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.

Assuming you are using the internal speakers, check and make sure you have the audio enabled. Some TV sets have a option to turn off the internal speakers. Also make sure mute isn't turned on. If you are using external audio setup, double check your connections.

Lc-40e67un sharp aquos. Power light is blinking in a constant rhythm with no variation. I tried the volume - and input reset. I saw a flash of the channel number and a gray screen for 1 second. Went right...


How many times do this standby light blinks at one time switch On? Count it carefully. These are called blinking codes, and from the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. If you wish to get more details about these blinking codes, check this link.http://electronicshelponline.blogspot.com/

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.

Television is not recognizing HDMI inputs


there is a possibility that there might have been a power surge sent over hdmi into the hdmi board on the tv. if on your model the hdmi board is seperate from the sine board then youll have a cheap replacement if not its gonna cost you roughly 300-400 is my guess.

call your repair guy

Have DVI cable plugged in how do i get audio


There should be a HDMI input on the Sharp Aquos with audio inputs next to it. Run a audio cable from the audio out of the satellite box to that audio in next to the HDMI input.
I hope this helps,
