You need to replace chemical type fuse marked FL231 part number 259213, it`s located next to the flyback transformer, theres 3 of them there but 231 is the only one I`ve seen cause your problem, replace it and you`ll be all set.Happy Holidays !

Convergence issues in this set are generally divide among three diffrent cuicit boards. THere are adjustment that can be made by service techs in service mode if that is problem. However if it is something electrrical it generaly take replacing on these boards. then a alignment process. All is dependant on which boards have to be replaced

Go to menu then setup look for convergence if it is missing on menu then you have a open FUSE/ FL231, But if you have convergence on menu then go into service mode turnTV off then PRESS and hold at same time ch- and vol- wait for set to come on then release TV should now be in Factory settings.

The model number of your TV probably falls under the ITC-222 chassis design. Do a search based on that criteria and it should point you in the right direction. If I remember right, you need to replace FL231 on the deflector board though. Good luck

Bow tie looking picture with 3d color mis-alignment

you have lost convergence. First thing to check is to see if you are missing the convergence option in the customer setup menu. if you do not have this option then i suggest reading the article in the tips and tricks section entiltled "the fl231 fuse problem" this is a common and sometime easy repair if you do have it then you might need a convergence power board

R52WH74 WONT CONVERGE

first question is the picture also bowed in on top and bottom. if so you may have the common fl231 fuse problem if you do consult the fl231 problem under the tips and tricks section. if you dont then you defently hav a convergence issue. the thing to look for is under setup do you have the autoconvegence option if you dont then you have that problem.

The convergence circuit is the problem. If you can solder and are comfortable working inside the set where there are potentially dangerous high voltages even when unplugged, you can fix this yourself. First locate the convergence ICs which are large black ICs attached to a heatsink that will be marked STKxxx. Try resoldering the pins on these ICs first. If that fails to resolve the problem, replace the ICs. Please note that there could be additional small parts that require replacement as well. Start with the ICs and let me know the results.
