RNS510 not booting

**kostelectronics** · 1st August, 2023, 11:53 AM

Hello all,

I have a RNS510 to repair. It does not even try to boot, current is only 11mA after connecting to the PSU and it stays there. After few minutes, the current goes back to 0mA. When i press the power button, it goes up to 11mA again. It looks that the ST10 does something (maybe inital bootloader) and then nothing more. Does anybody have a good idea what to check next?

Hi
It might be a problem with a short on the board. It might be drawing current and shutting down because of some short on the board.
