This is a full TV repair tutorial for the Toshiba LED TV model 50L711U18. The TV may come on for a few seconds then the screen goes completely black but you may or may not still have sound coming through the TV speakers.
In some cases the TV screen will flash once when powered on but will still go to a black screen.
With these Toshiba televisions, there is a leaky backlight led that will cause this Intermittent black screen problem. In some cases this TV may stay on for minutes or hours before the picture goes completely black.
This is a full and detailed TV repair tutorial of this particular model from start to finish.
Where also going to talk about why people leave those ugly yellow Energy Guide stickers on the front of the TV well after they purchase the television.

I learn a lot from your videos on the different types of TV's and how to troubleshoot and repair them. Like the way you discuss and show the real world problem then provide a real world solution. Appreciate you sharing your expertise.

I gotta tell ya...that was pretty informative. I initially figured that the problem was going to be at the inverter but.... So, thanks for the tips on disassembly, replacing the LED's and reassembly. Now I'm gonna go shopping for LED's. Thank you again.

Great videos as always. I have a "55" of this tv. It had a dim picture, test the backlights and they all lite up, using the tester. All of the ground screws on the boards weren't tight. After I tightened them up, the picture came back to full brightness and haven't had a problem with it since.

I came up on two of the exact same TV's one does this & the other has a cracked screen so decided to keep one for parts & the other just going to change the screen. Just a sweet score for free. Another man's trash another man's treasure. Thank you for your help with the t.v. on how to take apart helped me a great deal sir❤

Hey Big Dog. Appreciate all the videos and keepin it real. Lots of great material to learn from. I understand how to diagnose the LCD screen, T-Com board, power supply and backlights all thanks to you. When going through the videos, there isn't much talk about troubleshooting the main board. Could you make a general troubleshooting video like you did with the power supply board? Just trying to learn and understand, thanks.

That takes some of the mystery out of electrical problems. Thanks! My problem seems just a little different. I have the Toshiba 49L510U18 which must be very similar to this one, though I don't think this model is a Smart TV. When I turn it on I get the Toshiba splash screen replaced by the white 2" wide bar across the top with "HDMI 1" visible to help set up the input. That stays on for maybe 3 seconds and then the screen goes dark. Since I only use this TV as a monitor for my computer, when I start it up and the splash screen goes away, I can see the computer beginning to start up, but the screen goes dark before that can happen. Is this the same problem as in this video? What causes the other rows of LEDs to go out if just one row is fluctuating or bad? Are those LED strips available on Amazon or another source?

It would seem more fitting if you buy the LED strips and fix it yourself just like he showed you. Then you could pay him the cost of the labor you saved in appreciation.

IDK same reason they leave the tags hanging off their shoes, or wear an afro pick in their hair I guess. I'm assuming it's for a different reason then why they leave the plastic on their furniture, ain't gotta worry bout getting that soul-glo on the TV or shoes.
