It is the internal mainboard that has faulted, this is not related to the software, this confirms it
I am really sorry about this and you are going to have to return the Sony 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.
