same here. My model is :

Roku Soundbar: Version 9.2.6 Build 5203

Used to go to a green screen and now it is black and you have to totally shut the TV off to get a screen back. So not happy with this soundbar. Nothing but problems since I got it for a Christmas gift for my husband.

Marlon Manyweather  in a darkened room turn the TV on to a channel where you have sound etc. Then us a flashlight and shine it at an angle against the screen see if you can make out shapes silhouettes etc. If so you know that your backlight is not working. This may require replacing the LCD strips inside the panel or a new power board. You will have to remove the back from your TV and check the power board with a multimeter Post some good images of all of your boards with your question so we an see what you see. Agregar imágenes a una pregunta existente

If you cannot see anything (triple check) then it is possible that this is a bad main board or a bad t-con board as wella s the panel (unlikely but possible)

Of course before all of this. Unplug your TV, unplug all devices that are plugged into your TV and then hold the power button down for about a minute or so. Then plug one video source (preferably a local DVD/BR or Game console)in and plug the TV in, restart. See if that resolved it since a bad cable box can sometimes cause a dark screen as well.

Hi I am having a issue were my ONN roku tv is just shown a black screen but the sound is working

TCL repairman came and replaced parts when my tv suddenly went dark for no reason, new parts didn't work either, TCL ended up sending me a check for my tv since it was still under 1st year warranty. Waste of time it took a month for whole process, never again will I buy TCL ended up getting Samsung. I had a 75 inch, only had for 8 months, garbage

- de

TCL made me send pictures of my TV, receipt and video, the hassle alone made me want to say screw it, but I got reimbursed the entire $848, they told me to keep tv because it was too big to pickup so I sold it on Facebook for $150. These TCL tvs are garbage and they know it.

My father bought the TCL 55" Class - 6-Series - 4K UHD LED LCD TV from Costco in December 2019. It was working great until mid-May when he had the same issue everyone is describing in this forum: no picture (black screen), but the sound works when on HDMI1 (connected to the cable box). The Roku home screen did work, however, and we were able to watch Netflix. I tried all of the solutions suggested in this forum (thank you!!), but they didn’t work for us.

Here’s what worked for us—turn off the TV and cable box. Unplug the power cord to the cable box, wait 30 seconds, plug the cable box back in, turn everything on. There must have been an issue with the connection between the cable box and the TV.

Try disabling Fast TV Start in the Power section of the Sytem section in Settings. Worked for me.

Thanks, Ron! I specifically remember enabling the Fast TV Start feature when I set this TV up for my dad. I didn't think about trying to disable that during our troubleshooting. I appreciate your input!

- de

we had to unplug both the tv and the cable box, wait 30 seconds, reconnect and then power on using the roku remote; then all was working. !!!

thanks to caroline and ron for your combined tips.

- de

@ceevee35 Glad u experienced the same results as I did. Unfortunately you have to wait much longer for the TV to connect to the internet if u r running it wireless as I. I also have the Roku external speakers (great sound improvement for $150) which take time to connect prior to the wireless internet connection completion. The time to fully be ready upon power-on takes my set about 1.5min. .....better than throwing out the set. It seems to me that TCL or Roku introduced some software/firmware bugs in an update recently. Best of luck to Ron

- de

Thanks Ron, I did exactly what you said. Realized I was already disabled from that feature then I saw system reset on that list and pushed it and now it works. Thanks

Hi @carriecarlevale ,

If it is not 12 months old yet, make a claim for a manufacturer's warranty repair or replacement.

Check the warranty statement that should have come with the TV (or look in the user manual for it) how to do this.

@John Ng'ang'a ,

If you have a TCL TV there's not much information on them out there.

You may have to find out where the power is coming from for the LED strips, the power board or the mainboard, by finding the cable coming from the panel. There won't be too many wires in it (4?).

Then measure the voltage at a suitable connection point. If it is high voltage (>220V DC) it most probably is in the LED strips. if low voltage (<50V DC) the source of the supply or the mainboard not telling the supply to turn on the power.

