UN55D6400UF TV Will Not Power Off
If your TV is on but will not power off when you press the power button, you could be having an issue with your remote control or a faulty circuit inside your TV.
To determine the source of your problem, follow these steps:
Power the TV on if it is off.
Unplug the TV from the wall outlet for 30 seconds, and then plug the TV back in.
If the TV powers off when you press the POWER button on the remote control turn the TV back on continue to Step 4.
If the TV does not powers off then there is a problem with the remote control. Click here to go to the Remote Control troubleshooting section of this guide.
Press the POWER button on the TV.
If the TV powers off with the remote but does not power off with the power button on the TV there could be an issue with the touch sensor on the TV. Before setting your unit up for service try these two things.
Try sliding your finger accross the power button.
Have other people try using the touch buttons on the TV.
If either of these two options work then there is not an issue with the touch sensor on the TV. There are many variable that can limit the conductivity of a persons fingers. The conductivity of your fingers might not be enough to easily control the touch sensor on the TV.
If the TV does not power off when you press either the POWER button on the TV or on the remote control, then the TV will need to be serviced. Click the Create online service request button below to have the TV repaired.
The fault may be due to confused system control section inside it. If so many commands from remote control at improper timings are given to the set, this will happen. Just unplug your TV from AC wall power socket, wait for about 30 minutes or so, and then replugh and check. This process will reset your TVs system section. After switch On, reset it to factory settings. You can get the proceedings to get it factory settings from its user manaul. OK.
You have a pair of head phones? On the back of the TV there is a CONTROL input jack. Unplug the AC on the TV and rapidly insert and remove (fully) your head phone connector into this jack. Do this about 10-20 times. Plug the TV back in. Does the remote work? If so, put a piece of scotch tape over the empty CONTROL input jack. Dust gets in this jack and messes up the remote communication. I hope this helps.
