Blue Convergence wont move left and right

Near the middle of the chassis inside you should see two large metal heat sinks---the chips(2) are black and about 2 1/2 inches wide x 1 1/2 inches tall and should have the STK-392-110 NUMBER printed on them in white.

The hard part of this is first you have to unplug several cables so you can get the entire chassis tilted up so the bottom of the boards face the back of the set. You have to unsolder all 18 pins on each chip AND 4 metal pins on each heat sink--when you replace the chips(apply heat sink grease to them) the hard part is getting all the pins on the chips and the pins for the heat sinks lined up so they go back into the board.

Then holding a heat sink and chip in place solder each chip/heat sink back in.

IT IS A VERY GOOD IDEA WHEN YOU REMOVE THE CHIPS TO CHECK ALL THE DARK GREY RESISTORS AROUND THEM---most are 1.8 ohm 2 watt---they can be checked like checking a fuse--if one of them is open you will still have the same problem if you do not find and replace it---they are protect parts---if one is open--one of the chips got it.

After you replace you can go into the TECH menu and fine adjust the convergence--you can do the same in the customer menu but the TECH menu offers more places to adjust and saves these adjustments---I have instructions for getting into that menu if you need them.

If you can do the repair yourself you can save a lot of money as most shops get 300 or more for this type of repair--a pair of the chips can be bought on Ebay for about 12 dollars plus shipping.
