Hi TobiasTV, you gave me a great clue where to continue, I also noticed the same thing, the two boards are exactly the same model but the difference is that the one I got from replacement has a few extra components, it would be understandable if the board offered an extra function How to be the 3D function. I already put it under a magnifying glass. Thank you, friend!
As the partner says, you have inverted the Vesa / Jeida pin. you have to look for the panel or tecom datasheet and in a datasheet it will show you the 31 or more pins and what function each one fulfills. or simply when you find the pin vesa / jeida, measure it with the tester and if it doesn't have 3.3v send it to ground. before doing that, unlink the main pin (from the flex that goes from the main to the tecom) or directly from the tecom.
Good luck and regards.
This is how Pantrizte is a colleague, it has already been replaced, both the eeprom and the nandflash (moved from the old main to the new one), same processor board itself, should have raised the system correctly. I already upload a photo with the replacement. I am analyzing the possibility of replacing the main again, but it is giving up very quickly, the solution may be in sight but my head is already exploding .. haha
