Screen goes black, audio continues.

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, 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.

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??>

If the screen goes black and the audio continues, this still points towards a HDCP (copy protection) error. When the cable/sat boxes on the market don't detect that they're sending a signal to a television, or can't make that HDCP connection, the picture will stop, but the audio will continue.

In many cases, this has been solved by calling up the cable/sat company and requesting that your box be "refreshed", reset or updated.

There's no way that's the issue. I've tried three different boxes now. All having the same's via hdmi, s-video, component and regular coax. It is definitely not the box. All other tvs in the house work with these boxes.

So, I am totally capable of fixing this myself. I just don't want to order the wrong board. I've seen people mention the T CON board. I dunno what T CON stands for, but others sharing my issue have resolved theirs via replacement. Allegedly, it's the board near the top of the screen itself. They go online for about $140.

Any other thoughts on resolution is welcome. But I want to make a move on this shortly as the 19" "flat" tube tv which has replaced it is dismal at best.
