Hi,Thank you for using Just Answer my name is ***** ***** I will help with your question.I am afraid to say it could be a number of things that could cause that fault, Does the tv click at all?
Would you look at repairing the set yourself?
It is likely that it could be the power supply some samsungs suffer from bad capacitors your model does have a problem with capacitors but that may not be the problem.I am able to suggest a tv repairer in your area if you send me your postcode?
I am afraid that it is not likely to come back to life without repair. Have you had any trouble before like slow startup or random turning off?
I dont think samsung do cover it, It would be good if they did as it was poor capacitors that cause the problems but many capacitors fail a few years outside warranty.

That is a copy of the advert on the forum.
Many engineers will charge an inspection charge for looking at plasma tv as they can be time consuming
