Rca l42wd22 no sound
when I hook up to HDMI I have a good picture but no sound. sound comes on for a few minutes when you first turn it on but goes out after a few minutes. also when I hook anything up to the rca jacks I get no picture or sound. only get picture from the HDMI inputs. I hooked a ps3 to the HDMI inputs and don't get no picture with this. hooked my laptop up to same HDMI and I get a picture. hooked my cable up to same HDMI and get picture but no sound.
