Well first of all it could be a pcb issue so bare with me. The exact model is 25k7190 with a Zenith tube. Both the pcb and monitor get the correct power. The game is also jamma Konami Racin Force. The monitor doesn't turn on and I hear no sounds from the speakers
. First I checked the power and both are correct. The marquee light and coin door lights both light up also. I checked the fuse on the monitor it was blown so I replaced it fired it up and it blew again. Is there a fuse on the board because I couldn't find one? I noticed when i was checking the volts from the jamma connector that pin 4, on the parts side, was getting hot very fast seamed like it could be shorting. That wire only runs from the power supply. I took the connector off and the board has a nail tip size burn on the pin.
Any troubled areas I should start? I read that the flyback and/or hot could be bad but the board keeps me wondering.
Update: Thanks to Cadillacman's sticky I checked the flyback and noticed it has a hairline crack and looks like its fryed in the middle. Would this cause the monitor to be dead?
