Hello,I have read all the other forums on this topic and have tried all sorts of things such as going to the display settings. The tv is not picking up the signal from the cable. If the cable is unplugged it will say so and then when I plug it in it just says no signal so it reads that it is plugged in. Also a while ago, it started not working when I would sign in under my user account so when I signed in as my daughter's it would work, which I always thought was odd. Now it does not work in any of our accounts. Any suggestions?
