Screenshot 2024-09-18 at 1.17.04 AM.pngI've tried everything I could possible think of in order to fix this, if anyone else has any expert advice I would greatly appreciate it. This issue has been going on for almost 2 weeks now. 

This was purchased 5 years ago at Best Buy. 

 

PLEASE READ BEFORE OFFERING ADVICE:

I removed all wires that were connected to my TV. 

Yes, I tried turning it on and off again. 

I tried to hard reset my TV by pressing and holding the power button. 

I left my TV unplugged for 48 hours.

I tried connecting my internet through an ethernet cable which obviously didn't work. 

I tried to reset the TV to factory settings by using the secret service menu and it got stuck on the Hospitality tab. 

I bought an antenna to try and scan channels.

I tried to do a software update via USB.

I was able to connect my gaming devices however the sound does not work and picture quality is horrible and heavily tinted green.

I tried to update it multiple times through the settings and it showed me weird symbols during and after the update.

Unfortunately the one part of the settings that would help me with this whole mess doesn't work. I get kicked off of the screen no matter how many times i've tried.

 

Please let me know if you've ever had this issue and now it was resolved. Purchasing a new television really isn't in my budget right now. Appreciate anything and anyone that can help!
