Does it appear 3D color alignment issue? If so press menu and see if the convergence option is still available under the picture settings. Then let me know and I will assist you with the problem.

ok here is the scoop there are 3 fuses on the deflection board to the lower right of the flyback transfomer they are square and brownish on of them is open you can have tehm replace with a 4 amp pico fuse and check the solder joint on the flyback this can cause the fuse to blow

The ITC 222A red CRT drive board from www.tvrepairworld.com should fix that issue.

flyback 270125 repair kit from www.tvrepairworld.com should fix that issue. The kit contains the CD with instructions.

Convergence is dead,must replace covergence it wth convergence kit,what in that kit.U know how to solders?Tries thes websites Tv repair world.com,Tv repair kit.

The color wheel is likely bad and needs to be replaced.
Check this link it is for a samsung TV but the same principals apply

If the convergence option is still in the on screen menu its usually related to resistors on the convergence power supply board

The ITC222 and ITC222A convergence option missing repair kit should repair that issue. The kits available at www.tvrepairworld.com and contains the parts and CD with instructions

hook up the wires properly and?

The fuse blows when there is aproblem with the convergence board - if the TV just had issues with the convergence b4 you soldered and replaced the fuse then the set should not be dead - I would check all plugs especially the 2 flexible (short) cables that jump the (ssb) two boards together. Do you hear the HV trying to start (a little chirp sound near the flyback) If so the set is in shutdown mode if not then power supply problems are usually the cause - check for swelled capacitors in power supply.

Your symptom sounds like a damaged convergence IC, whick you have found to be true.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

You will also want to replace the white heat sink compound that is on the heat sink, just scrape it off, then clean the surface with alcohol. Then apply a thin coating of fresh heat sink compound, if you do not do this important step the new IC's will not last long as the old compound will act as an insulator to the heat transfer.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.
