If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

SOURCE: I have a Sharp AQUOS LC-19SB14U 19' LCD TV that won't power on

The main power transistor in the power supply appears to have failed. It has also blown the fuse. Not a job for the DIY'er unless you have serious electronics experience.

I had the same problem with a Sharp Aquos 40". Sound just for a second and the message all the time in the middle of the screen, no more sound.
I opened the TV and found a speaker cable (a black one) with the PVC isolation broken and the wire in contact with the chassis. I just isolated it, the sound came back and no more error message.

The flashes are an error code. Count them till they repeat. Get a service manual and look up the error code. Some error codes prevent the set from powering up to prevent more damage. You can reset the code for troubleshooting. Repair as required.