Sorry about the vague answer but as a DIY repair, testing the power board and the power to the LED strips is the only way to move forward on this

- de

@jayeff

you have been extremely helpful. far more helpful than roku or tcl care to be. I’m working on a tv right now with this issue. Just replaced the power supply and still have the issue. Going to reset but doubt it’ll help. With your advice, I will probably have to replace LEDs.

- de

Same issue, only we were blessed (?) to have our TCL 55" work for two years and 6 weeks. Black screen. None of the resets worked for us, and I am sad to say that we also have a TCL 65". Blah. I will file with BBB just because I see there are no viable options and they do not take any responsibility for making a bad product. It's sad. But . . . at least we all know not to buy TCL ever again! Right?

- de

Same issue with a 55". I have tried all suggestions. My solution was to disconnect everything remove from mount and dispose of. Never buy a TLC again. Mine lasted less than 2 years.

I have same issue when the TCL 55R615 is powered off overnight. Next morning I get audio but no video. Found that if I unplug the set, wait 10sec and plug it back in, it works fine. Being doing that ever morning. TCL support is useless.

Hi,

When you say "is powered off overnight." do you mean that the power is turned off or just that the TV is turned off and left on standby?

If powered off and if the TV is no longer covered by the warranty, disconnect the power from the TV, remove the back cover and inspect the power board for any obvious problems such as bulging capacitors and heat stressed components

- de

Turn off fast startup in the TCL settings. Unplug the tv from the power receptacle, wait 15sec and plug it back in.

Wow, lots of folks dealing with this. I was also and it started to show no picture back in early June 2020. I have owned this 65 inch 6 series for about 14 months and then it started doing this. I learned how to do the remote control deal that reboots the TV but I needed to do that each time I wanted to use the set. I DID WIN THE PROBLEM BY UNPLUGGING THE TV FOR JUST A FEW MINUTES AND ALSO TURNING OFF ALL QUICK START OPTIONS IN THE SYSTEM MENU. IT WORKED, MY AWESOME TCL IS BACK TO ITS DEPENDABLE SELF.

I would love to find all of the dumpsters where folks took their units. I do think the problem started with the TCL software update I have read about a few months ago. Maybe like our computers sometimes after a software update we have to reboot the system to have that update stick.

Also, I visited CHINA a year ago and the TCL brand is everywhere. CNET loves the TCL line and TCL is actually the second largest producer of flat screen TV's in the world.

I just remembered. I ALSO UPDATED MY CREDIT CARD with the ROKU SETUP and I suspect that did play a role in fixing the problem. That does not make sense to me but it may be part of the deal.

There is a YouTube video addressing this exact problem.

You can watch it, but here's with a try.

Follow these steps.

Turn on the TV.

Press the home page button 5 times.

Press the curser up button 1 time

Press the rewind button 2 times.

Press the fast forward button 2 times.

The TV should start a reset and will likely turn on and off two or three times. Takes up to ten minutes.

Seems to be a common problem.

And I would watch the short video on YouTube first if you're not real tech savvy.

Hope this helps. Good luck.

I have the same TV and similar to your problem.

Did you try the reset using a series of keystrokes on the remote?

Look on YouTube for how to do that. Just search your model on how to reset.

On mine I have a black screen but I can see it's fully lit up. All the LEDs are lighted. But no images.

I can hear the clicking of the remote as chick the various buttons. So I would assume it's just a single board that needs to be replaced. And I'm quite capable of replacing the board but don't care to spend the money unless I know for sure that's the problem.

I've asked on the forum here, but sadly not one person had replied.

