I am new to this and have worked on this for 3 months, so if I sound a bit slow, please teach me.
I have bought a Samsung TV with a One Connect box, basically a unit that has electronics, connections (HDMI….) and the power supply you can place away from the TV and connect with one cable. Unfortunately, the box (I believe the power supply) starts making 2 different high pitch noises in 2 different situations. I make recordings, which is very difficult. I just can’t catch the full effect of the sound with my mobile phone or tablet. Perhaps it is the microphone or the speakers that can’t handle high pitched noises.
I now contact Samsung who agrees there is an issue and can hear the noise on my recording. Suddenly after some time they decided that there is no noise. Months later and much busy work and demands (resets, tests, videos not only audio) from Samsung I am trying to make a video with visual evidence of the high-pitched noise.
Method:
Samsung Galaxy Tab S5e with Sound Analyzer Pro app installed. (Tablet)
Samsung Galaxy S9 to make a video of the Sound Analyzer app on the tablet. (Mobile phone)
Situation 1: (Not a problem, just used the quite sound as a test)
When the TV is on, it makes a high-pitched noise from the power supply, so low that to hear it I must put ear right next to the One Connect box.
I put the tablet next to the box and start the app. Clear sound spikes at 3266,4 Hz and 6532,7 Hz, and they disappear when I turn off the TV. So, I am happy, it does the same thing with other sounds too, and now I am thinking my method works.

Situation 2: (The real problem, I complaining to Samsung about)
Sometimes the box makes a loud pitched noise, unfortunately it is periodically, and takes a long time to “catch it” happening. I can clearly hear it from 4 meters away, so the frequency must be in the audible rang, 20Hz – 20K Hz.
It is much louder than in situation 1, and therefore it is easy to see in the Analyzer app, but NO NOTHING.

I just don’t understand. Is my method wrong? Is my equipment just bad? Have I misunderstood this on a fundamental level?
Any advice? Or comments?
