I have a Sanwa 27Z21C-A74A monitor I am putting a new flyback on, as the old one got a crack in it and it was leaking high voltage. On power up it arcs out and blows the main chassis fuse.
The question is, I found a new flyback and obtained it from Russel Industries, and I want to install it, but I found some scorching under the old fly back. I don't want to have the new one fry, so I figured I would see if anyone has any pointers on things to check before I replace the flyback and power this chassis up again.
I have done board repairs before, but I have never had anyone experienced to work with and learn from
, so I am just looking for advice and pointers. I would greatly appreciate any help or input
.
I cannot LCD swap this machine as it uses light guns, being Time Crisis 3.
I apologize in advance if this is a bit spammy with the pictures.
Pictures as follows.
