Why does Samsung led flashes like strobe light.

I have a Samsung led model UN60H6203AFXZA and the problem I am having is the screen flashes like a strobe light as soon as I plug it in it starts flashing on and off. No troubleshooting required even if I do disconnect the cable that goes to the hdmi and other connections. LED's still flash. Do I just need to replace the power board?

Check power supply regulation. Do not keep it on for too long as the flashing might damage the backlight LEDs.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Blinking codes details to many popular brand TVs are given. If blinks continue without any pause, the main board is faulty. Search the sites by type in the brand name to your set, in its search box on the right column. View it on a desktop or in web View. Mobile view has no search box.

Testimonial: "I tried the links you provided and they for some reason no longer work. I purchased another power board and the led’s continue to flash. The small red light by the On/OFF button flashes twice stops."

MY SAMSUNG SMART TV WONT TURN ON, THE LED POWER LIGHT WILL FLASH 10 TIMES ABOUT EVERY 30 SECONDS, BUT NO PICTURE. DO YOU THINK IT COULD BE A POWER SUPPLY

Good early morning.
I am certain that you have checked the power supply. My experience with similar problem is to check all connections.
  • from where the wifi comes into the house
  • To the router
  • From the router
  • to the tv
  • If there is a HDMI connection chech that it is in the right contact
If you you can get into the menu with your remote, ichoose picture and scroll all the way down to picture options,then to picture off . If I push there on my Samsung smart, the picture disappears. Clicking enter brings me the picture back.
. Hope it does that for you as well, Kolbrun

My coby flatscreen comes on and works but strobes flashing light but works good just with strobing light ! whats going on?

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

My Hayward Colorlogic pool light is flashing like a strobe light

That particular swimming pool light has a power-cycle feature that allows you to change the way your light illuminates your pool simply by turning it off and on. A strobe like effect is one of these power cycles. To change it, simply turn the switch off and then turn it back on within 10 seconds. It should reset to another cycle. It is is left off over 60 seconds, it resets to the first cycle, which could be the strobe. If cycling doesn't solve the problem, your bulb has probably malfunctioned and you are going to have to have a repair tech service it.
