Hello, recently my HTC Sensation made a high pitch sound as I was receiving a call and it turned off completely. Now it won't charge or turn on. I replaced the battery, but that didn't help. I also tried the hard reboot (volume down button and power button) and got nothing. I'm relatively new to the Android OS so I'm not too familiar with it but I'm pretty sure it's an internal issue and not a problem with the charger or the battery. I've had the phone a little over a year so the warranty has ended. Could there be a problem with the motherboard or something else internally?
