Batboard

I have a service monitor that recently started going through a loop of bootup. It has gotten to the point . Its not usable right now.

Any one seen this before ?

Did you sorted it out ?

It looks like a short from Power supply unit that is usually cause by bad CRT flyback.

Try disconnecting both power and data going to crt board. You will not get display but will be able with beep sound to tell if still reboots.

Also did you changed/removed any option boards at the back ?
