Thanks for the reply
Here is some more of the story. I bought a sky shark cab with a bad monitor. It is a Jamma board so I just plugged it into another jamma cab I have and it comes on and says.
Ram check ok
Rom check 19 error
I have tried other jamma board this way just to test them in the past and it has worked.
I have not reseated any I.C.'s. I have a friend who recommended the same and said he could help out. (since I have never done it.)
The board does look very clean I went over it in some detail last night.
