I have seen a few of these TCL TVs that have a problem with the backlight. In this video I will show you how to repair a very common problem for cheap TVs. This TCL 55s401 needs a replacement backlight. Lots of TVs with similar problems get thrown away because large televisions are getting cheaper. Repairing your old TV can be a fun way to save some money and avoid contributing to the growing E-waste problem.

Thanks for helping fix our TV! We've been using it so much since! Also thanks for the shout-out!
I am all for repairing. If I can make less e-waste, that's a big benefit for me. Great video.
I'm glad there's still a market for these budget TV parts. 100% worth doing for someone like me who doesn't connect to wifi and use smart features on the TV itself.
Agreed. I love tinkering with cheap TVs. Thanks for watching!
This was awesome, thanks for sharing the repair.
The backlight just went out in my tlc TV and this video was just what I needed! Thank you so much for your time to help teach a new skill :)
Thanks for watching and Subscribing! ❤
I went to goodwill when televisions were half off and got 2 functioning 720p flat screens for less than 40 dollars
It'd be cool if there were any alternative control/main boards for these TVs. I've got an extra one I'd love to de-roku or at least get some native Component inputs.
Now that would be awesome.
First off, thank you so much! My 55S405 was fixed by following the steps in your video!
Unfortunately, I ended up getting a big drop of sweat on the diffusing plastic layers. I tried to dab it off with a microfiber cloth but it left a biggol smudge and of course it's showing up on the TV picture afterward. I did NOT try to use any cleaner or water for fear of making it worse.
Is there any way to clear that up or do I just need to buy a new sheet?
I'm glad you got your TV working again! I would probably try a plastic safe cleaner to clean any of the layers that got wet. You may also want to clean the back side of the LCD. Just make sure all of the surfaces are dry and streak free before reassembling. I have had good results in the past by cleaning LCDs with a product called "invisible glass." I'm pretty sure it is plastic safe. Proceed at your own risk though. It is so easy to get debris or fingerprints on the screen while assembling.
Always depends on the TV issue and the person's skill set, but largely I'd say yes. Helped 1 friend fix a TV that was just a bad capacitor that wasn't actually rated for what it was doing meaning samsung built it to fail. Another just had bad light tubes that needed to be replaced.
Thx kinda worried about buying a PCB on eBay but it certainly is cheaper than a new TV
Most of the boards you will find on eBay were pulled from TVs that had damaged LCD screens. This happens all the time during shipping and packaging. Fortunately, all the other parts are usually ok. If you are skeptical, try to buy from a seller that accepts returns. Best of luck!
Yup just ordered from a highly rated seller that guarantees it, only $40
i see a debug port on the pcb
Hello !! My son's Tv TCL 55S401 broke, please could you tell me where to order a new screen I would appreciate it, Thanks.
Usually, you can find replacement parts that have been pulled from working TVs on eBay. If your LCD is broken it may be hard to find a replacement for much cheaper than the price of a new TV.
repair and repurpose or take parts from a tv and recycle the rest if you find use for them. Ideally these manufactors should provide better parts, but sadly how the market works is selling more in mass quantity rather than building a solid product to begin with. It's sad how this has become the norm.
