    Daytek 42DKf3 Volume at 100%

    Picked up this Daytek 42 inch tv .Can not find little or no info on this tv.Not sure who makes this .Picture is perfect. Sound goes up and down by itself. It is not a Remote problem. I did not get a remote with it.Was reading and someone suggested the manual panel on the side being stuck. I unplugged it and it does the same thing.Volume goes to 100% with volume bar on the bottom of screen on at all times.

    Check for bad caps but it's probably a bad mainboard. See if there is a reset procedure before replacing it though.

      This problem is almost always the switches. Since it's not the switches in your case, it's the circuit that controls the switches. Inspect the switch panel connector on the mainboard for corrosion and the like.

      Do you have a multimeter?

      A working TV? How boring!

            Before you do that, try cleaning the buttons/switches/touchpad with isopropyl alcohol.

                could the board with the remote sensor on the tv itself be faulty? have you tried disconnecting that. Pictures of each of the boards in your set may help us reconise them and may have saw the fault before.I think from reading various posts the tv is made by daewoo group.
