Sony and Screen

Sony and the screen are both new, and I only used them for a month. The Sony is new, I swear on God, if it's broken then it's ruined for you. And the screen is 19 inches, brand new, but the sound doesn't come out unless you use the headphones. Everything costs 400 including all the wires. The hand remote isn't included with the Sony. Whoever wants to contact me should call for 400 or 350.
