Mitsubishi Big Screen 65-711

Had my big screen out for repairs. After the tech completed repairs,
reinstalling the "light box", my picture is off center. ( high and
left, showing a white line at the bottom, and chopping off the left
side slightly)
Called the tech back but he did not know how to correct the problem.
Are there adjustment screws to realign the picture? Where would they
be located?

Thanks,
Richard

If he got the light box mounted correctly, the adjustments for picture
alignment are electronic, not mechanical. Focus is mechanical, though
(turning the lens barrel), and should be checked and touched up whenever the
light box is handled.

You should probably find someone else to do the service menu adjustments
since they are rather complex. If the TV is to give its best performance,
this needs to be done, as well as to correct the alignment problems that you
see. You might want to read about "ISF calibration" on the web.
