    check fuse at location fl231 next to flyback, check pin 11 & 12 for cold solder. If neither of those you will probably need convegence power supply.

What if my tv dosnt convergence option


Thats a common problem and easy repair. You can get the ITC222 and ITC222A convergence option missing repair kit from www.tvrepairworld.com which has the parts and the CD with repair instructions.

How to install a convergence kit in R61WH76 chassis no. itc222a


That model doesnt have the normal convergence components that nost other sets have. There are no convergence ICs the convergence is actually affected by three boards within that chassis it can be deflection board related, Convergence power board or the convergence amp board. Based on your TVs setup menu diagnosis will determine wether a component needs replacement or wether a circuit board will need replacement.

Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and also check the power resistor, if values are not exact you have to replace them. These ICs are located behind the black heat sink; you can see once you open the back off the TV. The convergence board should be checked for cracked solder joints and please make sure to check the resistors as if they are shot the ICs might blow again. All this is only recommended if you have electrical expertise and know how to solder/re-solder components, if not then you should get this done by a professional. The typical cost to get this fixed by a pro is around $250-$300. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Problem could very well Be in your SSB board the one that connects to Deflection Board on Left side and convergence board mounted above it? When I get the time will do some more CK-ing on it, I have 2 of them Now that i need to get back into on repairing them,they also have wierd problems.

Your symptom sounds like a intermitant or damaged convergence IC.

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. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

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.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

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.

Sounds like your talking about an RCA HDTV with the ITC222 or ITC222A chassis. If so the ITC222a Convergence option missing repair kit at the following link will repair that issue. www.tvrepairworld.com

These sets do not have convergence ICs it has convergence board most common problem with them is if you go to menu then setup and do not see convergence on menu then you have a open fuse FL231 they are located on right side of FBT flyback transfomer thier is 3 in a roll small brown rectrangler looking caps but are FUSEs it will be the one in the middle.

RCA R52WH74 (ITC222A Chassis)


no the board that has the FL231 on is the ITC222 deflection board. The other board is above the chassis in a seperate frame that runs across the set the convergence power supply is the board on the left above the board where the fL231 is. Yes the ITC222 and ITC222A are the same chassis. As for the service manual that site should have the service manual under the thomson category as the ITC 222 chassis is actually a thomson chassis made for RCA.
