The usual culprits would rather be the ground clip itself or accidentally shorting something with it, more so than ESD. And if something has actually broken on the scope, I'd suspect the probe to be broken before anything else.
First try to calibrate the probe by hooking the ground clip to the metal terminal (bracket? I might be using the wrong English term) in the far lower right corner of the scope, then the probe to the terminal just above it. You should be looking at a perfect square wave - if not, then tune the probe until you do by using a small screwdriver. This is done by twisting a small screw on the probe itself - assuming these are probes with a square-shaped filter next to the connector, you'll find the screw of the opposite side of the text and Rigol logo.
After that, you can try to calibrate the zero offset through CH1 etc buttons then pick "delay cal" and turn the menu/intensity knob. You should notice a difference here or something might be broken indeed.

Finally, I've got some experience of using both the very model you mention as well as one of it's bigger brothers. These are _not_ high quality products. Expect random errors to happen, there's a reason they are one of the cheapest brands on the market.
