screen and sound goes blank for a few seconds. The picture comes back to normal but sound is low and needs to be increased.
Hey Muktesh! I would try using other HDMI cables, as some faulty ones can cause unstable connections. Sometimes when a “new” (new meaning unplugging and plugging back in a video source) source get entered some settings will be reset, and that’s what would be causing your sound settings to be messed with.
