Why is the left side of my screen dark?

I recently had problems with my iphone’s vibration. It was buzzing strangely whenever something vibrated (ex. The home button or a notification.) I decided to look online for a fix. I took off the screen, tightened the screws for the “Taptic” box (to the left of the home button) and put the screen back on. The weird buzzing is gone but now the left side of my iPhone screen is dark. Please keep in mind I am very inexperienced with iPhones and don’t know very much about the inside of the phone.

ps. The darkness is in sort of a crescent shape (if that helps)

It’s very important to always disconnect the battery before disconnecting/reconnecting the screen assembly. The issue is that the LCD connector has pins that have high voltages (i.e. the backlight is ~20V) and ground in very close proximity. When you fumble around trying to line up the connector plug to the receptacle, you can short out the voltage rail and cause damage to the components in the backlight circuit. If you’re lucky, then only a backlight filter is damaged (there are tow, one for each half of the screen) but other times, the entire circuit could be affected. Either way, this type of repair requires micro-soldering and isn’t really a DIY repair.

I wish I'd been aware of this preventive, cautionary step BEFORE I had one side of my screen go dark. Do you know what the fix is? Is it expensive?
