My Tv has No picture or sound. Tv was moved from another room to another, Tv was not bump or anything and the TV set is not but a year old.is there a reset button or something for this TV is a 42LG30


Hi.. Most manufacturers offer a 1-year warranty on equipment. If the Tv is less than a year old, I would recommend contacting the retail outlet you purchased the Tv from and have them arrange a repair from the manufacturer, with no cost to you.

You probably need a audio cable that runs from the pc audio out to the TV audio in. Radio shack has them so do a lot of hardware store and best buy.

Object thrown into tv screen


No, it will require a new screen & as the price of LCD TV's are dropping the cost of repair would be just as much as a new TV. It may be possible to buy a new screen cheaper on an internet site but you would then have to pay for someone to fit ti.
