Samsung 4k TV turns on then immediately off and just repeats?
Hello All,
So my 4k Samsung UN55KU6300F just went out over the weekend.
I didn’t think anything of it, but it tries to constantly turn it self on then off.
I’ve done initial resets and everything and still nothing.
When I try to turn it on the tv will actually turn on for a second and you can see the screen light up then it just shuts it self off and will repeat as if i’m constantly trying to turn it on.
The Red light stays solid then just flashes once when I attempt to turn it on. But otherwise it stays solid like it would normally.
I’ve opened the tv up and both boards look find, none the the capacitors look blown or swollen. There are also no burn marks of any kind that I can see.
I’ve been looking this up all weekend and most of the time people were able to spot a blown capacitor. Or simple resets ended up helping them. And I couldn’t find anyone with the same issue that I was having, it all seemed to be close but not anything the exact same.
So what troubleshooting techniques are there that I can try and pin point the issue?
Cette question est-elle utile ?

Power transistors and diodes are common failure components in switch mode power supplies. Voltage and continuity tests. May require unsoldering components for testing. Beware residual high voltage may still be present on the filter capacitors even after the unit has been disconnected from it's AC power supply; safety requirements dictate discharging capacitors before working on circuit board.
