ZV-E1 SD Card play back error

[om5]

when entered into playback to view a video you just recorded, you are greeted with "playback error" message.

then your machine will be able to switch back to recording mode, but nothing will be written into the memory card.

turn on/ off fixes the issue, but sometimes require battery to be taken out because the ON/Off button sometimes be unresponsive after the playback error.

I took the camera in for warranty repair, but the technician said he wasn't able to replicate the problem.

 

I ran into this issue pretty frequently, on average 2-3 times a shoot. just wondering if this is an issue with my camera, and if any other experiencing the same issue?

camera was not overheating at all, only recording 1-3 mins b-rolls, camera body is cool to the touch. 

camera has the V1.10 firmware at the time of the issues.

format I was shooting: XAVC S HD 60P 422 10bit 

memory card that I'm using:

it's been tested, no bad sectors in the card. V60. Lexar 1667x

 

on another note, my HDMI port seems loose, you can even wiggle it with the finger. it connects and display monitors properly.

are your ZV-E1 HDMI port behaves the same way? on my A7IV is solid, the technician told me it's normal.

i thought i should just add that into the list, because it connects to the mainboard, maybe have something to do with the issues?
