My aria htc screen stopped working yesterday. I have tried to reboot it and it is still nonresponsive. The buttons work, alarm is going off, and incoming calls are coming in but the screen is not responding at all. Please help!

Hi,
you can try by updating your phone
if the problem remains try factory settings(back up your data)
Mother board has to be replaced from an unauthorized service center.

Please note that all data will be deleted from the HTC Aria as a result of this procedure. This process does NOT delete data stored on the microSD card. We recommend backing up all of your personal data before proceeding.

1. Turn the power off. If your HTC Aria is frozen, pull the battery out and reinsert it
2. Hold the Volume Down button
3. Hold the Power button until the display turns on
4. You are now presented with a menu that allows for Fastbook, Recovery, Clear Storage, and Simlock
5. Select Clear Storage by pressing the Volume Down button
6. Press and release the Power button to select
7. Now simply confirm your decision: Volume Up for YES and Volume Down for NO

If you selected YES, all data including third-party applications will be deleted from the HTC Aria. Once the wipe is complete, the phone will reboot to its factory fresh state.

Hi,
If you are trying to use a SIM card in your phone and getting a message like "Enter Subsidy Code", "Incorrect SIM Card", "SIM not provisioned" or similar messages, then you need an unlock code for your mobile phone. You can get HTC Aria Unlock Code from the network provider, they will verify the account holder information. You may check this HTC Unlock Code site, they will provide you an accurate code fast with easy to follow instructions on how to unlock your phone. Once your phone is unlock, it will work with any network worldwide without sticking to one network.
Hope this is helpful.
Thanks.

You can get it repaired by sending it to them and they'll send it back fixed. It's pretty costly though.

Hello, im not sure where they actually can repair that in indiana. I know wireless image in denver can help you repair that but you will have to mail them the phone. 303.482.1288
