No signal, no connection indicator in webui

[cenedek]

My diy gbs-c that i have just built, is not working.

It is a v5.2 board with Nodemcu v2
Checked connections, theyre all fine. Nodemcu gets 5.5v too

There is no video output at all.

It is hard to get into the webui, then it always shows that there is no connection. I can't change any settings, only switching between AP and Wifi mode works.
The nodemcu's blue led tends to light up after some minutes of operating and it stays lit for some time

I posted this in gbs c scaler facebook group, and another person also has this issue.

.

Any advice?
