Horizontal Line

I have a 49S405-B TCL Roku TV and there is a light horizontal line repeatedly going up the screen. This line only appears on HDMI inputs, and not the built in apps. Its only visible on dark parts of the screen. It also does not go all the way up the screen. It starts in the middle, slowly makes it way to the top, and then appears in the middle again to start again. 

I have tried different HDMI ports, different HDMI devices, and changing brightness settings to hide it with no success. I didn't notice it until the TV was out of warranty.

Re: Horizontal Line

@Casper5632 

Thanks for the post.

Have you tried switching out the HDMI cable used to connect your device?

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

Re: Horizontal Line

I have tried contacting them, but they just suggested I try stuff I had already tried. I have had many HDMI cables plugged into this TV. It only has HDMI and A/V, and I don't have any way to test the A/V to see if it happens for all inputs.

Re: Horizontal Line

I have the same problem with mine, no amount of cable switching or anyhting will fix it.  Putting the tv into game mode makes it way less noticeable.  roku sucks for this they don't even care.

Re: Horizontal Line

You're right: they don't care.  Last night, Juan from Roku "customer service" (ha) had me plug and unplug my Roku and TV.   When that didn't solve the problem, he said it was either an internet or TV issue.  I spent over an hour with my internet provider, who tested speed, upload, bandwidth, etc., and said everything is fine.   I spent another hour+ today with Sharp TV, who said it is a Roku problem.  So back to phoning Roku, who said that without a cell phone with data (I don't have) or another TV (I don't have) or cable/satellite TV (I don't have), they can't check if it is the Roku.  At least Carlos today had me doing resets and restarts, which Juan last night couldn't be bothered with.   So I'm left with no TV for the next several months.  Thanks for nothing, Roku.  Sorry I bought your **bleep** equipment a few months ago.
