Hello I am new here so please bare with me. i recently bought a used tsu6000 from tweeter for 100 bucks(they were going out of business 60-90% off ) It doesn't have the battery but, I already ordered one. My next problem is i put in on the docking station plugged in the ac adapter and the screen comes up on tv but, the touch screen doesn't work??Meaning I press something on the the touch screen and nothing.The volume buttons and the channels buttons work because the remote icon is moving. Is it broke or will it not work with out the battery or could it be locked?? Somebody please help.

thanks in advance for any help.
