Compaq 440 and 450 15″ and 17″ monitors. Where can I get the digital adjustment tool and software that plugs into the back of the monitors?
These Compaqs are Zenith chassis. If you are talking about adjusting the RGB values, only a few places (in the US) have that alignment software, and they will not share; they will want around $100 per unit to do the job. If you would rather try a workaround, you can probe the CRT board with a 10K resistor attached to its ground, to find the point that affects what you need. This probably will be near the base side of the driver transistor outputting that color signal to the CRT. Then you vary the value of this resistor (or use a trimpot), or raise the bias by attaching the resistor to Vcc instead of ground, until it adjusts the RGB to your desired value. Play a bit with the bright and contrast controls, to be sure the color stays correct, and if so, you are at the right point and can then wire it to the board.
