Hi to all in the group.

I am new to the group and I want a help if anyone can.

I have the E4418B in a perfect working condition with one exception in the Power on sw.

It is not working at all and the instrument is always on .

It is not bothering me because I am closing the master sw in my bench , but I want to fix it if I can.

I have the 2 service manuals that I can find in the web , but no one has any schematic diagram nor any info about this problem.

I appreciate any info about this problem of mine.

?

Thank you all.

Nick
