first post here as I got a new Picade and trying to exchange the screen to the Samsung Screen 12.1" LTN121XL01-N03. So I bought the LTN121XL01-N03, a fitting controller board and a 12V 4.16A power supply. Unfortunately no matter what I connect via HDMI or DVI the screen stays black.
I suppose the controller board is working because the LED on the button panel is red when power is connected and becomes green when HDMI is connected. I think also the display is the issue as even when I push the “MENU” button on the button panel, nothing appears on the screen.
But right now I’m still unsure who to blame. The screen and the controller board came from China and it would be expensive to send it back. So I had the idea to ask in this forum if anyone in Germany or even the EU is actually using this screen. I’m thinking of sending my screen and controller board to a user with a working combination to find out for real what is the problem.
Of course I would cover the shipping costs. If anyone has another idea what I can do for testing I’m happy to hear.
