HANTEK DSO5102P boot up issue

[Krf1786]

Hello!

When I turn it on, the screen stays black and the buttons on the right side start flashing and it makes a ticking sound when doing so. This just continues until I turn it off. It was working fine, sat in the box for a few months, then when I turned it on recently, this happened.

I emailed Hantek and they asked me to check the input voltage. The 5v and 3.3v. I got 4.7v and 3.3v. I responded to them and still haven’t heard back in over a week. Hopefully someone might have an idea of what this issue could be! Thank you!

Does the voltage on the PSU stay consistent, or does it hiccup? Hantek's assumption was correct. These symptoms indicate a hiccuping PSU.

I did not see any fluctuation
