The TV is not turning on because there is an internal fault, and TV is on special diagnostic mode called protection. The clicking sound is not a fault, but it is the consequence of a fault. It is the protection circuit that keeps shutting down the unit to prevent more damage, after a fault had been detected.

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.

Problems can often occur with even relatively new Samsung LCD, LED Television. Some customers report their screen going black shortly after turning on the television, and flickering picture even though the TV's speakers continue to produce sound. You can test and rule out a number of things before concluding that your TV has a hardware defect.
First, check the input settings of your television. Often, users will experience a dark screen when first turning on their television if the selected input corresponds with a turned-off or unplugged input, such as a gaming system or DVD player. If the problem persists, try reconnecting all cables on the back or sides of the television. It's possible that one of your cables has gone dead. If you have access to other cables, try swapping these in and see if the problem persists. Some customers report that turning the television off and unplugging it for an extended period of time, up to 24 hours, can fix the black-screen issue. Samsung TV - Power Supply Issues If you've tried all of these suggestions and problems persist, it's possible that the power supply inside the television is defective or broken. The power supply for most Samsung LCD, LED televisions will cost around $150, with labor costs of around $250. Unless you have a fair amount of TV repair expertise, this is probably not the sort of repair you'd attempt yourself.

Try plugging the "cable" into another tv ... if it still does it then its the cable.

My samsung tv screen just blacked out. how do i find a reset button


Samsung is known for producing high-quality LCD televisions with excellent imaging and sound. Unfortunately, LCD televisions, like all electronics, are subject to problems on occasion. Common Samsung LCD problems include a television with sound but no picture, sometimes due to a faulty power supply. Although these problems can be difficult to fix by yourself, it is sometimes possible to extend your television's warranty by contacting Samsung.

  1. Diagnosing and Fixing A TV With No Picture
    • Problems can often occur with even relatively new Samsung LCD TVs. Some customers report their screen going black shortly after turning on the television, even though the TV's speakers continue to produce sound. You can test and rule out a number of things before concluding that your TV has a hardware defect.
      First, check the input settings of your television. Often, users will experience a dark screen when first turning on their television if the selected input corresponds with a turned-off or unplugged input, such as a gaming system or DVD player. If the problem persists, try reconnecting all cables on the back or sides of the television. It's possible that one of your cables has gone dead. If you have access to other cables, try swapping these in and see if the problem persists. Some customers report that turning the television off and unplugging it for an extended period of time, up to 24 hours, can fix the black-screen issue.
    Power Supply Issues
    • If you've tried all of these suggestions and problems persist, it's possible that the power supply inside the television is defective or broken. The power supply for most Samsung LCD televisions will cost around $150, with labor costs of around $250. Unless you have a fair amount of TV repair expertise, this is probably not the sort of repair you'd want to attempt yourself. Also be aware that occasionally, especially with older television models, the part you need might be out of stock. Getting a back-ordered part shipped to you or your local repair shop could take up to a month.
    Warranty Information
    • If you register your Samsung LCD TV online, your standard one-year warranty may be subject to a three-month extension. Be sure to save your bill of sale; Samsung might ask you to send them a faxed copy of it when you ask for your warranty extension. If your television is still within its warranty period, it's probably best to contact Samsung and ask for a replacement television, or a professional repair service. Problems that fix themselves may crop up and become permanent over time, and you don't want to be stuck with a costly repair outside of your warranty period.
I hope you find it very helpful. Best regards.

When I turn the TV on it clicks 10-12 times and finally turns on.


Sounds like you have bad capacitors in the power supply. If you look they will have a bulg on the top, replace them and you should be ok.

Television will not turn on


The symptom indicates that there is a shorted board or multiple shorted boards and needs to be looked at by a trained Samsung tech.
