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.

Hello,

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.

Thanks

 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!

It was thrown out for a reason, and probably because it is uneconomical to repair. Take to a repairer for a quotation to fix it.

This explains why, and why you can't diagnose television problems on an online forum. The television sections are really only for help with manuals and remote codes.

Here are similar questions that we see often.
Question:

I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ? Or

Turns on and sound works fine, but the picture is distorted (solarized? polarized? not sure what the term is) I replaced the main board, but that didn't fix it.
Or

I have an LG 55LM6200-UE with a dim lower-left. I just replaced both LED strips with no resolution. There is no physical obstruction visible, so this has to be a cable or board problem, right?

So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work as it should! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what it does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part you put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'NO Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous sellers use it as an excuse to get money for selling items that may, or may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $5 in parts and a couple of hours labour. It's not the fix you want to hear, but it is the best advice.

take it in for professional repair, it is by far the cheapest option than swapping out boards that may or may not be faulty. You need all the test equipment and the knowledge.

If you power on your TV but you do not see the menu options, or any video display - just a black, blank screen, and possibly no audio as well; try the recommended steps below to resolve the issue. Check if the status LED, in front of your TV is ON. ... To confirm, point the TCL remote towards the TV and press any button.
