Try this Krystal: 1. Disconnect all HDMI sources from the inputs. 2. Unplug the power from TV/LCD for 10 minutes. 3. Plug the TV/LCD back in. 4. Connect the HDMI cable one device at a time. 5. Turn on the device (ex. PS3). 6. Repeat steps 4-5 for each HDMI port. Let me know if this doesn't work. - .
