SOURCE: Convergence issue at screen edge

Sounds like a technician that failed to do the convergence alignment that should be checked after any repair. No nudging needed, maybe just nudge the technician who fixed it.

SOURCE: double vision and no convergence

I have found that fusible link FL231 is the main cause of this problem. It's located by the high voltage transformer and looks like a square coil.
Check it with an ohm meter and if it checks bad, then, replace it and you should not have to realign the convergence.
Any questions or comments, respond to this post and I will reply.

The picture curves in toward center of tv and looks like the colors are out of line.


These units had problems with there convergence power supplies. If the supply quits it will loose convergence correction. It could also be the convergence correction PCB itself. Have a repair shop check it out for you. Thanks

sounds like it is most likely the convergence power supply board, if it were just one color It would most likely be the convergence board itself

Convergence


No menu option is a clue to your problem. No menu option for convergence is due to the Micro not seeing a active convergence module in the unit. This is a post check, when the unit is turned on, and on some units, only done at AC power up.

With that in mind, you need to check your (PW=power) pcb for the conv module. This is easy to find, but on most RCA is located on the plastic panel that is in front of the CRTs. On this model, you should see PW conv PCB on left and Conv PCB on right. Top left corner is a plug with two wires, BP611, (i think) which should have like 300v DC. If you dont have the B+ go to the Primary power supply. More then likely you will have it.

If your 300v is there, order the PW conv module. NOTE: most of these modules are rebuild only and cost about 70.00 to rebuild at PTS. Other wise, you can trouble shoot at board level.

ONLY WORK ON THIS IS YOU HAVE CAN SAFELY USE A METER, AND HAVE SOME ELECTRONICAL SKILLS. NOT FOR BEGGINERS!

Check Cr4503 in the vertical circuit for short or leaking. The convergence circuit is most likely fine. Also check for any leaky electrolytic caps in the 500 block. (example) CR4503 will be printed on the PCB as CR503. The vertical circuit is located in the center of the chassis behind the big aluminum heat sink.
