Greetings,
This is my first post here as I just bought a used SF2 CE Cabinet and I'd like to remove the monitor and the electrical stuff to replace it with a PC screen and hardware.
Here's how it (roughly) look:

Now, I read from left to right and hear from different persons that:
1- You need to discharge the monitor before removing it.
2- You just need to leave it unplugged and you can remove it safely.
3- You can get seriously injured from the shock of a monitor.
4- You'll simply get a bit shocked.
As you can see, these are counter-opinions and being an electrical neophyte, I really don't know what to think or do. All I want is to remove the monitor and dispose of it.
What's your opinion?
