Philips PM3262 Oscope Failure Help needed

Apr 08, 2007 3 Replies

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. mike

Had one of these as a bench 'scope back in the day. Most of the internal voltages come from a switch mode power supply which will fail as you describe at the slightest provocation. Tough to fix without circuit diagrams and you will need a 'scope that works.....

From the responses I've gotten, it's best for me to take it back ;-)
