The beeping sound is the power supply trying to start up. That means there is a short somewhere inside the set somewhere. On these TV sets most of the time this trouble is in the horizontal sweep circuit. Sorry but the only way to reset a TV set like this is to unplug it for several hours and replug in the set, but in this case I doubt very much if it will work. If you have no solid state repair experience then please call in a pro to assist you in this repair as there are no user replaceable parts inside these sets. Let us know how you made out. Good Luck
