No, there is no audio. Yes, the cable box is on (and goes on and off appropriately, using its own remote). I've tried the unplugging-replugging--no luck. Yes, the remote is set to TV, but that doesn't work nor does using the switch below the screen.
Prior to this episode, the "blue light" around the power switch was on when TV was "off." Normally we used the cable remote to turn on all components (TV, cable box, DVD) or occasionally the TV's own remote, but this time I used the power button instead. The blue light went off; and from then on, it's been completely unresponsive.
Can you help? Thanks!
No. Can't get any sign of life at all. Normally, when you turn on the TV using the remote, a blinking red light appears until the picture shows up on the screen. Currently there is no red light, no blue light, no clicking sound--no indication at all that the TV is connected to any sort of power source.
(Thanks for replying!)
[FYI, it's 8:00 p.m. in Oregon, and we have to go out for an hour or two. I will look for your reply ASAP when we return.]
