The power supply will sense if the set is 'drawing' too much current and switch itself off. This could be the case here. The power supply board may eventually go completely bad.

The remote has stopped working so the only way I can change channels is on the actual tv


Easy way to test an infrared remote is to point your camera at it and then push a button on the remote and look for the purple color on the camera, If you don't see the color AND the batteries in the remote are new AND installed correctly, it is time for a new remote.

One for all universal remote i am trying to program my seiki television. I lost the original remote and the power button on the television is broken so I cant turn the television on


Always better to buy a genuine replacement. The problem is that if I remember correctly, Seiki don't actually make the television, which is why it never features in the Remote Code Lists. I have just checked three sites.

Sound is pinned at 100% output. Remote nor physical buttons on device are working.


If any of the buttons on the remote or tv work, then try going into the menu and turning the sound down manually.

Veon tv manual


The eject button on the remote appears as an upward-pointing arrow with an underline - see below image. The eject button on the TV has a similar symbol.

However, I suspect that in your case, you might not be having a Remote.

This link says that your TV doesn't come with a Remote and DVD cannot be ejected without the remote :

Devant ER 31951D remote


Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Pull up older posts. If the remote control is found OK; check and replace the infra-red sensor inside the TV. Contact any service technician.
