Not so happy birthday

So far, DH is not having a very good birthday. His beloved 9 year old big screen tv has lost it's picture! He kept banging on the top, and it finally came back on, but when he turns it off, it's gone again. He's at work right now, and I've banged and banged but no picture. I guess after 9 years, it's needing some work. We have other tv's to watch, but his big screen is the one he always goes to for watching movies, and he likes to watch a movie almost every night. Right now, his favorites are "Fireproof", "Facing the Giants", and "Flywheel". They are all inspirational movies and really, really good. We'll be having DH's family birthday party on Sunday, so hopefully, we'll have it fixed by then. The grandsons (9, 6 and 4) like to play games on the big screen. They'll be very disappointed if it's not working. I'm going to go and try banging again. Wish me luck!
