Remote control will not operate tv even with new batteries and can't change channels

SOURCE: Remote signals

If you tryed a universal remote , that remote should have at least worked the volume and the channels selector. It could be whats called a remote sensor assy thats mounted up toward the front of the set on the inside between the buttons. Its not really a user changeable part as there is soldering involved to replace the sensor. Realisticly, the correct way to trouble-shoot this set is to look at the data or logic line coming out of the remote sensor with an osilliscope to see the data and if it goes all the way to the microprocessor IC. If it does and no remote operation happens then the Micro's bad. Theres way to much Hi-voltage in these sets for a handi-person to tinker with, and its advised that a tech take a look at this set for you . Sorry I couldnbt be of more assistance. Good Luck
