Model ? Few years old.....gone pop?

Typical that whhen my hubby goes away my TV decided to go, the screen went black with a white flash initially and no sound. The standby light is on, however when I try to switch it on, I can hear a ticking noise from inside and after around 5 secs it goes back to standby, hope someone can help. it's our only TV and the kids are already driving me nuts during these school hols!

Anna
