Any idea what is this??

I have been buying computers and monitors since 1996. I always give my old monitors as a gift to someone else when i buy a new one. This is the first time ever i had a monitor DEAD in 7 months!!! Was working perfectly well since February 2019. Yesterday, all was fine. I had a short nap and woke up with this. It is not related to PC. Even if not connected to PC, once you turn it on, you get these lines and colors. You can’t do or see anything. I guess it is dead. I have no option to return. Any one thinks anything can be done to fix it? I will end up buying a new monitor. It was doing very well while functional to be honest but i never expected it will die in 7 months of light use.
