Checking the flex communication from the main to the tcom if it is well check that the tcom is properly fed
these are the voltages from the main to the tcom

In my opinion, if you have the voltages, that's why I need the diagram to see if they are okay, but I can't.
what else could be the tcom card or the matrix card of the display?
there was a fuse with the fuse next to the connector that comes from the main and please measure what voltage is in this
if you have a friend, all the tcon have a smd type fuse, locate a resistance similar to the connector near the serigraphy F1 OR TALVER RF1 ORY ON THE LABEL OF THIS SAY 0 OR A NUMBER AND A LETTER TO EXAMPLE 5A
If they appear wrong your panel carefully check the flexes that are stuck on the screen
Check the flex of the coff chip as I comment all the voltages appear when disconnecting the display is that there is this problem can help in what they sound specifically friend
