I think it is fixed!
For those folks in the future that google for Planar PD8150 Service Menu Codes or PD8150 codes or Planar Color Wheel Timing. or Planar 8150 Posterization or Planar PD8150 Banding
Service menu access is:
enter, up, down, left, right, left
BE CAREFUL DO NOT HIT ANY OTHER OPTION other than Color wheel delay and test patterns. Write down the starting number for the delay. I have no idea what the other options do, and since Planar won't give info to anyone but dealers and authorized service I would suggest staying out as you could brick your projector! Now on to the fix..
Use the up and down arrows to move and enter to select, left right changes values. Flip through the test patterns and you will vertical banding on some of them if the CW delay is your issue. Once you get back around through patterns to the SM, go up to the color wheel delay and change it 2 clicks one way or the other, cycle the patterns again.. continue till you see the banding getting better or worse, the goal is to make it go away . I had to change mine from 106 down to the low 90s.. Once it was gone, I I kept going till the banding came back and split the difference between the the two points where it started about which in my case was 90 but the number will never be the same between units.
Still need to verify with the local news and Jimmy K tonight but I thing it is good to go.
BTW Runco/Planar tech support says there are no hidden menus and you must send the projector back to the factory. They will only give the date authorized dealers and service centers..
UPDATE Problem has been corrected all content looks as it should, solarization is gone!
