I still have the original equipment audit monitor.
The screen lights up so it has power, but nothing is displayed. Any ideas.
Thanks
I replaced mine with a flat-screen LCD monitor. They are widely available (on Amazon and various other sites) and are easy to adapt electrically. I mounted mine on the front of the panel over the hole left by the original and fabricated a small aluminum plate to go behind the panel to which the new monitor can attach. If you have the luminescent dash be careful not to drill holes in it.
Not sure if these will help, but the Javalina/Audit docs are in the Media section

I did as David and then changed out my camera as well. You will have a BNC connection to the original monitor, you will need a BNC to RCA adapter for the new monitor. With an adapter you could test drive your system by running it to the composite input of TV. If the Audit system has died, then the Seelevel upgrade makes sense.
