TCL 55-inch Q Class Q651G 4K UHD HDR QLED Google TV

Model details

Additional useful information

Use this source-reviewed TCL 55Q651G guide to set up Google TV, recover from common picture or audio problems, and evaluate cables, remotes, stands, antennas and mounts without assuming cross-size compatibility.

A verified U.S. Q651G replacement with a sixty-hertz panel and unusually mixed wall-screw lengths. This U.S. Q651G replacement occupies the invalid 55S5K slot and changes both platform evidence and physical fit: it is a four-K QLED with a 300-by-300 wall pattern. Display evidence: QLED PRO with a 3840 x 2160 4K panel; 60 Hz panel with Motion Rate 240 and MEMC. HDR PRO+ with Dolby Vision, HDR10+, HDR10 and HLG. Connection evidence: three HDMI inputs including one eARC, plus Ethernet, one USB 2.0 and optical digital audio. For first use, install the exact stand hardware or verified bracket, connect power and sources, and complete the on-screen language, network and Google TV choices. U.S. smart features need internet service and a Google account; antenna or cable users should select the U.S. broadcast source and run a channel scan. If settings or apps remain unstable after a normal restart and software update, use Settings > System > About > Factory reset and follow the prompts. A factory reset removes local accounts, apps, networks and preferences, so record picture, audio and accessibility choices before using it. For no picture, confirm power, select the numbered input actually carrying the source, reseat both HDMI ends and test a known-good source at a supported mode. For external-audio silence, follow this connection boundary: Use the one HDMI jack physically labeled eARC; the reviewed specification does not publish its number. Then select the intended audio output and confirm HDMI control/CEC where the guide requires it. Power-cycle the television and connected device before escalating to reset. 55Q651G is documented at 300 x 300 mm, 23.2 lb without stand, using M6 x 30 mm top and M6 x 16 mm bottom. These values come from TCL USA exact product specification; bracket load rating, wall construction, spacers, effective engagement, access and ventilation still control the installation. Remote replacement remains evidence-driven: included Google TV Voice Remote with two AAA batteries; no replacement part number is asserted. Stand parts must name the full 55Q651G, because feet, pedestals and screws are not transferable merely because another set shares the Q651G name. Broadcast setup is also region-scoped: ATSC, NTSC and Clear QAM for the U.S. model.
