Ok.... it's MY turn to yell for help.


I have a GP3000 I recently picked up for a song. NO burn whatsoever. Bright as blazes. Only trouble is that the top right corner blue convergence is severely distorted, and will not respond to normal or point adjustments sufficiently to bring it into range. It's only the top right corner, about 4x4 squares or so in the test pattern. I am scratching my head on this one. The unit appears that it has very few hours on it, as it's SPOTLESS. Hmmmmm......


I don't have a manual for this one.... It is set for front, floor projection. Are there any plugs for changing the polarity for the alignment coils? I don't see the usual plugs, only the ones for the yoke, and they are correct.


Thanks

I know im stating the obvious.. but i assume the raster is nicely centred on the blue tube, is it?

YYYYYep.

Does it only occur on the internal test pattern? Or is it present on external video sources as well?

 

[Tinman]

YYYYYep.... both


Just got off the phone with Doug.... going to try a few things tomorrow.


Hehe... let's see you make THIS look better.
