I have a Gateway p46m103 flat screen television that will only turn on after plugging and unplugging the power cord many times. It would eventually turn on each time I tried this. Now, however, the green power light comes on, and I can hear it is on, but the screen is all black. I even tried pressing the Input button on the front of the television, to see if I had accidentally changed it, and even the icon on the screen will not show, to see if I am seeing the cable box, or the dvd player, etc.

Hi, I've connected a Philips 42PF9946/79 Plasma TV to a Beyonwiz DP-Lite i Digital Set Top Box. The connection is through a HDMI Cable and TV is viewed on the 'HD' channel/mode. Previous to the Beyonwiz STB I had a DGTec STB connected that worked fine, but now with the Beyonwiz connected the top left corner of the screen shows a permanent 'HD-D' icon. I cant work out how to remove it. Can anyone help??

I have a JVC LT-42e488 LCD tv. Bought it in 2008. Last week in the middle of a movie, the screen washed out. I can still see what is going on but it's washed out so much if gives you a headache to look at it. Whites and Grays and pinks and reds are too bright. It does it on DVDs and cable. Can you give me an idea of what may be wrong? I'm desperate and afraid to get taken advantage of at a tv repair shop. $50 to tell me what is wrong with it and who knows what else.

LCD television starts normal, but after 2-3 secs, the screen turns black and remains black, no picture, but sound is still there. All cables have been checked - all possible input channels have also been tested to see if they produced any images onto the screen.
