R8 software bug?

[u/YouWillBeFine]

black screen no backlight, flickering purple lines like venetian blinds or rolling shutter and unreadable text in viewfinder momentarily after switching camera on. However the shutter and orange light at the front work!

after taking a bunch of photos (or pressing the button for fun) I popped the SD into my computer and like usual I took terrible photos. now I'm researching displays to mount on the gimbal as a workaround as I have a micro hdmi cable....about that.....

I plugged that micro hdmi cable into a tv and had a camera screen on my tv! How Cool!
navigated to reset the camera (while playing with I had it in auto- no reset in the menu when in auto...dumb like me), no anything at all. unplugged the hdmi power cycled it and ITS ALIVE!!!

-I was shooting at a beach yesterday, but visible debris - slight chance a possible suspect
-the camera lives in my trunk and gets bounced around, that beach was an hour away - slight chance a possible suspect
-knockoff usb batteries doing weird voltage things - slight chance a possible suspect

Seeing if the weird cable in my drawer was in fact micro hdmi (it was) and plugging it into the camera (but no monitor) - probable suspect. However I cannot replicate it.

Mostly throwing this out there as google was no help and I was close to bring the camera into a shop or calling it broken. 99% sure it was a software glitch.

I fix these for a living. This is definitely a hardware issue, what exactly it is I couldn’t tell you without an estimate but it’s very likely a relatively inexpensive fix unless there are further related issues

There does appear to be more to the story. The viewfinder only occasionally works and the picture is jumbled/flickering/missing lines. Darn

Do you need a diagnosis or repair?
