You have problems in your vertical area and also sounds like convergence issue. This will need much work on board.

You may have a case of a bad signal board. The clue was that your power button on the tv and remote are the only ones functioning. If the tv is still under warraty, call the service number to get help!

Black screen of death - DP42746


I am a military spouse and our same tv did the same thing on Super Bowl Sunday 2009! We did everything we know to do: call the company, called the repair man, etc. There apparently isn't a solution to this that wouldn't cost more than the tv is worth. So I got an attorney to start a class action:

Widescreen tv=widescreen movie still have black on top & bottom


Sorry, you didn't provide enougb information for anyone to accurately answer your question. The most important thing you omiited was the nature of your video source. If anyone does answer this, I assure you it will be a wild guess. Here's my wild guess:

Your HDTV has a widescreen aspect ratio of 16:9. For every 16 units of width, there are 9 units of height. That ratio matches the exact ratio used in widescreen television broadcasting. However, most feature films (movies) on DVD have an aspect ratio of 2.35:1 or even wider than that. These films will display with horizontal black bars at the top and the bottom, so that you can see the full image. Unless you choose to use one of your TV or your DVD player's options to zoom or crop the image, the bars are 'correct' and there's nothing wrong.

Another possibility is that you have not configured your video source, such as a DVD player, to 'know' that you have a widescreen TV. Nearly all DVD players ship configured to output using a NON-widescreen aspect ratio, so you must adjust this setting using your player's setup menu. The same is true for most cable boxes and satellite receivers.

Finally, just because your TV is widescreen, the video source itself may not be. Most standard-definition broadcasts are NOT widescreen, for example.

If you re-post your question with adequate information about which video source exhibits this problem, I'm sure you will get much more specific and helpful answers.

Lights come on but nothing shows its black.lens looks good


I have seen a few of this model and the tubes were gone in each case. Best way is to check if HV present at tube - get someone who knows what they are doing to take a look. If it is the tube, it will be expensive to repair. Unscrewing the lens may reveal that the inner surface of the tube has dark marks, also indicating possible tube damage.
