I have a 55” TCL Roku TV (55S405TNAA) that was working fine, then the next time it was turned on has no picture. Clicks are audible when adjusting the volume or navigating the menu. Flashlight test does show the menu. Is this most likely a panel issue or an LED strip issue? If one LED strip goes out does it deactive the rest? I feel confident and comfortable that I could replace any of the panels. I do not feel so comfortable about replacing the LED strips after watching a youtube video…hoping its not that. Thanks!
I am repair tech. From the troubleshooting you have strong chance you have LEDs bad. This model is easier than most to change LEDs. There is 2 version of LED strips. You will need to use numbers on the strips and/or LCD panel number to get correct parts. Do not order by model number alone. Good luck
@kzoomarine check your power board first. Test the LED output connector with a voltmeter and let us know what you get. It could be the power board. If it checks out ok…….well I am not going to say it but you know what it most likely will be.
So, my 65” tcl Roku just went black. It has sound but the display not showing. Had it 25 months. When using the flash light I can see the display faintly. So is this a backlight inverter/ led problem,or something else? Haven’t had a chance to see look at the model number yet but where can I get the replacement parts from. Of course it’s sad but I Love working on stuff like this in my spare time. Any help will do. Tried the resetting mode thing and replaced both the hdmi and power cord already and it didn’t help. Tv will flash good picture for a fraction of a second then go back black. Thanks
TCLs are known for bad LEDs. I had a 55 inch that quit at year two. Has sound and picture (you can see it using a flashlight), but no backlight LEDs to be able to see the picture. The lights turn on for one second when tv powers up and you can see which LED is bad, then it goes dark.
