Green converge lines are gone!

I recently had the ics replaced to fix the pin cushin effect and now when I got to re do the convergance I have no green lines for the first stage of converging..... green writing appears and green arrows but no green line to match up with the cabinet.

Any ideas???

Re: Green converge lines are gone!

When you are in factory convergence on your hand unit press buttons 1-9 usally 1,2,3 theses should show r,g,b patterns, try them and see if your green is there,

I have a Mitsubishi WS65611 I understand that the green lines are fixed and the red and blue lines are somewhat adjustable my green lines are no longer fixed in the top right and bottom left of the screen ...

YES, you either have a fuse that went out or the convergence IC went out... Sometimes it just comes unsoldered and causes the same effect. You need to locate this "IC" and tap on it with something non metallic. Like a ruler or a stick. While the tv is running and crosshatch is up on screen. If the lines get close as you tap on the IC or bang on the tv. then fuse is good and the tv might just need to be resoldered on that CONVERGENCE IC. Let me know how this works for you and if you have any questions give me a call @ 502-773-7969 and i can help u out further.

There is a blue shadow to the picture. The color chips were recently replaced and it has been doing this since the replacement. I have tried to adjust the convergence but on the screen with the cross hairs...

STK ICs that were replaced maybe the reason convergence is not lining up or you may have some open low ohm resistors that need to be replaced ,near convergence ICs. STK392-570.
Mats Electronics has STKs for 14.95 each

The green convergence line is warped (undulating) and renders a double image that can not be corrected through the convergence menu since only red and blue can be adjusted that way.

You have a convergence board that is bad. At its best you may have to resolder the ICs, as rings around the pin will indicate a poor ground. On the other hand you will need to replace two convergence ICs and a few low ohm resisters.

Convergence way off!

Yup, you lost convergence. The only fix is to repair/replace the convergence IC. Some techs will just replace the whole video board.

A repair facility will charge 400 to 600.00 for the repair. Or you can repair it yourself if you can solder. As both convergence ICs need to be replaced. They are STK392-110 you can get replacement ICs at the following link with free instalation instructions with pictures so you can do the repair yourself. Heres the link.

Green and red colors is out of line panasonic pt51hx42

This is a convergence problem. Either there are bad connections on the convergence ICs or the ICs have failed. Try resoldering the pins on the ICs first. If that fails to resolve the problem, replace them, These ICs are large black ICs attached to a heatsink and are most likely marked STKxxx.

The red and green do not converge on screen. tried auto convergence, does not fix the problem.

There is a problem with the convergence ICs. Either there are bad connections at the pins or the ICs themselves are defective. If you can solder, resolder the pins first. If that does not resolve the problem, replace the ICs. These ICs are large black ICs attached to a heatsink. The should be marked STKxxx.

PT 47 convergence IC's? box? both?

Always suspect the IC's first, digital convergence prblems are actually pretty rare IC's go everyday. I'd check partsore .com Generics usually work fine, they are probably STK392-110's but check to make sure.
