RTRQ6522-US Power indicator light flashes on/ off steady. Before the light was always on steady. Won’t turn on with remote and no buttons on TV. Tried unplugging overnight. Still same.
@browns46 Okay so now I get it. I think ;-). You have a new power board everything works except you have no sound. Okay got it. The audio coded and amplifier is on your main board. Check to see if there is anything that looks odd on that. Make sure that all your settings are correct. also, check your connections on how you receive your programming. Sometimes a bad HDMI cable get do this. Check all different inputs and see if you have sound with any of those. i.e. composite/Coax etc. Connect a DVD player or a game console and see if that changes the audio.
