Olevia 32" LCD HD TV model 232-S13

Question

I just purchased this Olevia brand 32" LCD HDTV. Only 8 days using it and tonight I turn it on and there is no picture image but just sound. It is not black but it is dark blue. Called Olevia support but there was no help. They took my information and will contact me in the future. Why there isn't no picture just sound? in a brand new TV. Please give me a suggestion.
