First off i got a little carry away on this post, if its too long tell me and i will revise it:
Thanks Elutz, Thats a good peace of info knowing how to spot if the monitor need a ISO or not. i went down to my garage and out the four non-working monitors i have i could instantly spot which ones needed an ISO and which ones didnt. except for one its a 19" monitor i bought brand new and have never been able to install it with out having a "what i think is" a high voltage wave going through it and the bottom of screen getting cut off. but ill get to that later so here's a run down on the monitors.
Non-Working Monitor 1:
25" Wg-25k7191
This monitor needs an ISO for sure this was the sparker when pluged it into a non ISO cab
It doesnt turn on after that but i have a flyback, capkit, hot coming from bob roberts for this monitor so i hope to have it working soon.

Non-Working Monitor 2:
25" NeoTec
this monitor does not need a ISO but when i plug it in the yoke lites up and after about 30 sec the picturs shows up on the screen but its rolling and super blury and no adjustment did any to make it playable but im hoping a cap kit will fix this problem.

Non-Working Monitor 3:
25" CMG-2500
This monitor also does not require an ISO, the problem with this one is the screen is green i was told the tube was gone bad a while back for a KLOV member that was about 6 month or so ago but no the monitor wont even power on but the monit is the least of my worrys.

Non-Working Monitor 4:
19" Visual Displays Model# 1019
Ok this one im not sure of but im leaning more towards no ISO Cuz the monitor will not power on if in is hook up through an ISO. but when i hook i up without an ISO the games pictures will show up like i talked about above with the high voltage wave on the screen and this monitor is brand new so nothing should be wrong with it.
