Hi there. My dso scope is way too noisy unless I can bend it with my hands at a particular angle. I've been trying to find what component is lose but I canot find anything. I was very meticulous and soldered everything very carefully and all the smd components look ok. Below is the screenshot of what it looks like without me bending it. Does anybody have any idea what components might be causing this or how I can fix it?
Thanks!

Edit: all the voltages are fine and the variable caps don't seem to make any difference to the noise.
