After pressing the power button or the remote button, I measure the source output voltages:
two 5V outputs
two 24V outputs
a 12V output
and they have those voltages seemingly correctly

If you do not have to record memory, another thing that you can try although you rarely see it works .... there is a connector with 3 legs on the main board, connect the middle leg with the top with a screwdriver and connect the TV for about 10 seconds you take out the screwdriver .... if it does not start, do the same with the middle and bottom legs.

Try what I told you ... and if it doesn't work you have to record the memory with a Flash memory recorder connected to the computer ... if you don't have a technician I recorded it ... or someone I fixed computers you take the file I send you and the memory ..

I tried the short of two connector legs and it didn't work
I interpret that the memory is recorded through the 3-pin connector? because in the platelet I don't see any integrated that can be removed, they are all welded
