Can you not tighten it in place after adjusting your joystick anymore? And obviously after cleaning your projector, it most likely is just not perfectly "square" to your screen now... skewed and not parallel ...and it may not be level .. both in left/ right axis and up and down axis. And make sure that there any menu setting of keystone is at the default.
Yes the joystick won`t lock when turning it clockwise. It can`t tighted it, exactly. Skewed and not parallel, yes.
Maybe it should have been loosen before working on the PJ?
I do have a theory on the “skewed and not parallel picture”:
- I might have been holding the PJ so that the physical lens touched the working table with a little pressure, and that got it skewed.... is that possible?
I have the service manual, but disassembling the PCB board, to get down to the back of the joystick, is way over my head. And I don`t know how to get it lined up correctly anyway.
I don`t use keystone.
The picture ALMOST fit the screen, but is skewed ... i need to turn the PJ on today (it`s morning in Denmark right now) to get a good look at it again.
It would be nice to get some clues how to correct this, if possible, without opening the PJ.
