    Please check your solder work with STKs as might be bridge solder in some pins.

Yes. double check for bridged solder or open as well. If everything checked ok, disonnect the related convergence yoke and see if it fixes it (do this very quickly tho). dont let the set run more than a few sec! its a good idea to scope the output too.

My magnavox projection tv has convergence problem.

there are 12 6.8 ohm 1watt resistors in your model. There could be more blown resistors as they often wont show any outward sign of being bad. It could also be the ACS board which is defective if the Resistors are good.

You will need to replace both STK392-120 convergence ICs and about four of the 6.8 ohm 1 watt resistors. The following link has the replacement ICs and resistors and they provide free instalation instructions with pictures.

Burnt resistors

Depending on where you bought the ICs you could have fried the new ICs when powering it up with burnt resistors as the green is controled by both ICs one IC controling the horizontal green Convergence and the other IC controling the vertical green convergence. Have you checked all the convergence resistors out of circuit?

Did you check for open resistors coming out of the ICs. These commonly go open when the ICs go out. The are located right next to the ICs there are numerous resitors all with no color bands very easy to locate. Check these resistors.

Covergence problems . Could be loose contacts on the output IC's or bad IC's . If they are bad they generally also have bad resistors or fuses that open up as well .

Service Manual PT-51HX41E Needed?

If you haven't the technical ability to repair this set I suggest to get a tech to replace the stk392-110 convergance amp ic's. these ic's are very noticable they have the largest heat sinks in all the sets ic's. but the problem may not be the ic's alone, there may be several resistors open or open pico fuses. So if you are not technicaly inclined donot attempt this repair. it's not just the replacement of the ic's that need be done but geometry and final convergance in the service menu. please leave this to the pros.
