Hello my name is***** look forward to assisting and am very sorry to hear that you are having this problem.
I want to warn you that it is possible you will need to replace a part in order to fix this.
There are a few different things that can cause this and a couple different parts so we would need to troubleshoot to find out for sure.

Darn it is no longer under warranty then. I really hate to tell you this but U81 is normally caused by a blown capicitor on the board. If you have ever soldered before you can usually see it. It is a C153. If you have never soldered before you may want to bring it to a shop if done improperly you can damage the entire board. IC1508 normally needs to be replaced as well. If you have any questions at all click on reply to expert and let me know. If not please don’t forget to leave a positive rating for my help - it is greatly appreciated. Please note you are rating me only not this site or your Panasonic.
