No, thats the electronic switch on the main board
This is the problem It is the mainboard that has faulted.
A corrupted firmware can cause this. But we have ruled this out by trying to hard restart it.
I am really sorry about this and you are going to have to return the TV to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
Thank you
