Question about Palm Treo 500 Centro

Sprint Centro Power Vision Problem

About a week and a half ago my data arrows turned white with a blue background. I cannot access any data at all, no updates to my news program, no web access, no email sending or receiving.
Normally of course the arrows are gray when no data is being sent or received, and animated when data is being sent or received. This is the larger set of up and down arrows next to the voicemail icon, not the two small left/right arrows above the signal strength. This still happens if I do a hard reset. Sprint had me do ##3282#, and all the settings they said to check were all ok. It won't connect to Power Vision or to Sprint Provisoning. Sometimes it has a timeout error, sometimes it just hangs and then cancels itself. I'm out of ideas!

SOURCE: Phone calls won't connect

I have the same problem with my Verizon treo 755p. It will dial but I can't hear anything from the other end. I can receive calls but when I answer, I can't hear the person on the other end. I guess I need to visit Verizon to have them look at it or give me another phone.

SOURCE: Treo 755p Frozen

this happend to me about a month ago, right after this, it went into the hotsync problem. where it would try to connect to hotsyc using the cradle, even though it was not connected. and I basically had no use of my phone unless I actually had it connected to the computer, but asuming that I wasnt going to be able to carry my computer in my purse, there was no way I would be able to use it. after battling it out with support tech from verizon, and the store, palm finally said it was a bad phone and put it on the system that i needed a replacement. so verizon had to honor that. well 5 days later i recieved my new refurbished phone. which was working fine until about 4pm yesterday. I am getting no audio from incoming and outgoing calls, the speakers do work because I can hear audio from videos and ringtones fine. so after the drama of hard reseting again, verizon said that it was a bad phone, and I will be getting refurbished phone #2 with in the next few days.  oh and anyone having this problem, after reading like a hundred forums, i came to find out that the connector for the usb port is very sensitive, any kind of moister, for water damage, to even having it in the restroom as you shower, can cause it to get a short in the port that it gives it enough of a charge that it's trying to start up hot sync. however the colored block problem also has to do with your memory card, but same thing, the ports are shorting out just enough to cause somekind of a malfunction. hope this helps

SOURCE: Palm Centro - no backlight

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.

If you do a hard or soft reset you'll loose the data on the phone but not the sim.

You can find the manual here:

Refer to pages 225 for reset instructions..

Hello salvidor72,
It's more effective to use a charger than the usb adapter. The web site has a nice deal on a Palm Centro PDA Phone Home/Travel Charger:
You may also do a google search for palm centro charger. I 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!!

My phone is slow all the time what should i do

you can always try deleting old txt, using a background from your phone, or bringing it to sprint and having the OS reflashed. but after a little bit of research the OS on the Centro is unstable and buggy by nature so there is a posibility that the phone you purchased is just a bad egg.

Unlocked Palm Centro

Are you still attached to a Sprint account? Or are you with another provider? If you are with another provider, you may not have the options of using the phone that Sprint provided ie. intrnet access or things like picture mail options. I know this occured with me when I used my Samsung device on another provider. I had to do a flash and only text and dialing out works on another provider. If it is still attached to a Sprint account then you should be able to call Sprint technical care and resolve your internet issue. But by the sound of it you are on another provider.

Download speeds on mobile centro

Your download speed on Sprint will depend on whether or not you are on Sprint's 3G network or 2.5G network. On Sprint 3G you should get 100kbps or better download (which is more than fast enough for mobile browsing). On 2.5G it will be more like 20-30kpbs. You can tell from the data icon at the top of the screen whether or not you are registered on Sprint's 3G network.

Can't Access Web or Email - Error 3000

I too have been having problems with Vision and live in the NE Atlanta area. When I first purchased my Treo 600, it provisioned instantly once I had Vision activated. It worked perfectly for about 2 weeks and then I picked my phone up one morning and noticed an error (The famous error 3000). To make a long story short, I spent 2 hours on the phone with a level 2 tech at the end of which he told me to take it to a local store to be reprogrammed. I took it to the Mall of GA store and they "reprogrammed" it and told me to wait 4 hours to try Vision. To my surprise, it started working.... until today. It has only been 5 days since they reprogrammed it and I am getting the error 3000 again. I am planning to take it back to the store tomorrow. This is getting ridiculous. The store said that a lot of people were having to have their phones reprogrammed to resolve Vision problems although the phone CSRs didn't know anything about it. Does anyone have any idea what is going on with Sprint? Is it regional?
