Based on my own observations and reading, the CRT in the HP 3562A is a marvelous piece of engineering. However, it literally fatigues over time and at some point the deterioration cannot be compensated for by the range of adjustments. The solution is to replace the ageing CRT display with a modern LCD. It turns out that SimmConn Labs has such a kit:

Terry at D-Lab Electronics did a good video on how to replace the original CRT with the LCD Kit from NewScope:

Terry does a great job of documenting the replacement process, so I will focus on the before/after results. I will start with original CRT images, followed by LCD images and by split screen comparison images. Since I also purchased the RGB to VGA adapter cable from SimmConn, I will conclude with an image of the 3562A screen displayed on a 19″ LCD monitor

This is a worthwhile upgrade/fix to keep an otherwise healthy 3562A running. Thanks for reading.