So don't be surprised if you get no replies either . Good luck hope you find a solution.

awesome fix, worked as a charm, did go to settings afterward and turned off quick start, I knew when I bought this set that it was cheap and expected it to not last, we will see if with this fix i'll get some more time out of it

I got my 55” S405 picture back. My issue was sound & image that could only be seen w/flashlight. I went researching on youtube. I found that most likely issue was LED backlight strips. I don't know deep electronics or how to trace voltage. But I do know system hardware replacements. It is by no means an easy repair for the novice. The replacements totaled $32. I took a chance this was it for the cost. Cheap LED strips made sense to me. I found a great youtube video on the breakdown. My TV was last gen in this model. The LED strips on 1st models were glued in; not easy to get out. Mine had 1 little screw on each strip, then each slid out easily. Kinda makes me think TCL made it easier to repair knowing they were faulty…

I can't believe how many people have this issue. Boo!

https://youtu.be/I32MBlbRWMs - video to show LED strip repairs. Each tv version of my model (55S40x) differs slightly on the breakdown.

The parts came from eBay. I had never used seller https://www.ebay.com/itm/TCL-55S405-55S4... . Just search your tv model & 'LED Strips replacement'. Costs go from ~$25 - $50. I spent a couple extra bucks & picked somebody east coast to get it faster.

- de

Forgot to mention; the YouTube video guy tries to repair his LED strips. I don't know how to read electronic scopes or repair circuitry, so I went with the $32 replacement parts.

- de

Mark-- I think I also saw your comment on the YT video you linked. Same model TV, mine also 2.5 yrs old like yours...I can see the menu/letters with flashlight test. I've tried LITERALLY everything else mentioned here and elsewhere online. Going to attempt to swap out the LED Strips. Questions...1. Did you simply replace ALL strips rather than search for the one faulty LED bulb?? 2. Could you please list ALL tools you needed? 3. Did you use the little plungers to lift the glass or can this be done easily with two people? 4. Any snafus or anything you think I should know before attempting this that you wish you had known? Sorry for all the questions but I'm not super handy or mechanically/electronically inclined so a bit hesitant. Thanks for your time and appreciate all of the posts and links.

- de

I replaced all of the strips. At startup I could see the Roku launch screen just fine for a half second, then black. It has a built-in protection that shuts the LEDs off if it senses problems. I only used screwdrivers. I didn't buy the plungers. Someone helped me move it. If the panel cracks, the tv is trash. I didn't buy the replacement LEDs until I knew I could get it out. The panel sits in plastic tracks that, sort of, click into the metal chassis. Either the top or bottom {think was top) of the LCD had this piece glued in on mine. Other 3 came up/out with, slow prying. Be careful disconnecting & reconnecting cables. I had to go back into my tv to reconnect the LCD ribbons - I had no pic but brightness the 1st time I finished. Go slow and don't pull too hard on anything; except maybe the feet posts. I had to wiggle mine back & forth to get out. Make sure to give connectors a little tug after you reconnect them.

I just came searching for answers because this happened to me today as well. Tv is less than 2 years old 55 inch roku smart TCL. Worked fine last night and today there's no screen. Seeing this now just makes me so mad. This is unacceptable. If this many people had the EXACT same issue with a car, they would do a recall. This should NOT fly with a TV.

I contacted BBB and got all my money back only because it was still under warranty, they didn't even fix it, just told me to keep the TV and my check came about 3 weeks, I am worried the other TV we purchased the same time will go out and warranty is over this month, never will I buy TCL ever again!!

good for you. I think the residential warranty is 6 mos? or 1 yr. - I didn't even bother reaching out to them once I saw their warranty and the hundreds of reports of same issue. I just bought a 55" Samsung, hopefully it lasts longer. BTW, I have a smaller 32" Samsung (not a Smart tv) that my kids bought for me about 8 yrs. ago - I hooked it up while shopping for a replacement for the 55". Picture and quality is still beautiful.

It is a disposable Telly. Let’s say it costs a median of 400 US bucks and it works fine for 14 months. That =’s basically you rented the telly for 30 bucks a month. More if you financed it.

We have found repair kits for the power supply and back lights for just over 100 bucks should you elect to go the DIY route. Yet if you DIY it route and mess of the unit beyond repair. SOL. Many technicians do not even wish to touch these units. Very little profit for them to do so with no guarantee that it will 100% cure the issue. Should you get one local tech that will do it for 100 bucks for labor on top of the parts. Now your out 250 bucks and the unit may not work the same as it did out of the box.

