This set, like most trinitrons- uses an HSTAT block for convergence. It controls the horiz converging of the guns, I did nothing to the crt neck adjustments, they were left alone. In all but the most extreme cases, I wouldn't tamper with those magnets, since it is a time-consuming and tedious task once you screw with em. (IMO). On this set, the HSTAT is deadcenter, connected to the fly's output and with the 2nd anode coming out the other side, connecting to the crt';s suction cup. The RGB background's are located near the antenna connections on the board under the tuners. In fact you don't even have to open the case to adjust screen, RGB background, Hstat, or vertical height.

Now, the drive controls were tough to find, in that you must put the set on its side, tuner facing upwards, with the back cover removed to access them. Make sure you don't crush the power/horiz board in doing this, BTW. The ACC control and the 3 drive's are located at the Bottom of the board with the background settings. My method is to do all the color controls and then set G2. I got great white balance and strong colors after this procedure. When I received the set, the picture was lackluster. Good luck.
