Your device has went into protection mode, an internal malfunction causes it to shut down in order to protect itself.
Somtimes a physical reset will help.
Turn of and unplug device fro a couple of hours

Sony str-k1000p wen i switch it on it flashes protect and continues to jus flash protect,and no sound or anything can be done,also wen powering on the second click takes a while after the first click


If you've made sure no stray strands of wire are crossing from the red connection point to the black it may be a problem in one of the speakers. disconnect them at the receiver, one by one, until the problem clears. If you're seeing this with no speakers hooked up the amp needs repair.

TV makes a ticking sound, red light comes on but no picture or sound?


The TV is on protect mode. The Ticking sound is the protection switc that keeps shutting down the TV to prevent more damage.

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.

Flashing protect


the protector comes on to keep the amp from further damaging itself or the speakers. The buzz you heard was probably 60HZ line buzz from the main DC supply conducting full current through one of your speakers through a damaged amplifier transistor. Your stereo will need professional repair. The protect circuit basically opens the speaker relay (and sometimes shuts down the unit) to prevent this DC voltage and current from getting to your speakers until the problem is corrected.

X2gen MW19U Monitor Black screen but sounds like it is cycling


The monitor is on protection.

Test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor 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 a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor 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, faulty inverter board, faulty input board, or a fault on LCD Digital Controller 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.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

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

Clicking sound!


The TV is on protect mode. The clicking sound is the protection switch that keep turning the TV off to prevent further damage, this happens when a fault had been detected.

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.
