the hard-reset of the Treo 650. Remove the battery cover.
Press and hold the Red radio button.
Use the stylus to depress the reset button next to the battery.
Push the up button on the five-way when you get a prompt to "Erase all data".

Replacement screens are available on ebay.

Bueno, trata lo siguente:
If you purchased the Treo in the U.S., you should have the English to Spanish option when you reset the phone. Just make sure to back up your data before resetting it.

HotSync the Treo 650 to your computer to ensure that you have all of your information backed up. You will lose everything on your Treo 650 with a hard reset.
Step2Press and hold down the red phone key on the right side of the Treo 650 keyboard until the Palm screen appears. This will begin the hard reset. Step 11Let go of the red phone button when you see the Palm screen. Step 2Read the screen prompt carefully. It will ask you to press the up arrow key to proceed with the hard reset or the down arrow key to abort. Press the up arrow to continue with the hard reset. Step 3Wait for the phone to reboot. When it comes back on, it will ask you to select a language and walk you through the same introductory screens you saw when you first got the phone. Step 4HotSync your Treo 650 to your computer. When prompted, select your old username to restore all of your contacts and information. This should complete the hard reset process. jQuery('.Article .Steps .Image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); }); Tips & Warnings
  • Do not forget to back up your data before performing the hard reset. If you don't, only the data from your last HotSync will be able to be recovered.
  • After performing a hard reset, install your applications one at a time to make sure each is in working order. Delete any applications that are not in working order, as those might have caused the need for the hard reset in the first place.
Buenas Suerte,

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

Treo 650 phones turns off by itself

funny thing... the older palm treos like this one have some glitches. these glitches can normally be fixed by changing some of the settings.

1) go to your home screen, and select PREFS
2)select power
3) set your brightness level all the way to the right (NOTE: it takes more power to dim the screen then it does to brighten the screen.)
4) set auto off after: to the highest number allowed

please let me know if this helps!

Treo 750 p

Personally 10 to 15 minutes is not normal, I have had my 755p battery get hot after a couple of hours of straight talking, but not right away.

I would just take it back where you got it and tell them the problem that you are having and get another Treo. I have owned all of the Treo's ever made and they make great phones.

It does take some getting used to but the pros vs the cons of owning a Treo are much greater. Blackberry has come along way with their phones and if you are used to the Blackberry then the Treo just might not be the phone for you.

To get back to your question if the phone getting hot is normal, no, but it will happen from time to time when talking on the phone for long periods of time.

Hope this helps,

Treo 650 "Dead Screen"

Try plugging in your Treo as if you were charging it.

Then click the reset button in the back.
This should reset the charging mechanism inside.
See if the Treo starts to charge again after that by letting it sit for 1-2hrs.

Cannot hear incoming call or caller cannot hear me

First check and adjust call volume. It should set be optimal and secondly during a call adjust the microphone volume. If this is ok and the problem exsist then the microphone, speaker or some other hardware need to be replaced. Contact local hardware expert.
