    I have a problem with no backlight on my keyboard. I had the same issue a few days after I got the phone, but did the soft reset and the problem was solved. However, today noticed the keyboard not lighting up when I unlock/text. Tried to reset, but no luck.

    The backlight on my Palm Centro keyboard does not work. I have tried a soft reset, but that doesn't work. It has been out for a week. I cannot text at night. It is annoying

    Hi, my AT&T Palm Centro's keyboard backlight will not come on when
    I turn the screen on - as it is supposed to do by default. My fiance
    has the same phone, which I set up for him, and his backlight does come
    on. What I can do is turn the backlight on by pressing the option+menu
    keys or make it brighter by pressing the option+p keys - I read the
    User's Guide & Manual from top to bottom. All the same, in a poorly
    lit room the keyboard is invisible and hard to find the option+menu
    keys to turn the backlight on. It is really annoying. Help.

    I have the same problem everything on the phone works even the lights on the keypad just not the lights on the screen. im ready to throw this phone into a wall. Can you help me

    I have the same issue with no backlight. Mine however, was the direct result of washing and drying the phone. To my surprise, every other feature works on the phone after a complete wash and dry cycle. The back light did flicker for a few days before finally going out completely.

    My question... Does anyone know of a good site to get parts and a good site to walk you through replacing the necessary parts (inverter or backlight)?

    My Palm Centro's keypad doesn't light up any more. This just happened all of the sudden. Really annoying and very unusable at night or in a dimly lit room.

    My keyboard went out last week. Cant turn it back on. Anyone know why this happens? Is it a malfunction or is this a defect Palm should take care of?

  • Anonymous Dec 16, 2008

    ever since i had gotten my palm, my lights didn't work on the keypad. i never really knew why, or even asked, which i probably should've. i went through all my settings, and can't figure it out eithter.


  • mderdrkd Jan 16, 2009

    I don't think Dr. Know's answer is completely correct. He says the LCD light is burned out. My son has a Palm Centro and the keyboard backlight won't light up while he is texting. However, we can get it to light up when we adjust the bightness. Therefore, it can't be burned out. There has to be a way to get the keyboard to light up while texting. Someone out there has an answer.

Sometimes we can resolve the issue by pressing the Options key and the Menu key simultaneously. The Centro Keyboard backlight would Turn ON.

The LED light has simply burnt out. I get those issues all the time with customer's phones. It could be a result of something they did or it could be a defect in the phone--nonetheless it can be fixed at a service center. You would need a new screen is all.

It wouldnt be good to do this yourself because once you get inside of the device there is a somewhat complicated wiring and alot of tape that you must pull up and you dont want to damage a wire if you dont know what you are doing. As far as parts, there is no site that I have found with genuine Palm parts.

How do i tranfer my contacts from my palm centro & another palm centro?

First, make sure you backup all of your data, including data in any 3rd party apps.
Sync your first Palm Centro with the Palm Desktop software to save the data.
Verify the sync settings in the Palm Desktop software to make sure when you begin syncing with the new Palm Centro, the settings for each application (contacts, calendar, memos, etc.) are one-way sync to the device, or you might end up overwriting the data in your Palm Desktop software with what's on the new Palm Centro.
When you sync your new Palm Centro with the desktop software the first time it will ask you to name the new device. If you give it the same name as the old Palm Centro, all of the data will sync to your new Palm Centro.
Search your computer for a folder with the name "Palm" in it to try and locate the name of your old Palm Centro, so you can name the new Palm Centro the same. When you locate that folder on your computer, it would be a good idea to simply make a copy of that folder as a total backup.

Keys on my palm centro won't work!

Some phones have a keypad lock so you dont accidentally hit the buttons if its in your pocket or something. Maybe try to go to settings and see if there is anything like that.

The touchscreen light on my centro won't turn on unless the phone is plugged in to an outlet

Sounds like a power setting? Try looking in the Power section of the options menu. Backlight during call is one of them.

Hope this helps,

Palm Centro - continous Syncing problem, now phone is dead

This happened to my palm centro and i fixed it myself. :) Maybe it will work for you. What i did was take out the battery and so the phone is completely off.. then take a tooth brush with rubbing alchohol on it and scrubbed the bottom part of it that the hotsync cord goes into.. I thought this may just mess up my phone more but i plugged it back into the power cord, turned it on and it worked just fine!! Seriously, try this out. It brought me so much relief!! And chances are you either got some **** stuck up inside there, or you got the botton part wet. Hope i helped!!

Palm centro wont boot

Do a reset. You will lose all items on you device.
Take battery out. Put it in and hold the power button on till you see the palm logo the second time. Release when you see the 2nd logo. It will prompt you for pressing up to delete and reset. Press Up. It will take some time to reset and reformat but please wait. 
After that your phone should come to the setup screen. I would hotsync after you setup to get your contacts  back.
