Wifi Greyed out and bluetooth

Hello, I got this phone in repair today it had already had the screen replaced on it before working on it the screen was an Aftermarket LCD not OLED I am thinking that the screen shorted out the board causing the wifi not to work anymore. Anyways I tried a new antenna and still greyed out anyone fixes this issue or know what I should do next or is it SOL?

is the WIFI not working since it crashed? If so, it could be a problem with the motherboard. You have to separate the motherboard first. maybe the pin is disconnected

Check it’s on the latest update. Also if there is a security app on the phone remove it. I had a phone in with the same issue. They had some security app that had disabled the connections, when I removed it all the connections came back on straight away. If it needs updated you’ll need to hook it up to a computer.

Most likely cracked or torn pads on the interposer board or the Wi-Fi IC. You will need to separate the boards and check the pads between the boards before taking diode measurements of the Wi-Fi IC.
