Please help me fix my problem on my HTC Desire HD. This morning, I was charging my said phone. While charging, I was also listening to Tune-In and browsing the Advanced English and Thesaurus (W) application. Innocently, I pressed the "More Dictionaries" menu option on the W application and my phone froze and the screen went black. My phone's buttons and menu options were not working, so I removed and pulled the battery and re-inserted it again. But, this procedure was to no avail because I still have a lifeless HTC DHD on my hand - black screen without lights - after the restart. What intrigues me is that my said phone rings and vibrates whenever I dial the sim no. inserted on it. However, I can't still receive the incoming call because the buttons and/or menu options are not working and the screen is dead. Please help me fix my phone. Tnx.
