polo2 monitor test

[G1zm0]

i have a old golen tee cab, monitor was working perfect before i stripped it to incorporate mame, ive not had it on since feb 08, ive no board to test it.

is there a way like a test switch i can use to make sure it works ok --BINGO! Either that, or I was attempting to say "before" but it was too many letters to type-- i continue with the project ?

its a polo2 monitor...
