The TV is on protect mode. This happens when an internal fault is detected. When a fault is detected the protection circuit prevents the TV from starting , the clicking sound is the protection switch that keeps turning off the TV.
Sometimes protection is triggered by an incorrect voltage, or electrostatic charges accumulating on the TV PSU capacitors. In that case the problem is temporary, and will disappear leaving tv unplugged for some times. More often, when tv goes on protect there is an internal fault that must be fixed.

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

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

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

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 , startingthe flashing light.


If you are in situation one, then theTV 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.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


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.

TV not turning on blinking powerlight with corresponding clicking


Zenith2.gif "Presentation" is just the name of the general model.

Is it a Z37LC6D LCD TV?

Please reply with the model number and the MFG DATE so I can assist you better.

===

Check the rear for the exact model and the MFG DATE on the FCC label.

Check for loose power cable to the TV.

Make sure the socket the TV plug into is not overloaded.

An overload is dangerous and the voltage drop will cause the TV power supply from turning on.

If possible plug the TV into a different //// empty outlet.

A clicking sound is a signal of a failing power supply or low line voltage from the wall socket.

Please update you post on the reply window.

No picture and clicking sound only


This may be a power supply problem or a shorted horizontal output transistor shorted. The clicking sound is the power supply trying to start but can't because of the overload. Stargazer
