Chosen Solution
Hi everyone I have a ‘55 inch TCL Roku smart tv’. My tv was working perfect last night but when I turned it on this morning the screen was black, I couldn’t see anything. I can hear all the noises he tv makes. Someone please HELP me!
Simple solution: Do a factory reset.
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. Adding images to an existing question 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.
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.
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.
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.
Hi @ Diasia Sweat, Here’s the TCL warranty information, or search for TCL TV warranty in your location if the link is not applicable to your location .
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!
Price.pdf 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.
