Model no LE040A656A1FXU
The TV is about 7 years old and the problem started this morning

Thanks Eric for the info.
It is 40 inch Samsung LCD TV, this kind of problem occurs due to defective power supply board or the main processor board, mostly the power supply board found bad and swapping it will help to resolve the issue.
Required power supply board would be available at ebay around 30 Pounds, please check following link for details..
Local TV repairman will replace the power supply board in TV if you are not comfortable doing so by yourself, I trust my input will help you out. Please feel free to respond if you have any additional questions.
