Kapta Security DVR repair
« on: May 15, 2023, 12:06:08 pm »
Hi all,

long time lurker, first time poster.

I am trying to diagnose and repair a security camera DVR box, this one labelled a Kepta 1116.

Problem:

- Short beep to signal its powering on
- Nothing follows for 1second(ish)
- Short beep to signal its powering on again

I was looking at the power supply side of the PCB, like there might be a short circuit which causes a reset, then repeat, but all the caps and diodes look good. I've removed caps C203 & 2C207, but that seemed to only change the tone of the beep.

Ideas on where I should probe next?
