Where the defect is, and what it could be is not important when you don't have enough electronic skills to do the repair yourself. Could be one or more defective capacitors or a bad connection on the main board or even on the power supply. I would check there, but not skilled? Then consult a tech and ask what it will cost you, before you ask for repair. Repairs can be expensive, new TVs come in all prices and these are dropping still.

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Try unplugging it for 30 seconds and see if it resets. If not, take the model # and get on the internet for the manual and go to trouble shooting page. It should answer your questions

TV wont cut on it makes a clickin sound but dosnt come on . if I keeppushin the button it comes on after a while.


Your TV most likely has faulty capacitors in the power supply section of the TV. This is a failry common problem.


  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.
2c07611.png The number one cause for the symptoms above are faulty capacitors within your Plasma or LCD TV. The number one reason that these parts fail is that TV manufacturers often times use lower grade capacitors in their efforts to reduce costs. After several years these lower grade parts will tend to fail first. To insure that these parts will not fail again its imperative that they are replaced with high temp, high quality, low-ESR caps. You can find the parts online from sources like Digikey or you can get complete reair kits incuding the parts, repair instructions, and support from www.TvRepairKits.com

I hear the fan almost non stop while the tv is on.


You have a bad color wheel. The color wheel is located in front of the lamp, as the light shines through it as it spins. It is made up of different colored segments of glass, and one of the segments has came loose and causing the vibrating humming noise. The reason I know it isn't a fan is because the fans will continue to run for about 30 seconds after the set is powered off. The click you hear is the relay cutting off the fans. The color wheel cuts off as soon as you press the power button to cut the set off. I've replaced many of these at our shop for the same problem.

Samsung Tantus Model 553W HDTV1080i, when you turn the tv it just has a black screen and makes a clicking noise like it is turning on and off


Samsung has had a issue with several models, with power supply going out. The clicking noise is what lets you know it is the power supply, it is teying to cut on but has not power from the board so it cuts off. I would call Samsung and see if your model happens to be listed as the models they are covering the power supply for, your exact model number is HCM553WX. If that model is not on the list of covered models, you can ask Samsung what to do, because parts for your tv are no longer available. Hope this helps. You can reach Samsung at 1-800-726-7864

2 tv's when I try to cut them on they make a clicking noise


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.

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.

If you want to DIY you find parts here, a common fault is PSU, but part must be tested before replacement.
