Matrix not working

Question

Electronics

There is an AUO b101aw02 v.3 matrix and an M.NT68676.2A controller, after assembling the circuit I apply a signal to the controller input via HDMI or D-sub from a laptop. There is only a white screen on the matrix, nothing else. I checked the LVDS cable, everything seems to be fine, everything is set up correctly. How can a malfunction be diagnosed? Or maybe someone came across and knows what could be.

Answer 1

Organizationally
In Moscow, this was done by Megalit in St. Petersburg Monolith Elcomm - you can talk to them.
Technically
, it looks like either a malfunction of the controller, or still problems with the connection. Diagnose. 1. as far as I remember they had remote controls, you call up the menu. If the menu is called up normally and shows perfectly, then there are problems with the LVDS connection. If the menu is not displayed, it means the controller is already (or its power supply, there have always been problems either with the capacitor or with the driver)
