I have a Samsung TXR3079 (chassis K62B).

After replacing the deflection board (had a noisy coil near the flyback, seemed heat sensitive though the picture remained good looking), it functions but needs geometry adjustments.

I cannot get the remote control to visibly adjust H-amp and H-PAR (which adjust horizontal gain and parabola geometry per the service manual). Other adjustments (V-gain, shift, barrel...) seem to work.

I am not a professional repairer, but was careful to not disturb anything but the board I replaced, and have the service manual (which is skimpy but does have alignment procedures using the remote control to adjust the various gains, etc.). BTW, I understand electronics but don't have any TV instruments at home to work on it with....

Any recommendations appreciated, thanks!
