Tcl roku 55 inch smart tv

Thank you. Offhand these symptoms directly indicate a premature hardware failure in the set (not uncommon with off brands like TCL, Haier, etc.), and in most cases require service.

However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.

The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.

It did not work, the screen goes from black to blue then shuts off again

I'm sorry and that is all you can try on a user level. The TV is faulty and requires repairs. Given it's under a year old you would need to contact TCL regarding warranty repairs on the set.

Other than that, I'm sorry for the bad news here and wish there were a quick fix.
If you need further assistance let me know. Before you go, PLEASE DO click at least a 3 STAR RATING, at the top of your screen. That is how I am credited for my efforts by the site.
