MY HD BOX ON MOST CHANNELS CUTS OUT AND GOES BLANK EVERY FEW MIN AND I NEED TO CHANGE THE CHANNEL TO GET THE PICTURE AND SOUND BACK.
I Have the same problem with the audio.
Have you tried pulling the power cord for 30 seconds to reset it?
It might also be the signal to the HD box. Unscrew and then reconnect the coaxial cable on the back of the HD box. If it still cuts out, do the same at the wall outlet and also at the splitter. If there is a splitter, try to bypass it.
If it still happens after trying all this, please post again with the model of HD box that you have.
