Tried other box. Same problem. This was via s-video, so it's not the input. I let it sit for 6 hours. Nope. I've opened the rear and looked inside. It does not have the "bulging" capacitors as has been described by other users having the power off/on issue.
SO? Now what? Help me!! <Please??>
This problem just started yesterday. Thus far, the TV had been great. Here's what happened:
Was watching TV on an HD channel. Screen goes black & audio continues. I shut off power to TV & cable box. I noticed that the red indicator light in the power button stayed lit, so I also removed the HDMI cables. Let it sit for a few mins and no problem...for a little while. It happened again...so, I did the same as above. This time, when I turned the TV back on, I went to a non-HD channel. It worked the rest of the night.
This morning, however, while on non-HD ESPN, It did it again. Did the reset and it worked again (for 3 mins). Please help me diagnose. I will attempt to switch cable boxes as I have seen suggested previously and will report back. However, I don't have another HDMI box. So, if it is an HDMI problem on the TV end, it will take a new Verizon box to be sure. But, I will try the non-HD box anyway as a starting point.
