The screen is very dark, if you look closely you can see an image, but the screen is almost black. I'm still getting audio without any issue. This issue is on all video inputs.
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

This is a foreign voltage issue. It's very high voltage with minimal current. Milliamps to say the least. It is not dangerous. The only way to test for this voltage is with a foreign voltage tester that low volt techs and electricians use to identify charged or hot lines. You can dump this foreign voltage over the coax cable coming into the house as long as the coax cable has a ground block outside where it comes into the house. If the DTV and XBOX are unplugged you say that it doesn't do it, correct? What other peripherals do you have plugged i when you unplug these two? Well, if that's the case then the problem is not your TV it's either the XBOX or the DTV. I diagnose these issues for AT&T Uverse and have come across similar situations like this one. How this voltage comes across the frame is too complicated to explain in this forum. First, determine whether or not it does it with just the DTV box hooked up. Isolate the problem down to the particulars. This voltage will pass over any connection between the peripheral and the tv. this voltage will cause other small problems like voice and video not sync'd, delay on channel changing, automatic shutdown of individual peripherals, etc. Do you have any of these symptoms? I can help you, but we need to establish a question answer forum to go further. Answer these questions and try to get more troubleshooting data. Excellent narrative by the way. Let me know.
