Hi everyone, I wanted to ask for an opinion, I have 2 identical monitors, only the firmware and serial numbers change, 1 has a faulty card, the other I should put the firmware and serial number of the faulty card in the other working one, in the photo there are 2 eproms, the one on the bottom left of the processor and the one on the top right, I changed them, but nothing has changed, do you think I can do other tests?
Thanks to everyone

What you changed is spi flash (25 series), look also on the eeprom board or take a high-quality photo of the board on both sides so that you can see all the chips.

I hope it's clear enough, I swapped the two Winbonds but nothing, I have doubts about the MXIC chip

That's it, there's nothing visible, I asked you to take a high-quality photo in high resolution.

Sorry, this is

It's hard to see in the first photo, but in the second it's not that, it's a temperature sensor.
