Question about Televison & Video
If OTA signal, what type of antenna are you using? Do you have it rotated in the correct direction for the stations in your area? Try antennaweb.org or tvfool.com for information on what channels you should be able to receive. Antennaweb is very conservative even with the assumption of an external antenna. Are there any objects (trees, buildings) that could block the signal? If you use an amplifier or splitter, check it for damage (or remove it and see if the one tv works). Try new cables.
If your incoming signal is cable or satellite, make sure nothing has split your signal (or shifted the dish) or damaged your incoming cables. Again try new cables and check that the receiver is working if you have a set-top box.Try changing the input type (component video, HDMI, etc) if you can.
Check that your TV is set to the correct tuner (usually Menu or Setup and look for the TV and then Source/tuner line). Try rescanning for channels.
If you still can't get anything, the video board may be bad or the tuner has failed. If the tv is out-of-warranty, open up the unit and remove the shielding. Look for a board with leaky or bulging capacitors (look like cylinders on a tripod), soot, scorch marks or other obvious cracks or oozing paste. Often you can get a replacement from either an on-line parts shop from the manufacturer or shopjimmy.com. (shopjimmy sells parts from TVs damaged in shipping. The parts only have the wear of testing in the factory and have a 90-day warranty.)
I hope this helps.