I’ve been following this thread since Oct 2020 looking for solid answers before I just chit can the unit. I have succumb to avoid any tech chit made and controlled by Chinese companies and CCP. Terribly sit-rep for USA consumers.

My problem was not a black screen, but a dark screen, that appeared to not have a green added to the red and blue to make a full spectrum of colors. I checked our network on YouTube channel, and it had the same problem, so I knew that it was not only a cable problem. I also checked the settings to ensure that the brightness was properly set, which it was. I also unplugged everything to reset to make sure that was not the issue. None of those checks produced any results.

I continued to research online, and searched different possible solutions. I finally realized that it was probably a connection problem, so I pulled the hdmi cable out of one of the four ports, and re-inserted it into a different one. This final effort produced the desired effects, and the picture was totally restored!

I have a similar issue and this is how I manage to use my tv

turn the tv on and it usually works fine for a couple of seconds on my PS and then the screen goes blank.

THE FIX:

I switch the tv on and instantly press the hamburger menu on the remote or through settings - Switch Sports mode on

this can be frustrating in the beginning to do it before the screen goes blank but after a few times it became routine. Disappointing but it is what it is

Once you admit to yourself TCL makes a cheap unreliable TV and can learn to live with it until you can afford another one, you've got it made.

What’s the hamburger menu?

Agregar un comentario

TCL customer service walked me through the solution. First try (which didn’t work for me), if you are able to still see the TV’s menu (not your cable or blu-ray menu). Goto settings, advanced settings, reset the TV/Audio settings. (This did not fix the problem for me. But this next suggestion worked…).

  1. Unplug the TV.
  2. Under & just behind the bottom edge of middle of the center (behind the TCL logo on the back) you will feel 3 buttons. Hold the center button for 15 seconds. This will dump any residual electricity in the TV but not reset everything else you have programmed.
  3. Replug the TV, wait a little while longer than normal for it to cycle back on.
  4. Tada!!!! It worked again!! Yay!!!!!!

TCL 6 Series Roku TV here. Same issue. worked ok for a little over a year then it started white screening when I turned it on the next day after sitting overnight. . At that point unplugging/replugging would work. After a while unplugging/replugging that stopped working as well. I could do the remote trick mentioned above (Home 5x, Up arrow, Rewind 2x, FF 2x, unplug, or the rest button. Sometimes one of those options works, other times no. It may take 20 or 30 times before I get lucky and it works. TCL support really wasn’t any help. I bought the TV in April 2019 from Walmart so it is over a year and out of warranty. This TV was in another room and barely used up until recently. So disappointed as the picture was great. My parent’s Hisense Roku TV has had none of these issues. What a shame as I bought it due to the good reviews online…but apparently that was just for picture quality not reliability.

Unplug tv, press reset button on the side of tv ( depending on tv model) and wait for few hours would bring video back after doing those steps. Then you need to either enable fast tv start or run system restart to prevent black screen recurring.

The best advice, If it's not under warranty you might as well get rid of it because you'll spend more than you purchase the TV for, unfortunately this is common with these tvs mine gave out 8 months after I bought it but luckily I was able to get a full refund the TV wasn't even able to be fixed they told me to keep it I ended up selling it for 150 on Facebook so I kinda like came out ahead, mine was under full warranty

We had 2 TCL 55” Class 4 Series 4K UHD Smart Roku TV’s, model number 55S435

Each was purchased with a 5 year warranty from BestBuy.

First TV was bought on 8/30/17, no video 1 year later (but sound). BestBuy made us go to a local repair store, they replaced main board. TV died completely in April 2019.

BestBuy replaced it on 4/25/19 with a new one, same model. on 3/31/21 the screen went blank, sound is still on. Were told we have to wait at least 10 days for an appointment.

We tried several tips and tricks, none showed any improvement.

Every time BestBuy replaces a TV the warranty purchased is considered fulfilled, and a new one would have to be purchased.

We wont to it if we get another TCL TV. It is low quality. Plus the BestBuy warranty causes too much of a runaround.
