The screen is about $170 in the US [URL] You can use the part number to search locally. The system does not have a separate TPM chip, but the processor you have (10th gen) supports Intel PTT, which is functionally the same thing.  It is enabled as described here: [URL] This assumes the system was sold in a part of the world where TPM/PTT is allowed (it is not permitted in China, Russia and other parts of the world).    
At first when display was set to 120Hz, it froze from time to time with some black horizontal lines. Now the laptop is incapable of operating at 120Hz, whenever I change from 60Hz to 120Hz, screen turns black and then it automatically reverts back to 60Hz. When connecting to a wireless display (smart TV) it can operate at 120Hz but still the laptop screen turns black yet everything is running smoothly on the TV screen. I suspect it's a problem with the display itself and not the video card GPU. Please confirm and provide the price in EGP of the hardware to be replaced. Also, I need to know if the laptop supports TPM 2.0 and whether the hardware is already installed and just needs activating or if I need to buy it? If there's a workaround to install Windows 11 without TPM 2.0, kindly provide it.
