HI Guys,
Please send advise.

I guess it could be the V board, but far more likely the controller board or the convergence output board.

Just want to report back on this, after watching movies and netflix with no side corrections for a month.
I swapped in my spare controller board.
I can now do the side adjustments.
Thanks Curt ,you were spot on, it was the controller board.

i made a mistake,
The keystone and bow or side correction adjustments is still not working,
Changing the controller board only allows me to make the fine left side correction only.
Which means only the left side of the screen is not askew.
I have now changed the convergence board and v board , it is still not responding to adjustments.

ok, this time my 909 issue is really. Its the SMPS that was the problem.
After swapping three controller boards, two convergence board, two v boards,one H board to no avail.
I swapped the Smps out.
I can adjust the east to west bow and keystone.
Hope i can get tips on what to look for in the smps board ?
