Hello & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) Can you still reach the DISPLAY settings, and ADJUST (change) the brightness of the display?
Please use the REPLY box below.
Hi again and thanks for that information.
OK - as long as the brightness CAN be adjusted, that is a "good thing".
So to answer your original question, this symptom COULD be an issue cause DURING the repair of the USB connector - and MAY be as simple as a loose or misaligned "ribbon cable" - that connects to the display.
If you receive ANY kind of "warranty" on the repair, I would take the device back to the place of repair and have them CHECK their work, and the connections of ALL ribbon cables - to see if this issue can be fixed.
As a reference only, I have a couple of links to videos, that show where these ribbon cables and connectors are located.

Of course if you are good with your hands, you could check these connections yourself - or with the help of a friend. This assumes you have the tools to open the case AND that the repair place would charge you more to investigate these symptoms.
Please let me know what you find or if you have any more questions.
