Hi..

My dear Philips/Fluke PM3070 oscilloscope has a problem.

Normally it stores the values of the voltage scales, time scale and other
things when i switch the PM3070 off.
When i switch the pm3070 on again the settings are restored.

But since a few days the settings are not restored.
The PM3070 now starts up with no A and B channel visable.
I have to push on AUTO SET to get them back.
Then every thing seems to work again.

Fluke told me in some PM3070's are two penlights batteries inside.
But i do not see them.
And i can not see any other battery.
Here are several pictures of the inside

What could be the problem ?
How to solve it ?

Thank you very much.
