TV shows picture briefly and then goes black. Yesterday we had the same problem and successfuly used solution #3(power off box and remove cable, etc.). Tonight, that doesn't work, nor does unplugging cable or anything else!
Good evening djalberts
I can give you a hand to resolve this. Can you please let me know which type of cable box you're using and whether or not there is an external hard drive (for PVR functions) attached to it?
