Your Convergence amp ICs are bad. Heres how you fix It.
they are located on a huge heat sink inside your set. Just look for the largest aluminum heat sink inside your set. You will notice them they are large black ICs with about 16 pins on them. Just unsolder the old ones and solder in the replacements. just be sure to put some heat sink compound on the back of the new ICs where they contact the heat sink. You can get a de-soldering iron at radio shack with a rubber bulb to make the de-soldering alot easier and you will also need a low wattage soldering Iron to solder in the new ones. Just mark any wires you remove to get the convergence module out. That way you will know where the wires plug in when your finished. It will need a convergence adjustment when your finihed. Be careful not to bridge any of the pins with excess solder. Inspect the pins with a magnifying glass when your finished to make sure the solder from any adjacent pins arent touching each other.
