This sounds like you need a smartcard or your current smartcard is not working anymore. Your local provider probably "scrambles" the service over the line and you need to buy a certain subscription to see this channel.
Please get in contact with your cable provider.
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/
Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.
It usually means the screen unit or panel is damaged--they are very fragile and even a slight blow can destroy them---Panel alone if bad costs much more than another set--seen one where a two year old just slapped the screen (not very hard either) and destroyed it Panel.
I will attach a few photos---no two look alike except if a starburst or odd pattern does not move---Panel.
You can either replace the screen or you can work on your laptop with a broken screen. Replacing the laptop screen is quite costly depending on your laptop model and availability of your parts.
Hi, My Name is Jorge K. My family owns Dynex T.V. 32 LCD, we bought the tv at BEST BUY=BBY and we did not buy any warranty from BBY all we had was the fatory warraty that last a year. we had the same problem after five months the screen of that tv stop working and all we watch was a WHITE SCREEN.
Solving the Problem:
If you the orginal owner and bought the tv from BBY, you should call Dynex " the phone number will be on your owner manual tv.and it should be free if you live in the USA" and explain the situation about your TV. It might be a white screen or different problems. You should have your BBY receipt from that tv. because they will ask you for information that the receipt has. After you finish complaning with Dynex, Dynex will transfter you to BBYbecause Dynex branch is relate to BBY as the manual explain us. You will be talking to BBY Geek department. Geek department will send a Technician to fix the T.V. The Technian WILL NOT BE ABLE TO FIX THE TV THE SAME DAY BECAUSE HE/SHE WOULD NEED TO ORDER A REPLACEMENT PART TO FIX THE TV. Generally the tech will need to order a NEW SCREEN TO REPLACE AND FIX THE PROBLEM, but pay me no mind. Haha I am not a t.v. Tech. haha.
Because the Tech will not able to fix the problem the same day, he will give you a phone number and you will have to call BBY and ask if your replacement screen arrive. If they are unable to get your new screen, Dynex will give an order to change the T.V. for a new one. and they will give you a change number that you must write. Then you can go to the BBY where you bought the TV or any BBY and get you new Dynex TV. BBY will try to charce extra money because my, your or our Dynex tv model might be old and had a lower price than they new Dynex tv that BBY has right now. I think you will have to convince the manager from BBY home teather department not to charge you extra money. My father was able to convince the manager and we paid nothing for the new tv.
Solution if you Dynex TV is not from best buy or has more than a year:
haha YOU OUT OF LUCK, You can try call Dynex first and deal will the problem. You can also try to replace the screen but it might not fix the tv and replacing a screen could be costly, haha I just prefer to buy a new TV and no invest in something that might be trash if that solution doesn't work out. Risky, Please play save with your money and don't gamble. HAHA.
If i hurt any feeling, i bet for forgiveness and I wish that everything goes alright with your tv and your life.
