UN55D6000SFXZA Version H302 Power Cycles on and off

My 55 inch keeps power cycling on and off repeatedly. Have tried different outlets unplugging letting it sit. Nothing is plugged into the TV except power cord. Checked voltages from the Power supply board and a couple of the voltages periodically drop to 0 and then come back up. Replaced most of the capacitors on the power supply board but the problem persists. I have a power supply board on order, but feel this may not actually be the problem. Any ideas?

model number is UN55D6000SFXZA, Version H302.

Unplug the TV for 30 seconds.

  • Unplug the TV from the wall outlet or surge protector for 30 seconds, and then plug it back in

Try to update the software.

  • In some cases, a software update can correct the problem. There is a risk, however. If the TV turns off during the software update, it could damage the TV. Updates can take up to 30 minutes depending on network speed, so if the TV is not turning off too frequently, try updating the software.

Disable the Power On with Mobile option.

  • TVs that can connect to SmartThings can be turned on using compatible devices, sometimes automatically. However, if abnormal "power on" signals are sent through the wireless network, they will trigger this function and make the TV turn on.
  • If you do not want this function, navigate to Settings > General > Network > Expert Settings > Power On with Mobile, and turn the setting off.

This type of issue will need to be addressed by having the unit serviced. If the unit is in/out of warranty you can use the following link to find a list of service centers near you that can do the repair: http://www.samsung.com/us/support/service/location.

Yes, I saw these stock answers already and would not have posted if they worked. As I stated in the problem discription the TV does not stay on for long before the power reset. A software update during this short time would not be possible. Disabling anything via the menus is also not possible. Thanks.
