I have an old CRT Display that used to dim out every morning and would require significant warmup before it reached normal brightness. A repair guy worked on it. He did some stuff and asked me to notify him if the problem reappears again. The Display is working for now.
After he left, I discovered that a PCB component left outside, which I suspect is a CRT Display component. I'm posting / linking a Photograph with my Question so anyone savvy with Display hardware can identify it and tell me if it's anything crucial or am I entirely mistaken.
