Question Vizio V705-J03 TV Repair Question

Jan 30, 2023
I have been searching around for an answer to this and can't find it. My Vizio is out of warranty and has basically vertical lines and shadows. I purchased a new TCON board but it seems this TV doesn't have one. Not sure if I should purchase a new main board and/or new power supply board for serial # LFTGD7KX .
