TCL TV pairs and works, then stops responding — what to check

In short

When a TCL TV works right after setup and then goes quiet, it's almost always one of three things: the TV's IP address changed, the TV shut down its network-control service in standby, or the TV was added under the wrong TCL integration — TCL ships both Roku-based and Google TV models, and they use completely different control methods.

First: which kind of TCL do you have?

TCL sells Roku TVs (common in North America) and Google TV models (common in the UK and Europe). Roku-based sets add without any pairing step; Google TV models show a pairing code. If your TV asked you to pair, it's a Google TV — make sure you added it as an Android TV device, not under the TCL/Roku entry. Picking the wrong one can appear to work briefly and then fail.

Give the TV a fixed address

If the TV's DHCP lease renews and its IP address changes, Roomie keeps sending commands to the old address. Reserve a static IP for the TV in your router's DHCP settings — this is the single most common cause of "worked yesterday, dead today" for network-controlled devices.

Keep the control service awake

Many TVs power down their network interface in standby. In the TV's network settings, enable the option variously named Network Standby, Wake on LAN, or "control by mobile apps" so the TV keeps listening while off.

Still stuck?

Reproduce the failure, then use Send Diagnostics in Roomie's settings. The log shows immediately whether commands are going to a stale address, the TV is refusing connections, or the wrong integration is engaging.
