Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: 55/65/75/85R655
What that covers: TCL TV; Roku TV, Google TV and Fire TV platforms use different menus and app stores.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Panel — Mini-LED QLED: The 6-Series R655 is a Mini-LED QLED with strong local dimming — a backlight, so some blooming is normal, but well controlled. A capable picture from an earlier TCL generation.
Smart platform — ROKU TV (not Google TV): The R655 runs Roku OS built in, NOT Google TV. Update at Settings › System › System update; screen mirroring is Miracast and AirPlay 2; the remote and app store are Roku's. Google-TV instructions do not apply — this is the key difference from TCL's Q-series and the R646.
Gaming / HDMI: A 120 Hz panel with HDMI 2.1 supporting 4K 120 Hz, VRR and ALLM. Enable Game Mode / Auto Low Latency. Supports Dolby Vision, HDR10 and HLG.

Exact questions

Questions that only have an answer for the TCL 6-Series Roku TV R655

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

Is my TCL 6-Series R655 a Roku TV?+

Yes. The 6-Series R655 has Roku OS built in, so it updates and installs apps through Roku (Settings › System › System update), uses a Roku remote, and mirrors via Miracast/AirPlay 2. This is different from TCL's newer Q7/QM7/QM8 and the 6-Series R646, which are Google TVs — so use Roku-TV steps for the R655, not Google-TV ones.

Structured depth, not empty permutations
