I have a Symphonic TV,DVD,VCR combo unit that the remotes dont work. I have bought a new remote and it still doesnt work. Where is the reciever put on the tvs chasis? Is this repairable. Tjhis tv was built in 2003 the basic tv front controlls work but the remote does not. Any help would be most appreciated>
