headphones work for 3-5 minutes and then go dead
I have fully charged the headphones overnight several times with the headphone power switch turned to off position, properly positioned on charging rack, and rack's green power light is on. I turn on the headset power, light turns green, and the headset goes dead in 3-5 minutes of use (headset power light is still green - still charged?). If I disconnect and then reconnect the charging unit plug into the headphone output on the TV ... headphones work again but go dead again in 3-5 minutes. What is going wrong? Regular corded headphone works great all the time, so don't think it is in the TV headphone jack.
