Why does a Samsung t.v un65ks8000 doesn't power on? Red standbylight keeps blinking on and off and screen lights for about 3 seconds and then out repeatedly

Bad main

Try doing a factory or initial reset on the television. If that doesn’t solve the problem, you will have to get it serviced as it is most likely a malfunction in the television itself

possible power board failure

How old is the tv set also do you have it plugged up to a power cord? Can you tell me how many times does the light blink thank you.

Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.

I hope this helps.

Hi,
If the Lamp red light is blinking then replace lamp, replacement procedure is written in user manual and its easy.
If standby/ power red light is blinking then please count its blinking and post here. It is an error code that has info about problem in specific section of tv.
You will see 3 seconds long pause between blinks so count pause to pause.

Those blinks are fault codes. To know more visit the site linked here. http://electronicshelponline.blogspot.com/

Does red light blink? if yes, please count blinks as there would be pause of 3 seconds between blinks and let me know to help you out.
