I have a TCL TV that under Settings - System has no menu for either Time or Power. Thus the user has no way to change the time. My TV is showing a time off by 7 hours exactly which leads me to believe it is set for GMT with no way to switch to EST, or any other time zone. I tried doing the 'secret menu' software upgrade twice with no result and the software is up to date. Chatting with customer support has so far yeilded no fix but he is checking with his team members for any ideas. How does the TV set the time in the first place and how can it be corrected to the correct time zone?
