Default Samsung UN32EH4003 Power Cycling

Hello.

I just received a Samsung UN32EH4003 TV. When I turn it on, it power cycles on and off. Screen comes on and then off, powers off, resets and starts again. This is the first time I have come across this. Has anyone else encountered this problem in a newer model TV? Trying to determine where to start troubleshooting this type of problem.

Thanks!
Joe

Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

Same make and model of the TV?
If it is then you should upload good clear pictures showing all the boards and how they are connected together and go from there.

Hi,

I think this is the same problem I had. Take a look at this post.

If the cap is not bulged, remove and check the capacitance. I bet it will be very low.
