Samsung 40" LED UA40EH5000R - Bootloop issue

Hi Experts,

I have Samsung LED TV UA40EH5000R. Since today morning, it is showing continuous restart issue in every 2 seconds. As a basic user, I googled it and found few basic checks. So, I opened the back panel, cleaned the connection from dust, unplugged and plugged it back. No luck.

But, in that check I found below observation.

1. When I unplugged the cable from PSU to main board, the TV does not gave any startup sound and it did not show any LED backlight on.

#

# Then, I unplugged the cable to LED backlight. The TV got started but obviously no image on screen. But, TV did not restart again and it was on without any bootloop issue.

#

1. Then with the TV on, I plugged the LED backlight cable into PSU, and to my surprise image was back and TV was running normal again.
2. But, then I switched TV off , switched it on and it went into same issue. I repeated above two steps few times and TV was back to normal that way until it is switched off.

So, I was curious that is there something wrong with my PSU supplying power to LED backlight or LED itself has any issue. Tested the LED light in dark room and looks ok to me. Then, I checked the PSU carefully and there was one capacitor looks leaked/burnt.

Could this be an issue for this bootloop?

PSU is BN44—00496A.

Thanks in advance
