Replace STK-392-110s or 150s upgrade with 180s replace both ics.

You have a convergence problem;

Blue wave coming up frpm the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

Behind the front cover you will see a little plastic box with six phillips headed dials. They only move 180 degrees. The three on the bottom control color richness and the three above them control focus. Turn all three of the bottom ones to the left while the TV is on, then gradually turn them to the right until you get the color you want. NOTE if any one of the three bottom dials are too far up the TV will shut down and will continue to turn off after about 10 seconds after start up until the offending dial is turned back a little.

If you have gone into the customer menu and red or blue are skewed and will NOT adjust in some direction you have a convergence circuit problem.

Simply put--this model uses two of the STK-392-560 Convergence IC chips. What needs to be done is both need to be replaced and the set then adjusted with the Sony Remote.

If you can solder and are handy you can buy a pair of the chips on Ebay for about 12 dollars plus shipping.

I can give you detailed instructions if you or someone you know can do the repair--most shops are going to get 300 or more for this repair--maybe not worth doing on a 43 inch set?

These are good sets and unlike the LCD or Plasma sets this is about the only problem they ever have.

The reason the chips fail is they have a metal back and are each bolted to a metal heatsink with fins to keep them cool--a white grease is applied to the back of each chip to quickly transfer heat--after some years the grease dries out and one of the chips fails.

Only two things are needed to do the repair--being able to get at the chips and being able to unsolder them, replace them and solder the new ones in.

I have helped dozens of average people here do repairs just like this......if you are able you can save the set and and a LOT OF MONEY.

I can tell you the best place to buy the chips and also tell you everything you will need to do the repair from start to finish.

I am in California and had someone 50 miles away call me with a similar problem in a Sony--he got the parts today and I stepped him and a friend of his through the fix over the phone for free--

Let me know if you need help or want to do it--I am here to help people.

If this helps you rate this solution as I do this here for free.

SOURCE: how easy is sony kp-43ht20 converge ic chip

Easy is not a good description... due to the cabinet size of this model, there is not much room to work. You will need to disconnect a lot and unfasten a lot of wires so that you can pull the chassis out of the lower cabinet. Then you will need to remove the D board screws and the Convergence amplifier screws (the amp will be right in your face, you can;t miss them... 2 large heat sinks right in a row. After you do that, you will probably need to change 1 of the 2 fuse links on the G board (the board the power cord plugs into). These are the supply Vcc for the convergence amps. They are 5A fuse links located on the upper/mid, right side on the PCB. Use caution, you need to discharge the circuit before you place the fuse in or you may pop the new (or remaining old) fuse. it's best to use a 100 ohm resistor to bleed the circuit on the input side of the fuse. You can do this by touching a legs of the resistor to the fuses legs. To be sure, just do it on both sides of the fuses. (resistor touch to fuse 1, side 1... and also to fuse 2, side 1. Repeat on other side of fuses.) Bleed for at least 5 seconds. After that, change the fuse(s), put it back together, power it up... press the Flash Focus button on the front of the TV. It you need to do further convergence, you can find information all over the place... or post it here.
