What is wrong with a TV if the power light is on but there is no picture or sound?

Maybe the wire that connects to your T.V. from a DVR or other picture receiver is loose, hooked-off, or not on right.
Also, try jiggling all connections and testing them out individually. Hopefully the screen isn't broken. If it is an older cathode ray tube monitor, the bulb might be broken. If it is a flatscreen, it is probably a circuitry or logic board problem. hopefully, it is just a problem with the wires.

∙ 14y agoI know it sounds like a jerk thing to say, but check mute and check the cables in the back to make sure they are coordinated properly. I work in TV and you have no idea how many times people plug things in wrong.
If those don't work, go to the TV menu, go to Audio. If it is set to the right settings, then mark the wrong one and then remark the proper setting.
If this doesn't work, you are dealing with a technical issue and are going to have to either call support or get a technician to look at your speakers.
