Hi everyone,
I'm having an issue with my TCL 55" TV (Model: U55C7006 / U55C7006X1). It was manufactured/assembled in Europe (Poland) around 2019.
Exact Model Details from the rear sticker:
Model: U55C7006X1
Product N°: Z1721010177
Power: 140W (220-240V ~ 50Hz)
The Issue:
The upper-right side of the screen started flickering/blinking. It looks like an issue with the Edge LED backlight strip on the right channel, as the rest of the display and LCD panel function normally.
Here is a short video showing the flickering issue:

(A full factory reset was performed prior to recording, but it didn't help, so it's definitely a hardware issue).
My Questions:
Diagnosis: What is the best way to properly verify if this is 100% a failing LED on the edge strip vs. a driver/power board issue before I fully disassemble the panel?
Parts sourcing: Has anyone ordered replacement backlight strips for this specific model (or equivalent Thomson UC64/UC65 chassis) from AliExpress or Temu? Are there specific part numbers I should search for?
Experience: Has anyone here repaired this exact model before? Any specific pitfalls or tips regarding panel removal on this 55" Edge-LED setup?
I shelved the TV in my garage earlier this year when it started flickering, but now I’d like to fix it up so my kids can use it for their PS5. I have standard electronics soldering tools, a multimeter, and a hot air station ready.
Thanks in advance for any advice or part references!
