This is an ITC 222 chassis and what happens is the flyback High Voltage transformer develops bad solder connections and blows a small fuse located next to it. To repair, first UNPLUG THE TV and after taking the back off the set look for the board that has the big red wire coming out of it and going toward the inside of the tv. The big red wire originates from the High Voltage transformer. Care has to be taken to remove the board which is clipped in by plastic tabs. Also remove plugs that hold the board back from turning the board upside down. Be careful with the two ribbons and remove and put back carefully. When you get the board turned upside down look at the connections at the bottom of the High Voltage transformer...they will appear to have rings around them which look like the solder it not connecting on some of the pins. After soldering the pins if you look just to the right of the transformer (looking at the component side) there will be a couple of small brown boxed shaped components. These are fuses. If you have an ohm meter and turn the board to the solder side again and measure continuity across each of these fuses and one of them could be open and not measure continuity. Since it would take a while to get a fuse like this I use a trick: I get an AC power cord and strip it back with my knife and get just one small strand of the copper wire and solder it over the bad fuse. I strand like this is about 5 amps. After doing all this put the board back in its place and plug up whatever you unplugged and turn the set on and the double image and bow should be gone. If not then you have a convergence power supply board bad which is directly above the board you fixed to the far left. But most of the time it is just as I mentioned: the solder connections and the fuse

The picture is showing a double image and is distored.


The problem you are refering to is more than likely a convergence problem. The convergence circuit in your tv is controlled by an IC (integrated circuit) stk392-110 and it makes the 3 colors (red, blue, green) line up/converge together to create a clear picture. You'll know when this part needs to be replaced because the picture you see is 3d looking and possibly bowed on the top or bottom or on the sides in any or all 3 colors.

51mp392H/17...bowing and color alignment off


Take the TV to a repair shop. It sounds like the convergence chips are bad. Be sure they change them as a pair or you'll wind up with the same problem again.

Image Distorted


This is a classic convergence problem. Please confirm that your model is 51H84 and whether or not you intend to repair this yourself. You will need to know how to solder. If you wish to attempt the repair, confirm the model and update this and I'll provide you with details and instructions.
