As per Montgomery County:
Pennsylvania state law requires that televisions, computers, and monitors be recycled and prohibits disposal as trash. Some of the curbside trash haulers will pick up TV's for a fee. Check with your trash hauler to see if they are conducting a special electronics collection.
You can also contact a haul-out company like 1-800-GOT-JUNK or 1-800-HAUL-OUT or the GEEK SQUAD 1-800-433-5778 to come to your home to pick up your TV for a fee.
