I've owned my 65" TCL Roku TV for 5 years.  A few months ago I noticed the right side of the screen was a little darker than the left but still very watchable.  Fast forward to today and the entire right side of the screen is almost too dark to see.  I've done all the things people suggest but nothing has fixed it.  Here's the rub... when the TV first comes on the TCL Roku splash screen is fine... full brightness all around.  It isn't until the Home screen displays that the right side goes dim.  Also... on occasion the problem changes from right side dim, to middle dim, and even at times left side dim... and then on rare occasions the problem goes away entirely and the full screen has normal brightness.  

Don't let the occasional variations mislead you though... 98% of the time the right of the screen is too dark to see.

The side that goes dark do you have speaker or some magnet field close to the tv? Sounds your tv has to be degaussed?

Thanks for the post.

This sounds like a hardware issue. Have you tried contacting TCL support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS. 

You can reach them here: https://support.tclusa.com/televisions or at 1-877-300-8837.

Thanks,
Danny

 It's a flat screen LCD... besides, there are no magnets anywhere near.  And lets not forget that the Splash screen displays fine with full brightness until the Home Screen comes up.  That's when the right side goes dim.

A hardware issue that doesn't effect the splash screen and sometimes goes away?  That doesn't sound plausible, although I suppose anything is possible.

Hi. I have the same problem, same side of the screen.  I contacted TCL through their chat and we spent at least a half hour trying to troubleshoot and fix the issue, with no success.  They were supposed to send me an email so I could send over a picture of the TV screen and I never got one, so I'm here to see if anyone has any clue as to how to fix this.

I just unplugged it for about 20 seconds and it fixed it. Still has me uneasy though, I've only had this TV for 3 years I shouldn't be having problems with it

The exact same thing started happening on mine at 1 1/2 years.  I actually tried everything possible to fix.  Nothing.  Gets worse every time I turn it on.  I actually unplugged it for the past 6 months.  I am moving soon and packing up all my stuff.  My good tvs are moving to new place ahead of me.  I plugged in this ridiculously poor quality tcl just to get me through the next 5 weeks.  Not even sure it will last that long before it becomes completely unwatchable.  I am going to toss it and just go back to my dependable Samsung and consider it a lesson learned.  Will never buy a Tcl again. 
Roku should definitely reconsider who they partner with in the future.

The right side of my 43S403 TCL/Roku TV has the same dimmer right side issue.  I did do all the suggested fixes but non worked. The only thing TCL tech support said to me is that because my purchase year is 2017,  I don't have warranty coverage.  Looking at the multiple online posts, such as this one, I'm wondering if this is a widespread hardware problem?  I've had several different brand flat screen tvs over the years and this is the first problem I've encountered.

I'm having the same issue. It has gotten progressively worse and now the whole screen just dims almost like it's flashing to the point where it's not usable when it starts doing it. Disconnecting the power source fixes it sometimes but not every time.
