ᐅ TV backlight USB automatically turns on when powered on

Hello everyone,
I am looking for the following solution:
An LED strip for the TV should be connected to the TV’s USB port and the strip should light up when the TV is turned on. So, no extra remote control or anything like that.
What should I pay attention to?

I assume that common LED strips with a remote control need to be switched on separately using the remote, right?
Thank you.

You can also do this yourself with a suitable power supply; the LEDs don’t mind. The power just needs to be appropriate. Many LED strips with remote controls simply return to the last setting when powered on, so at least the control can be retained. Another potential issue is that the USB port might not be powered off when the TV is in standby mode. Test this beforehand.

Or you can use the Philips Hue Ambient Light Strip and the Hue Sync Box.

This way, you effectively retrofit a true Ambilight system.

The colors of the backlighting match the TV picture.

At those prices, you might as well consider a Philips TV with Ambilight.

The LED strips might sometimes draw more current than the USB port can supply. I would recommend using an external power supply.

I had the same setup with my Panasonic LED once. The LED light became a bit dimmer, and the TV occasionally had issues powering the LEDs. It might be better to opt for an external power solution. Check how many milliamps (mA) the USB port provides...

What kind of LED strip is this? The power from the TV might not be enough.

If you want a simple solution, I would suggest using a master-slave power strip. The TV acts as the master, and when the current increases beyond a certain threshold (TV switching from standby to on), the slave sockets turn on. You can then plug the LED power supply into one of the slave sockets – along with any other devices that should only operate when the TV is on.
