Squeak about the backlight on

Hello.
Help with this problem. After replacing the module, a squeak was heard from the motherboard side, when the backlight is on, there is no squeak without backlighting.
I sent a train from the broken module to the workshop, where I bought a new module and I was told that there were different audits on the line and, therefore, could be squeaking.
Is it threatening to use the module of another revision? In spite of the squeak of other defects, no.
Thank you.
