It sounds to be a main board fault. Before confirmation, contact any service technician.

SOURCE: My samsung TV won't show any picture/sound.

When the TV is on, need to check the back light is on(go back side & look into through)

If the back light is on -- need to exchange the Main Board
no back light -- exchange the Power Board --- 95%
exchange the LCD panel --- 5%(inverter)

SOURCE: Samsung LCD tv wont turn on

what the full model number of your tv?
the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.

pls rate me!

TV Problem Samsung UN50TU8000FXZA

You have a bad COF IC on one of the panel boards, this is shutting down the power supply from over current, bad news is the set isn't repairable, you would need a new panel to fix the set, you won't find one anywhere.

My Samsung LN flat panel TV has no picture or sound.

OCP ( Over Current Protection ) 02 blinks. There is shorted component/s at its main board. Check it. For more information go to http://electronicshelponline.blogspot.com/ There is more information about the blinking codes, and fault locating ideas described, to many brand TVs. Pull up older posts.

No pic or sound on tv Red liight flashing on tv. No response from remote. ?

You did not list Brand or Model number for your product. There are hundreds of brands and red flashing lights usually indicate a fault or failure using a blink code, More information is required to process your inquiry.

Thanks
