question about removing isolation transformer and power distribution block

[64bitmatthew]

I recently posted this question in my build thread, but as its a hypothetical question, I thought I'd post it here to see if I could get some other peoples thoughts and discussion about this as opposed to the build.

So I've been trying to research and learn about these machines, and I came up with a hypothetical situation.  I wanted to run it here though and get more knowledgeable members thoughts on why this may or may not work. 

Its in regards to a 1996 Midway hangtime arcade cabinet.

In theory, if someone was to switch from a crt monitor to an lcd monitor, they could delete the isolation transformer, correct?  The purpose of the isolation transformer is to clean the electricity going through it, and to isolate the wall outlet voltage to keep it off the metal frame and ground connections of the monitor as a safety measure.  But an lcd screen doesn't require this, as the chassis is isolated, so its fine just taking normal / wall outlet power. 

Now, the idea of deleting the isolation chamber gets a bit tricky as the cord leading away from it (on the hangtime cab) leads to the power distribution block.  This then has leads going to the crt montor, as well as the switching power supply.  But the power going to the switching power supply, does it have to come through the isolation transformer and then the power distribution block? or could it just receive power from a wall outlet like a regular computer switching power supply (as this one is in fact a computer one)?  I was just thinking of whether it would be possible to delete the isolation transformer, power distribution block, and have virtually an extension cord come in to power the switching power supply and lcd monitor.  Nice and tidy and updated. 

Thoughts?  If that ramble made any sense lol.
Thanks!

If all that stuff is working, I fail to see the point of removing it.  You may want to convert the cabinet back to CRT some day.

No, you do not need an isolation transformer for an LCD.

Yes, you can take all that out and replace it with a power strip and extension cord.  Strip can power your LCD and switching power supply.

Thanks for the speedy response! I appreciate you taking the time.
As mentioned, it was more of a hypothetical question, to help me learn.  It's not really the proper way to get a cab running, but the crt currently doesn't work, so that is what lead me to think of this as a possible route.  This is an option I feel I could handle at this point, where as crt repair is not.  I also live in the middle of nowhere up in Canada eh, so I don't have a lot of resources around to help me fix the crt.  I'm not saying I will go this route, just trying to see if my logic was correct on this possible option.
The wires coming off the power distribution block, those are only monitor and switching power supply correct?  Everything else such as speakers, marquee, etc are through the wires going to the jamma board correct?
Thanks again!

Your marquee is going to be directly wired to the AC line.  The connection is probably being made at the cabinet's power switch.
