H Carolyn,

May I know the exact model of your sharp tv? theres a sticker at the back of the tv and you will see the model from there.

You can send me a reply by entering your message in the box at the top then hit the send response button to send.

Ok. I'll wait here. 

ok. hold on

thank you for waiting.

do you see a light indicator when you turn on the tv set? 

there should be a red standby light at the bottom bezel although the tv is not turned on but plugged in to the wall outlet. 

Heres the location of the power indicator. 

Do you see the Sharp logo on the bezel of the TV? The power indicator is usually below it and all sharp tv has that little red light indicator. 

do you have a cellphone number that I can call? 

Ok. I will your phone. Please do not close this chat page.
