Question about Panasonic PT-47WX42 47" Rear Projection Television
Turned on the tube and am now seeing red and green bar areas at the top and bottom, along with seeing these red and green areas offset (like a convergence problem). Is this the evil STK392-180 chips gone bad??!! Thanks
Replacing the two STK392-110 ICs didn't do it for me. But you can try. I am experiencing the same problem, and it appears that is not possible to correct the problem with the ajustments in Service Mode. Please let me know if you find a solution to this problem. TIA.

The problem is called green geometry.There is nothing wrong w/the green pix tube.It is critical to get the green geometry
accurate because the red and blue convergence overlays on
the green.If you have more than an alignment issue,that will need
repair before adjustments are attempted.
