You will need to replace the convergence amplifer chips and any related blown resistors, and perhaps two fuses.
Search this site for convergence fixes.

I have a ws-b55 and it has wavy green lines running through it all of a sudden any ideas ?? tony


This set has a common problem on the signal board. It's a small surface mount regulator that causes the waves. You can replace the board and have to completely map the convergence again or you can replace the regulator and get back to watching with no adjustment. Part is BA09, location is IC9C25. It sits just infront of the Terminal board and is right between 2 capacitors. Be careful not to ruin the board. If you have no experience soldering have a professional do it. It's way too easy to junk a beautiful tv such as this.

It needs to be repaired by having the convergence ICs replaced or resoldered (if intermittent).

Parts are STK 392-570. Be sure to use thermal paste on the ICs.

Mitsubishi 55411 projection tv has red band across bottom


go into the customer menu and select convergence with the original remote; if either the red or blue will not move in some direction, you have a bad convergence IC(the WS-55411 uses two STK-392-110 CONVERGENCE IC chips)

The kit comes with original Sanyo STK IC’S , not those cheap aftermarket or china made IC’S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

Red arching lines


is this that you are adjusting called convergence? If so then if it's really bad you can try to reset convergence, if not then the red needs to be aligned up with green first then blue on green. Can you provide a picture of what it looks like?

Red convergence wont move


if the red line is blurry and you have adjusted the screen focus control and does not work then you prob have a bad red CRT or bad red CRT fluid.........

convergence STK have nothing to do with the red being blurry
