Have TV Questions? Ask a TV Technician
Hello and sorry you're having problems. How long have you owned the TV for and when did the problem occur?
Also, have you gone through and reset the TV to factory defaults yet?
First, please unplug the TV from power. Then remove any HDMI cables from the TV Input. Press and hold the power button on the TV itself (not the remote), for 15 seconds and release. Then reconnect the HDMI cables and plug the set back in, then turn it on. This is a soft reboot for the set and can sometimes cure these issues you're having. Please give that a shot and simply reply back with the results.
