I have Time Warner digital cable, and certain channels have sound, but no picture. Is it my tv set, or cable?
Answer:
OK here is your problem ignore the rest call time Warner for a service call they dont charge for service unlike dish the problem is you have a low signal level coming to the box this can be caused by a number of factors bad cable to house from pole bad fittings on the cable etc or the one problem that happens most of the time is the customer decides to play cable guy and installs a splitter from radio shack on the line leading to the cable box that decreases the signal to the point where it starts to break up example black screen or lines and squares appearing on the screen this is called pixelation call the company they will fix it at no charge
its the cable box
unplug cabel box and plug it back in after 15 seconds, and let it sit unit the Clock time comes up. Re-try it. If still the same thing, lemme know what kind of tv you have, make and model.
Ones of the problems I have with my TV is it got to much control that some time I don't know if the TV is in digital or in antenna or something also. The only I can recommend to you is to tray to read the everything it is possible about you TV and then go to setting and tray your best.
