Regarding the handling of CRTs:
This is not something that an amateur should even consider. It should only be done by someone with the proper training and experience. I won't go into any details because at the end all you would have is a little knowledge. And as the saying goes, a little knowledge is a dangerous thing.
Over the years I have replaced many CRTs so can speak from experience.
After doing some research I will agree that a CRT can store voltage. I wlways grounded the flyback connection to the CRT before I handled it so both the flyback and now I know CRT did not have any voltage. Working on broadcast monitors I once got zapped by putting my hand to close the the HV while it was on.
When I've called my ISP (Comcast/Xfinity) they always tell me to turn off everything for 2 minutes. I've got ahead of that, I turn it all of before I call.
"Mr Britton I don't see your modem"
"It's off because you always want me to turn it off no matter what the issue."
"Turn them back on please."
No, I just said I gently drop PSUs in water (in an iron container on the grass outside) before disassembling them to see if there is something fixable (usually to change the fan). You have a better idea? I cannot reach the capacitor's contacts in any way before it's fully disassembled and I'm not going to take risks. I'd rather risk damaging the PSU than myself. I can guarantee that it does no damage to PSUs (if you take the time to dry it well with fans before assembling it again and powering up).
I don't know about CRT, but I suggested it because in case you cannot reach the contacts due to casing or whatever making the disassembly at risk of electrocution, water could be a solution.
