Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF OLED Blank screen

[Kalman27]

We have a Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF for repair. The original issue the OLED screen is blank.

We have replaced the OLED screen with the exact model, also we replaced the LCD cable, but no luck.

I think there is something with the motherboard. I don't really have experience with OLED screens so far, so not sure how it should work. I have seen some laptop comes with a separate controller board, but this model does not.

Also, there is an error in Windows device manager - This device cannot start (Code 10) - Intel(R) Serial IO I2C Host Controller - 51E8

If somebody could point me the right direction, that would be great.

Attached a photos of the motherboard.

Error code 10 is often due to 'not enough resources' or similar fault with the device driver installation. Suggest to hunt for an Intel chipset driver package to pacify the missing I2C device driver for this hardware function. The same I2C interface may very well be linked to the display control, etc. for your display. Once you have a valid installed driver for the I2C interface, test again for your display.

Thank you, will give it a go and see.

I have tried all the possible drivers, but there's no luck.

Now I strongly believe there is something wrong with the board itself.

Can someone advise me on what to look for on the motherboard, please?

Many thanks
