No, I'm sorry to say that the TV needs to check to find the problem. There is not way to just disengage the "protective mode".
If you would like to attempt to trouble shoot this yourself, you should obtain the service manual and with some electronic experince (maybe a friend) try to locate the problem. There is no one place we can direct you to with the information that you have given above.
You can obtain the manual by clicking on this - service manual
