I changed the LCD only. The brightness setting does not work.

only ON or OFF, no brightness adjustment.

Do you know where the error is?

I’m thinking the cable may have been damaged. Multiple pins carry the backlight power. Otherwise the logic board backlight control has an issue.

Why did you replace the display? If this was a liquid damaged system the connectors or cable could be corroded as well.

Take a few pics of the connector and cable ends so we can see what they look like iFixitでの質問に画像を追加する方法
