You don't adjust convergence through a service mode on one of these sets. With a conventional CRT, convergence is done by physically adjusting the convergence rings on the neck of the tube, and the position of the deflection yoke near the bell. You would also need a crosshatch generator to provide the required test pattern for adjustment.

I think my convergence is off. Just the green and red seem to look off. I do not know how to adjust each color. When you go into the convergence setting under the menu and it just does like an automatic...


You will need to know How to Enter the Service Menu to bring up the Convergence Pattern in order to adjust the Convergence,another thing is it depends on which chassis you have RCA had bought the right to use the name Zenith, when in fact these TVs had RCA Chassis and not Zenith Chassis
Remove the back to Tv, Make sure TV is unpluged and look to see if you have on a board Located on the right hand side
2 Big Black ICs they will have Part number on them example STK392-570 these are your convergence ICs that need to be replaced.You can exchange this board for new board at Zenith exchange moduels 1-800-632-6637
But if you have the RCA Chassis then you will have 2 bottom boards one on the Left hand side will be the Deflection board it will have the FBT flyback transfomer on it and their is 2 Ribbons that connect to the board on the right handside which is the ssb board that has your cable/AV input jacks on it.and their will be 2 boards above the 2 bottom boards if these are the boards you have then you can with Tv Off Press and Hold vol- and ch- wait untill TV comes on,release buttons and then you should be in the service menu to adjust convergence manually. R/G/B
For these chassis PTS rebuilts boards 1-800-844-7871

How do i make all the colors sync up to get rid of yellow and blue shadowing


Go into the customer menu with the remote and select convergence; if red or blue will not adjust in some direction you have a convergence circuit problem----depending on actual model number set uses two convergence chips--they would have to be replaced.

If the convergence does adjust in the customer menu but not good enough I can give you the sequence to get into the tech menu to fine adjust-remember if if will not adjust in the customer mode, it will not adjust in the tech mode either.

See attached photo of Philips convergence problem.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

I have had this problem before and restarting the reciever fixed it. Just push the red button under the front panel of your reciever, or unplug the reciever for a minute or so.

Adjust color convergence automaticly


I hate to tell you but if the colors are not aligning the way they used to is because the set has developed a problem know as a convergence problem,you should be able to align the colors (red,Blue)but if they are not going in is because the covergence IC's are going bad,If you are familiar with electronic service you can do some of the work yourself but sometimes still does require the help of a servicer to do the aligments from the inside,if you are not too familiar be safe and call for assistance.
