Hi all, Have a problem with my Acer LCD 3705. I've not had the tv long, its actually second hand but this is the first time that ive had this problem. The problem is that i am constantly getting a blank screen. I turn it on and after a second the screen automatically turns itself off and the tv sets itself to standby. Anyone have any ideas on what it could be? Its a good tv and i dont want to get rid. Thx.
