The screen looks blue and i have tried the converence

You may have a component failing in the red drive stage possibly the blue as well or even the quadrature stage. A can of cold shot should help narrow the search considerably. It is also possible the red and blue projection tubes are nearing the end of their service life as well. If you have the means to test the tubes themselves, check the red and blue tubes for gas.

sounds like the converence is out, and that is why it is shuttin g down on you, and it is going to run around 350 to get repair. ConvergenceICs' needs replaced.

Convergence is dead.Must know how to solders?Must replaced 2 STK convergence ICS and some or all it resistors.Tries Websites Tv repair World.com,Tvrepairkits.com to buy a converence kit to repair it urself.The shop will cost u $300 for parts and labors.

You probably need to get a Sony TV Convergence Kit for your model. More information can be found using the link below.

converence power supply board is the most likely problem

If the IC's say have STK printed on them, then they are the convergence IC' s. should be three of them, replace all 3 , and the burned green coils, sometimes these burn as they supply the volts to the STK's. good luck, be safe..

You need to replace STK4278-L quantity 2 on D board
Above part is available in part store.

green is fixed so you have to move red and blue to green.
by using the remote you may find a simple converge function and open this and using arrow keys move the blue or red first to center of screen, repeat for other color you should see the lines moving toward a a white center point.

if the lines do not move with remote try manual ...menu on the set. if still no movement you have a problem on the convergence board and need a tech to fix.

A service manual will explain complex convergence to the detail .
but this might take hours to get it right.

maybe on your remote press menu and find converence and use the keys to move the red first over the green then move the blue over the yellow ..by standing back and just using the remote....should end up with white lines. and dont hit that button again once set. a tech should do this quickly and charge you minium.
