BCS-DVR1601MEA Recorder: No Picture, Swollen Capacitor Replaced, LED & Voltage Issues

After connecting, the power LED and the LED on the motherboard are on, but there is no image on VGA and HDMI.
The voltage on the board is 12V, 5V, 3.3V and 1.6V, 1 capacitor was swollen, but I replaced them all.
From time to time, the recorder must be reset because the fan and disk stop for a short while and then turn back on.
The manufacturer's website is soft Link
There are 2 ways to upload the software, one is from a pendrive but it rather falls off because you have to do it from the recorder menu, the other way is via LAN only that the recorder does not receive an IP address.
There is MX25l12845E memory on the disc, does anyone have a batch from it?

Hello, I have the same problem with the BCS-1604LE-AS
every now and then reboots no vision, all buttons on the panel and on the remote control are inactive.
Two LEDs on the motherboard are lit and one is green
but the other one next to the battery is red
what else puzzles me is the lack of a characteristic bios sound at startup.

Hello, did you manage to settle something with these recorders, because I have the same problem.
