Re: problem with tv, box and remote ---no picture, tv light does not stay on it shuts off after a fe
It looks to me like you are trying to use the cable-remote to turn on both the cable-box and television at the same time. If the remote is not aimed properly onlt one device was turned on. Hitting the remote all on button again will turn off the device which was on and turn on the off device.
The fix is to use the television remote to turn the television back on or off to be the same as the cable-box.
