The dreaded convergence problem

Thank you for your help. I did find a burnt resistor. I replaced that resitor and now instead of the left (facing the front of the TV) end of my blue line curving downward it is curving upward and seems to be somewhat squiggly at the end. The blue line can be moved in all directions now and have tried the 9 point convergence adjustment and still cannot get rid of the curved blue line. I have checked the rest of the resistors on the convergence circuit board and all seem to be in the proper range. I even tried to move the rings on the Blue Gun.....still have the curve.... Is it possible that it messed up one of the IC's when powered up with the open resistor? How would one determine that? Since the Green, Red, and Blue connectors are the same, would it be possible to swap the connectors at the circuit board to isolate a possible bad Gun??? Would any of these tests or questions be covered in the Service Manual? Thanks again for any and all help.

I guess my original message is gone...maybe I did not know how to reply properly. Yes that was the first thing that I replaced. The replacement of both STK's made no changes at all to the picture. Originally I could not move the blue up and down, only side to side. After I replaced the open resistor all control was regained, but only with a curved blue line.

thanks

My red line will not move left or right, it will move up and down. I have no idea what to look at or where to even start looking. Please help

Did you replace the stk's?

make sure your yokes not shorted ohm them make sure you get same reading on all 3. Does this set have Digitel convergence?

Red color off to the left

Thats a convergence failure. often you can replace the two Ics and associated resistors to repair the issue yourself instead of replacing the convergence board. But you can get the ICs and resistors from www.tvrepairworld.com which includes free tech support for help installing the parts. They also have circuit boards for most models available if you choose to replace the board instead of trying to repair it.

Hi there i replaced my hitachi 53uwx10ba convergence IC (2) stk392-120 and now it won't turn on and just flashes at the front panel 7 times, can i get some help pls

Did u check the pico fuse and all those resistors on the tv convergence board to make sure with ones are good resistors which are not good resistors and replace all them resistors too?U didn't do that should get it tested and replaces all those dying resitors.Try website like Tvrepairworld.com look up ur Hitachi tv model what resistors and pico fuse u require to check.

RCA TV CHASIS ATC321 HAS BURNT RESITOR BY FLYBACK WHAT BOARD IS THIS NEED A PART NUMBER OR CAN I JUST REPLACE RESITOR #R14705 ITS BURNT IN HALF THERE IS NO OTHER SIGNS OF DAMAGE OR BURNING

you can try just replacing the resistor, but I'm afraid you have other issues too because of this burnt component

I have a jvc av48wp30 tv and need a wire diagram

Looking the convergence board from the side of the resistors (The chips will be behind the resistors), you have from de left to right:

1.5 ohms, 150ohms, 220ohms, 2.2ohms, 3.3 ohms, 220ohms, 1.8ohms, 220ohms, 150ohms, 150ohms, 1.5ohms, and dispose horizontal in relation of the other resistors (the one near to the Ic is 2.2ohms and the other is 220ohms).

Hope this helps...

Bending red lines

your convergence Ics and convergence resistors need replacing. You can get the convergence ICs stk392-110 and the resitor kit for a JVC at the following link with free instalation instructions.
Heres the link.

Re:hello again

resistor replacement is very easy compared to IC replacement. You have to unsolder one side of the resitor and lift that side out of circuit in order to test it properly and if it doesnt measure its open and will need to be replaced or if it reads more thatn 5% of the rated resistance it will also have to be removed as the resistors are all 5% tolerance or less in convergence circuits

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?

There will be around 12 resistors all identical 6.8ohm that will sometimes go open if they dont have color bands they will be marked as 6R8 1WJ which means 6.8ohm 1 watt 5%

CONVERGENCE?

you can not tell anything about those resistors by sight get an ohm meter and test them. Disconnect the three plugs going up to the Yokes first though or you will not get an accurate reading. Check the resistors around the blue yoke plug closely this is where you will find your problem.
