Welcome to JustAnswer
I will need the model number first please found on the back?
Is it just the power LED blinking or is the opc LED blinking too?
The model no. is LC32SB23U. It is just the power LED blinking.
Its my guess the firmware has collapsed
Their is little you can do Im afraid
The firmware will have to be re-loaded or upgraded on your board or the mainboard replaced firmware pre-installed
The above link is generic to all sharps made over the last 2 years and give pointers as to what area of the set the fault may be.It sin my experience 75% of the time its firmware issues
You need to ring Sharp
Im sorry it wasnt something easier
If you have questions please ask
It can be especially if the board is replaced sometimes $400+ it would depend on the strategy of the repair company sharp agent
Another may redo the firmware on your board that would be cheaper (assuming the board can be saved)
A home visit has costs built in so you would be better off if you can taking it into an approved agent.Its only an approved agent that can do the work.
