- 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 repaired my 55" LG for $22. thanks to one of your videos. Thank you!
I also have a 55 how many backlight strips you buy? Idk if I buy 4 or 8?
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.
I am learning about led so I am happy you are covering all the different problems that cause the lighting problems.
Great video Marc, getting loads of blue leds, it’s the phosphorus that makes the led seem white that has deteriorated and crumbled off.
They use blue leds now and add the phosphorus top,
As usual a job well done ,Compliments from Suriname May 2022
thanks for this. great professional explanations. appreciate your work.
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.
Will do, thanks for watching.
A job well done sir terrific.
It's quite obvious in the video that the new strip is brighter then the old ones. Definitely worth replacing the whole set.
Big dog what's going on, how's your day going keep up Outstanding Work 💯% and have a outstanding weekend.
Lol, love the 'bang' test.
Secure the energy guide with a couple of screws so it doesn't come off.
lol
BD I would have ripped all that plastic ish off of that TV before I started working on it..Who knows how many roach eggs and other things are stuck on that bezel protector plastic..Excellent work as usual!!
Lmao😂
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?
Mannn I be seeing so many ppl flex that cheap yellow sticker & I be like…”whyyyy” 😂
What up big dog.What^s the name of the led test metering instrument and where can I purchase it and who you like outta the Terrance Crawford and Errol Spence fight?
Just go to amazon or ebay, and search for TV backlight tester. Not sure about the Fight.
Have the same problem shows Toshiba for 2/3 seconds then goes off ! I have changed the 3 main boards but still have same problem any advice how I can fix as tv is only 4/5 years old and would be happy to try and fix it what part do I have to replace ?
Backlights, use the flashlight test when tv goes black.
@@bigdog8882 will do thanks mate
Have opened the tv it looks like all led bulbs are working but still flashes on and off after about 2 seconds , ordered new led backlights so will replace and see if that solves the problem any other things it could be ?
@@bigdog8882 I’ve opened it up and all the bulbs seem to be working but still flashing on and off , I’ve ordered new led strips for the tv so will see if that resolves the issue
@@bigdog8882 I’ve checked the lights and replaced them and I’m getting the same issue I’ve replaced all 3 boards so can’t be them ? Only thing it could be I’m guessing is the wires between the boards ? Any other suggestions ?
Knew what it was b 4 the video started!
Cuz they think they keeping it new by doing that so do i
Would my 55inch tcl roku tv be able to be fixed, it turns on it’s just a black screen and the internal screen is cracked?
NO sir
@@bigdog8882 Ok Thank You
Man i wish u was in the area i got 3 tv's with backlight problem i don't do backlights anymore
Why Not?
@@bigdog8882i dont know its to much work
I just bought this tv used at a thrift store for $70 cad. Pretty sure I got a steal and the only thing wrong with it is missing the remote.
cuz no one wants scratches on the bezels
Understandable, but take that sticker off, its blockin the view lol
@@bigdog8882 yes yellow sticker take it off if ppl still want it then find another spot that's not the front but your absolutely right great vid because of you I fixed 6 TV's with back lights thank you for your vids it really helped me out appreciate you keep on making great content
@@peterock42 Absolutely, good shi my friend.
@@bigdog8882 thank u u helped me out alot
its too bad what happened to Toshiba, the original company used to build some good stuff
They did. I had a 65" DLP Toshiba, which I loved.
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.
Probably left stickers on fridge too!
lol
Power supply failure
Whole strip this time. What Junk.
People dont turn they tvs off that's why they leds burn up new tv need to be turn off
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.
Thank you for the information. Can there be subtitles in Bulgarian?
Actually stickers help cause damage to the bezel when dust builds up under it.
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❤
Thanks for sharing
You fix my tv is crash
"Mah energy guide" LOL
Thanks Big Dog!
No problem Ron. Thanks for watching.
Hi, I have an old Toshiba 32 TV
For over 15 years I have a picture for five minutes and then the picture disappears
Only the voice will remain. What was she looking for?
With the multimeter? there are no inflated capacitors
hi where to buy the strip for toshiba
Thank you sir
Hey Big Dog, I have the same TV model apparently with the same problem. How much would you charge to fix it?
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.
