Basically I have a CRT with no service menu. I really wanted to try doing something I've wanted to do for ages, so I desoldered the internal adjustment potentiometers and replaced them with pots of the same value but mounted them on the back of the case.
Thankfully the CRT really handily has a horizontal adjustment anyway, but I also added horizontal size, with pincushion and trapezoid. I also drilled a small hole as the TV has a vertical size pot, but it was facing the rear anyway so that seemed simpler. The locations seem a bit random on the back as I had to be careful of locating the adjustments where the was physical space behind them.
Probably a bit unnecessary, but I play a lot of PAL and NTSC content and it's really nice to be able to adjust them so easily. The only thing I have left to do it print some knob covers that remind me what each does...
