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.

A Photograph is provided below:

The Component I cannot Identify

  • Why don't you just ask the technician? He should know what parts he disassembled. ;)

the 6 components on the top are buttons... don't you have 6 buttons on your CRT? if so, it looks like he replaced the buttons' PCB.

  • The buttons on the CRT is working just fine right now. So if it is what you say it is, it did not affect the button behavior at all. Jun 22 '14 at 10:00

    Most likely he replaced some other PCB and the replacement came with a replacement button PCB. That may be your original one or the new one he didn't use. Jun 22 '14 at 10:02
