Hi

I was looking at my projector today and found that the red tube was a little different to normal it seemed to be brighter, on closer inspection I noticed that when looking into the tube I could see a thin line zig zagging from top to bottom, if I turn up the G2 voltage this line can be seen on screen. Does anyone know if this is anything to worry about ?

Thanks
Paul

Turn it the other way your G2 is set too high.
To set your G2 turn the brightness and contrast down to virtually zero and adjust the G2 knobs until the raster JUST glows (you are not looking for picture information, just the raster)

I have had a play and found that it is the controller board. I also had a spare so everything is back to normal.

Roland any news on projector school yet ?

Without further info I'd struggle to put this down to the controller.

CRT school
I had to take a financial hit the last time I tried to organise one of these. I'd need a really good comitment from folks to do it again.
