BK 2553 Oscilloscope Power Switch Problem

[Henry Finley]

The power button on the front panel lower left on my BK 2553 scope has a problem. I have to press it multiple times before it finally "catches" and turns on the scope. I keep pressing it and the displays blink briefly, but won't stay on. I have to keep pressing until I'm lucky enough for the displays to blink on and STAY on. I have pretty much of an equally difficult time turning it off. This has nothing to do with the master power switch on the back. We're talking about  the so-called "soft touch" switch on the front, which is not so "soft touch" any more. Thank you.

You might be able to get a replacement membrane from Siglent NA as this BK model is a SDS1000CFL rebrand.

Does anybody have an idea about when my BK 2553 was made?
