Weeping Cherry trees: weeping cherry tree and lilac apear to be dead?

» lucia52 - weeping cherry tree and lilac apear to be dead?

I planted a weeping cherry tree last year at the end of April having lots of flowers. The tree was accurately planted, it is in a sunny location, watered normal. This year after all the trees around started to show their buds I started to worry because mine seems to be dead. The appearance of the tree is ok but there is no sign of life, no buds and I am not sure if this means the tree is dead, should I wait or I should do something. I tried to trim the branches to see how they look, some of them were brown and I cut those shorter but other seemed ok to me.
I have the same issue with a lilac planted same time last year in the tree proximity.
I need an advice
