Just recieved a 50 inch Zenith flat screen television. It is heavier than heck though so that leads me to believe that it is an old television. the previous owner said that it needs a new y sustain board or something like that. I work for an IT company so i know a fair amount about electronics but televisions i have never dealt with. When you plug it in you can hear that it is on but no video will come up. I wouldnt mind investing some money into it but not a whole lot, just looking for a little more info on it and what the problem could be. thanks alot in advance!
