well i just got this new tablet running android 1.6 and i reset it to factory defaut then upon calibrating it said calibration failed and returned me to the home screen now the screen wont respond to any touch is there anything i can do
You could try to identify what it is, then reflashing the firmware: http://www.androidtablets.net/forum/specific-tablets/689-via-wm8505-android-tablets.html
i also have this similar problem with my tablet. below is my tablet specs. every time i calibrate it fails. also, i installed the market (applanet) and when i ran it nothing shows up except the top portion of the website.
