Default Help with LCR meter HP 4265B


I have an old HP universal bridge 4265B LCR meter that was given to me for free. It was working well in the beginning, I was doing measures alright - chokes, caps, resistances. I didn't power it on since a year. Now, it doesn't want to measure anything at all.

Click the image to open in full size.

I test it with known values of components, but neither R, C or L does measure correctly. The oscillation arrow doesn't stop at all.
May you guys give any advice? It doesn't look very complicated when I opened it inside.

It's possible it has dirty contacts/switch problems as any older stuff, or if it runs on battery check that, some of these older units ran on AC and Battery.
That is a nice older unit by HP.

Lots of Kenwood, Pioneer, and Infinity stuff.
