Hi everyone!

I have an older model Toshiba television, model 42AV500U, which I haven't used in the last year. Today I tried to set it back up again, but when I went to turn it on, the light in front turned green, but no picture or sound resulted. Does anyone know if this is a common issue with televisions that have been out of use? I'm worried that it's just bitten the dust, I hope that someone with more knowledge than me might be able to enlighten me a little though!

Thanks very much for reading, and for your help!
Cheers

EDIT: It seems to have fixed itself! I left it on for a few hours to see if maybe it needed to warm up or something, and it just started working again! I don't know how to delete my post, so I just wanted to put this edit out there. Thanks a lot!
