Default Philips PM3262 Oscope Failure Help needed

I picked up a Philips PM3262 Oscope at my town's recycling center. it
looks like it has been well used.

I plugged it in and turned it on. It worked normally for about 2 minutes
and then shut down. The ckt breaker on it did not pop. The "ON" light
was off. After I let it sit for a while, this repeated.

I don't have schematics and when I took the covers off I did not see
anything obviously out of kilter.

Has anyone had this problem and fixed it easily? If so, could you post
the fix?

Thanks in advance.

Had a similar problem with a Philips PM scope.
Turned out to be the high voltage transformer shorted a turn
after it warmed up. I rewound the thing...yeah, that was an ordeal.
Worked for a few days and shorted out again.
