Samsung NX1, 4K recording errors

[Pavel D Prichystal]

Hi, 

it looks like my NX1 partially gave up after less then two years. Wierd thing is that problem occurs only in all 4k/UHD recording modes, other modes are totally fine and its perfectly fine with pictures also. Here is link to see how it looks like. Bars across most of the screen every 3rd frame. 120FPS, 50FPS and other modes are completely fine.

Any suggestion what should I try to fix it before sending it to repair? I tried formatting SD cards, factory reset, and FW downgrade. Maybe something in DEV mode?
Btw I WAS using Vasile's hack for some time now and when recording 4k (with the bars now), after a few sec - few minutes it crashes showing "SD card Error" warning.

That's a bummer man, sorry to hear about the errors. Hopefully it wasn't caused at all by the hack. I'm running vasile's 5.11 with the on wake mod. Which version are you on? Also did you try different brand sd cards?

This is very weird, as I do not comprehend why it happens only in 4K mode and not in everything else?

Currently I am not using any of the higher bitrates, as I am not certain how bad the excessive heat is for the sensor, and for what I do I prefer lower Giga bytes and reliability than a bit more of bitrate.

Where are you sending the camera for repairs? Do you still have any kind of warranty?

I hope for the best.

Any effect when using lower bitrate, different frame rate (30p, 1,5p), PAL/NTSC, distortion correction ON/OFF (works also in video mode but only with Samsung lenses)? I do not know... I am just guessing.
