When I power up the tv by remote or using the depressing the power button located on the front of the tv, nothing happens. What shows is a red light, then i hear the sound it is going to come on and then a click with a red blink, this will happen 4 times and then it will repeat this same action. No picture / No sound. Is there a reset button on the set? Or do I take it to be repaired? Can anyone help or explain what I can do. Thank you
