A general fault is that the touch screen or its control devices has failed. In some cases, the ribbon cables or the pressure contacts between the screen and its controler are not making good contact.

If there is an electrical fault, the fix is to replace the touch screen, and its controler. In many of these types of phones everything is on the main circuit board. The general fix is to replace the main circuit board, or to replace the screen assembly.

The main cause of failure for these devices is dropping the phone, or getting it wet.

Hi i have a HTC touch Pro2 phone i need pc suite software.... i want to put song , videos etc in htc phone so plz tell me where can i download this Pc suite software...


HTC Touch P3540 / P3452 doesn't come with PC Suite. You can download the software named "Active Sync 4.5" from Microsoft. The software is available on Microsoft website at below link -
http://microsoft-activesync.brothersoft.com/microsoft-activesync4.5

After installing make sure that you are creating pairing between your PC/Laptop and HTC Smartphone. Until this is completed, you cant transfer any of your media files to your phone.

Do let me know if the problem is resolved or not.

Thanks,
Amar

No, you can't bypass that screen. The only way is get new HTC Touch Diamond unlock code and remember don't try to put wrong code again and again it will cause your phone in hard locked state. Go find new HTC unlock code then put that code in your phones. I hope my answer can help you, thank you.

I set a cosecurty code in my htc p3700 but now when i enter that code it is not unlocked


Are you sure you enter correct code? IF yes maybe your phones need to be reset. Try to call your network provider and asking him about HTC Touch Diamond P3700 unlock code, don't forget to explain your situation and you need needs 1-2 weeks before you get that code and it takes a charge. Or you can try buy instant HTC unlock code from third party sites with lower price and more quick turnable.

How i connect my note book to my htc bia bluetooth


Hi,this is a detailed step on how to connect your htc to your notebook via bluetooth. STEP 1. Turn on the bluetooth of your htc which is accesed at the connnectivity settings of your phone.
STEP 2 Ensure you also put on the bluetooth on your notebook,most notebooks have a single button in front of the keyboard,to turn on the bluetooth. STEP 3 You now go to the bluetooth settings on your phone,and click on 'add device'.when you click on it,it requests for a pass code,when this is done for the first time,this pass code can be any 4 digits of your choice. STEP4 After entering the pass code on the phone,a pop up shows on your notebook requesting for the same pass code you entered on your phone. Ensure you enter the same pass code for both the phone and notebook,if not the devices won't pair via bluetooth.
STEP 5. After entering the pass code on the notebook,the notebook is automatically paired with the phone via bluetooth,afterwards you can be able to transfer files between the phone and the notebook via bluetooth.
Thanks and take care
