If it is a sony check to see if any of those little green resistors are blown first. most sonys have the stk chips on the main deflection board.they will be next to each other with a big heat sink on each.have a soldering and desoldering iron ready as well as tape and marker for the wires.. remove the wires from the board you dont have to take the board all the way out. start desoldering each pin. if some pins are stuck just touch the pin with the iron. clean the heat sinks.apply themal paste to the new ics. put the new ics through the holes and start soldering. this part can be tricky. put the tip on the pin the solder will flow just quickly remove the solder then the iron 36 times and your done.

Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

This kind of problem occurs due to failure of convergence output ICs in Sony KP-51HW40 tv.
Replace convergence output ICs to solve tv problem.
This set uses two of the STK-392-570 IC chips for this (convergence problem)
Local tv repairman will do this job if you have no experience of electronics stuff repair.

Hi,
This problem is related to the Convergence controller IC called STK.It must get malfuntioning replace the STK IC with the same numer IC. But one thing is importent that there must be two IC STK's and you have to change both of them.
Thanks

The Blue and Yellow colors on the left half of the screen(looking at TV) will not adjust correctly. Sony Rear Projection HDTV-Ready TV about 7 years old...


its the problem of convergence on your television.so resolder convergence STK ic's. if that does not work, change (STK-ics).

they ar located on the main power supply board and there are two such ics on the board replace both the ics.and easily available in the local electrical shop.

You must have checked fusible resistor?
check convergance control panel and check voltage supply to this board.If voltage are o.k than you have to change convergance control ic which is smd ic and its on the control board.
