Question:

How to fix the unexpected auto power off/on problem on my 2012 Samsung LED TV?

Answer:

There have been reports of some 2012 Samsung LED TVs powering off and on unexpectedly. This issue has been found to occur due to the TV's interaction with certain DLNA-connected devices such as the Sonos network sound system, TVMOBiLi, and others. Affected models include LED EH5300, ES6100 through ES8000 series TVs.

To resolve this issue, follow these steps:

Disconnect the TV from the network:

Remove the Ethernet cable.

Connect the TV to a different wireless network.

Manually enter all 0's in the manual network setup.

Wait for the next firmware version to address this issue.

Corrective firmware versions currently available:

Echo-P Boards: 1017.8 or higher (LED ES75*0/ES8000)

X10P Boards: 1012.1 or higher (LED EH5300, ES6100~ES7100)

If you already have the corrective firmware installed but continue to experience the issue, your TV may require servicing.

In case the auto power off/on problem persists even after disconnecting from the network, proceed with general troubleshooting methods.
