EVF live and current playback is very wiggly
I just bought a Panasonic PV-420D VHS camcorder and off that bat the EVF is extremely wiggly and when it records to tape it records the wiggling too. I am using a VHS that was originally in a VCR till 2003 but when I playback the recording the viewfinder looks completely fine, even when I recorded the new footage over existing ones it was only wiggling on the playback of the new footage. I’ve tried it with the new battery and plugged into the wall. The only thing that makes it go away is lower light, in the video I turn on high shutter speed and it goes away completely, same for if I’m in a dimly lit room. Any help on what is going on here would be greatly appreciated!
First photo is the wiggling, second is with high speed shutter turned on, third is playback being normal
