For the last couple months or so, I've had issues with my NEC PG9 in that the convergence was off every time I turned it on.
I would fix it by using the Point function. It would stay put for the evening (4 8 hours) and then when I turned it off at night and on again
the next day it would be off again. I Googled the issue and found that it could be the capacitors on my convergence board and would
need replacing. So i searched for a fix specific to my issue and found nothing.
I remembered reading somewhere that my Point convergence should be no more that 4 clicks off, in otherwards if it took more than 4 clicks to align the grid, it would
need to be tweaked with the other controls and not the Point board. So I decided to zero out the pointboard to see where I was at. Whoa, it was off at least 1" in some spots, so I tweaked everything
back into shape and was able to get it within an 1/8 inch or better.Then I used the point control to finish it off, I need no more than 3 clicks on the remote to do this.Its been very good the last few days.
So, anyway, my advice is to tweak your projector without using the point control to avoid this drifting issue, or zero out the point ocasionally and redo it as described above. So I didnt mean to get so
windy and type a novel about this problem but I think it is good advice, WHAT DO YOU THINK?
