Dammit, I had to change the housing for my HTC Hero GSM Unlocked, and though I believe I didn't break/crack or damage anything, especially the speakers, after reassembly my speakers are not working any more, no more audible ringtone, sound notifications. Everything else is working fine, and with earphones, I can hear everything. I even re dissembled it and couldn't find anything that was broken, or loose, or damaged. Can anyone anyone point me in the right direction please! OR anyone know where I can get a new HTC Hero GSM version internal speaker? I tried on eBay and couldn't find anything. are there HTC repair centers around NYC?
