this is foe a Sanyo dp 26649 model. I have no picture.I cant figure out how you can use headphones with this tv so I can sleep while my husband watches TV. I plug them into the audio out and nothing. Not the audio l/r out but just the "Audio" single plug which uses a different plug. we bought a headset for ipods the dealer said would work but doesnt. Any help here would be greatly appreciated on how to do this. I need my sleep.
