Because you have DirecTV there is no need to use auto tuning. You simply changed inputs on the TV when you started auto tuning. Just use the input button on the remote to go back to the Direct TV receiver. Most likely it will be under Component (Color Stream) or HDMI input.

when the TV goes dark, shine a flash light on the screen- hold it very close.
if you see a little bit of the image, your backlight has failed. That would mean you would need to replace the LCD panel.

What you described here is a issue with the LCD back light or one of the inverter boards going out on you. These boards can be found www.partstore.com or www.shopjimmy.com

From what you described this is basically what I come up with, if you update me with a serial number/ model number we could get you the part number and price.

 Dear friend try to change your cables if you are using regular A/V cables, you know the white/red/yellow, use a S-video cable and or maybe try to change the Video Input settings in your TV by going in the setup menu and look for the settings that will suit your console the best, most TVs comes with adjustable Video settings that ranges from Normal, Theater or Cinema, Video Game etc. pick the one that works with your systems. If none of this works try to contact the place you bought the TV and ask them for warranty repair or exchange. good luck!

You have fallen into the 'let's see if this fixes it' form of television repair. The course to become an engineer is 2 years. You need to be able to correctly diagnose boards at component level. It is far cheaper to take the television to a service technician and correctly diagnose the problem and replace the correct single part that failed. The other very real problem is that you have no way of knowing that the 'guaranteed parts' that you bought was actually working? Did you notice that is says 'no refund, no return'? Did you know that most of the boards come out of failed sets? Only techs can return faulty boards and they will tell the supplier why that board they sold is faulty.

Do you mean that the closed captions are on? Disabling this depends on the video source. If the source is TV (OTA or cable with a coaxial cable), then you need to access the Settings icon after pressing the Home button on the remote. Then go to the Accessibility section. Locate the Closed Caption sub-menu and disable the captions. (Click the appropriate button on the remote to enter menus and change settings.)

If the source is not connected to the RF input, then you probably need to disable the captions at the source. This will depend on the source. For some satellite boxes with a main set-top box that serves a secondary TV, you'll need to disable the captions at the main set-top box. For an ADB IPTV box, press Menu on the remote. Then go to Settings with the arrow keys and press Enter. You may need a pass code from the service provider. Go to the Hardware sub-menu and enter the Audio section. Finally the captions can be disabled in this section. Check the documentation for your source.

If you mean the Voice Narration (audio description), you need to go to the Audio settings section from the Home screen or the Accessibility section (as above) depending on the TV model.

I hope this helps.

That clicking sound is the safety relay not clicking in to protect the TV from frying out. The problem is most likely the power board.

Check capacitor with a digital volt meter. In my Samsung, the TV has a chip that check to see if all circuits are OK before turning on the set. Samsung has a power, input and video boards. The problem is when it check the high voltage circuit and it does not have 390 volts, the chip turn-off the power instead. (It is a safety thing.) You can buy a new power board or fix it yourself. The power board is where the 120 volts AC is plugged in, and near the 120 volts is small transformer, then you will see a capacitor rated 100 uf at 450 volts. Check for 390 volts here. If the voltage is less, then replace this capacitor with a 350 uf at 400 or at 450 volts.Samsung used a "small" capacitor when it should have ordered at large capacitor. Good luck.
