2018 Model TCL 43” 4K 43s517 has been flickering and jumps like the old tv with the vertical hold adjustments. I have did a factory reset and reload all my channels and it still does the same thing. When I first turn on the third ok but as time goes on it flickers in the middle enough to notice and then not to long later it starts to jump like a double image every set or so. I have a blue ray player an Amazon diet stick and an Xbox one system. I have unplugged them all From the HDMI PORTS and it still does the same. Anyone experienced the same problem?
I have researched it all.
TIA for looking here
Mine is doing the same exact thing, and I have the same model as you. From what I've read it might be an issue with the T-con board, so I just ordered one off eBay to see if that solves the problem. I'll update when I do.
Hey cool thanks! There is only like 3 main components the main board t-con board and power supply! I’m able to view it for many hours with all the HDMI unplugged. I really want to use my blu ray with the surround sound Hooked up and the optical cable plugged in. This is why I think it might be the main board but I’m know Tv repair guy. Also it jumps with my Xbox plugged in. There is a YouTube video on replacing all the boards. Seems easy enough!
thanks for the reply and good luck with repair.
Hey just an update, I replaced my t-con board and it didn't help at all lol. Did you have any luck?

Herman Hi
wow sorry that didn’t work! I ordered a main board from eBay! $23 plus $10 shipping.I haven’t had time to install it. I’m off work Wednesday and as soon as I install and plug everything back in and test I’ll give you a shout on here ASAP.
Herman I have had my TV on mute all day with my Amazon fire stick my surround sound and my aquarium 4 K screensaver all day long. there is no more Flickering or jumping on the screen so I noticed that one small plug was crooked and that might’ve been the problem the whole time so I just ended up replacing the Main board since I had it open I’m enclosing a picture of what the plug looks like.
hope this helps you
Ok cool, thanks for the update. the main board I ordered is coming in the mail tomorrow so hopefully that works!
Good! Just be careful with the black ribbon cable! It’s real tender! Hope it works for you!
Herman
any luck with the main board?
It actually didn't make any difference at all, it's still doing the same exact thing 😞
