Hello friends! It turns out that I have to change the original plate of the Split 3000 LUFT refrigerators model LT-FS3000 and apparently the display broke and I cannot change the degrees because it does not receive the message from the control. The control works well. The thing is that when trying to replace the platelet with a universal one, I realized that I don't know what connects to those terminals that are inside the yellow circle. If someone can guide me I would be very grateful. The biggest problem arises in the upper pins because they are connectors or terminals that the original board does not have and I do not know what connects to those pins. The others believe that by guiding me on the scheme of the circuit of the universal platelet I can solve it but those pins I cannot or cannot see the solution. Above you can see from left to right the Universal Plate with the only connections that I am sure are going. But at the same time you can see the Original plate. This is the Universal circuit board circuit
