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: Problem connecting my PS3 to my Sharp Aquos LC-C3237U LCD TV

Your PS3 set itself above the max resolution your LC-C3237U. Most likely the PS3 is doing 1080P, but the highest the Sharp can do is 1080i. So do this:

1. Connect PS3 to TV (you can use the current cable or analog cable)
2. Turn on TV and set input to port PS3 is on.
3. Make sure PS3 is connected via correct cable.
4. Power on PS3 via power button and HOLD IT for 5 seconds (release after the second beep). It should automatically configure your PS3 to the TV's native resolution for all settings.

My sharp aquos 37


If it's the LC-37G4U model, double check the System Cable that links the TV to the box. Then, open the front cover of the box; with the TV ON, press the small SYSTEM RESET below the INPUT 3 port.
Let me know if this solution works.

HDMI connection problem


Your TV doesn't like your laptop I guess.
There should be 2 reset buttons behind your TV.
Press the reset button first.
If that doesn't work, try the system reset button next.
If that doesn't work, you'll have to call 1-800-BE-SHARP to help you with the possible software problem with the TV
Good Luck
