Problems with the lamp Yeelight LED Crystal Ceiling Lamp Pro

Good afternoon
Please advise on a problem with a previously purchased Yeelight LED Crystal Ceiling Lamp Pro.
Purchased through the Yandex Market service, the screen is in the attachment.
The problem is expressed as follows, when turned on, the lamp arbitrarily changes the brightness / color, for some time it works stably, then it arbitrarily turns off or changes the brightness / color.
The remote control, with the advent of the problem, lost its binding.
What to do?

Please check if the LAN CONTROL function is enabled. If it is, turn it off and see if the same problem still persists.
