Have TV Questions? Ask a TV Technician
Hi Ron and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the TV.
Appreciate the additional information.
Let's try review/check the basics...
Is the Sharp completely/electrically dead? ...or is there some indication of power such as a standby LED light? ...or even blinking?
Have you tried unplugging for an extended period of time? ...and then plugging back in using a different outlet?
