The Nintendo had nothing to do with a convergence problem. It could be in your conv generator board, but very unlikely. Chances are it's in the ICs.

Go in and find the conv ICs, they will be mounted on a
big heatsink and the wires going to the conv yokes will
most likely plug in somewhere closeby.
Conv ICs are the workhorse of the CRT RPTV, and it is
not unusual at all for them to need to be changed out
at some time in the life of a CRT RPTV.

PS -
The wires for the conv yokes at the CRT necks are the
thin ones. The thicker ones are for the hor and vert
sweeps, which must never be disconnected from their
circuitry during
CRT operation.
If your beam loses sweep on any of the CRTs, it will
instantly score/gouge your phosphors on your CRT faces,
vaporizing the phosphors there and ruining the CRTs.
The beam is very powerful, but in normal operation
moves incredibly fast, not damaging anything. Any
slowdown of the movement of the very powerful beam that
draws the picture, acts like the searing vaporizing beam in Tom Cruise's War of the Worlds.

Convergence is off - Blue and Red are fine Green will not line up


On most units, the Green is constant and the Red and Blue are adjustable. Here are 2 links on how to manually adjust the convergence. There is a menu option using the remote control. Once there, you will find step by step procedure on how to adjust the convergence. Hope this helps answer your question. All the best!

Sounds like possible solder connections on the convergence ICs. If so, you will see the red, green, and blue not lining up on ever input and even the mits menu. If you can bump it to correct, its just a solder connection, but if its out all the time then the ICs need replaced. This is a difficult repair only recommended for skilled technicians (40 solder connections + possible re-alignment needed)

Mits 55908 Convergence problem


Good Day, John;
It sounds like the Convergence IC's have poor solder connections, by re-soldering the convergence output IC's should solve your problem. The IC's are large and mounted to large silver "heat sink" with STK 392 # on them. Good Luck, big IRISH.

Red blue are separated


Good Day;
From what you say it sounds like the Convergence IC's have failed. Part number 267P150010, STK392-570, replace both IC's. They are on the middle board secured to a large heat sink.
Good Luck, big IRISH.
