DVR problem (lines, flickering?)

[Fotis]

Hello,

I have a DVR with Hi3520.

I have this problem.


Has anyone any though why is that?
Reset settings, change cmos battery, change power supply tried.

Maybe your monitor is crapping out. Try a different monitor. If the result is the same then the video controller chip in your DVR/NVR is crapping out.
