If your LG OLED TV freezes and turns off, with the screen turning white or green and a high-pitched noise, it could be due to a variety of reasons, including:

1. Software update issue: Check for any available software updates for your LG OLED TV, and update the firmware to the latest version to resolve any bugs or issues that may be causing the freezing and turning off.
2. Overheating: Overheating can cause your LG OLED TV to freeze and turn off. Ensure that the TV is well-ventilated and there is enough space for air to circulate around it. You can also consider installing a fan or cooling pad to help prevent overheating.
3. Power supply issue: A faulty power supply can also cause the TV to freeze and turn off. Check the power cable and ensure it is plugged in properly, and that the power outlet is functioning properly. You can also try plugging the TV into a different outlet to see if that resolves the issue.
4. Hardware issue: If the issue persists, it could be due to a hardware problem, such as a defective circuit board, a damaged capacitor, or a faulty display panel. In such cases, it is recommended to contact LG support or a professional repair technician to diagnose and fix the issue.

It is important to identify the cause of the issue and resolve it as soon as possible to prevent further damage to the TV.

" 42" OLED " is merely a description of size and screen display type, it's not a model number. If it is this set, it has Bluetooth Support, a different model may not.

Samsung is the sole supplier of the iPhone X's OLED screen, letting Apple finally start moving away from LCD screens. I'm referring to the fact that all the great new iPhone X features are already available in many Android phones, and Samsung is the one that has pushed them to the forefront.
But yes, the edge-to-edge screen is worth calling out first. Samsung is the king of smartphone screens. There's a reason Apple had to tap its rival as a supplier for the iPhone X. And yet it's Samsung that has made edge-to-edge screens popular this year with the Galaxy S8, Galaxy S8+, and Galaxy Note8, all which sport beautiful screens with higher resolutions and pixel densities than the iPhone X's.

When ”high temperature” shows on the OLED screen, the device is too hot, so place it in a cool, ventilated location. When the temperature is high enough, the device will stop charging/functioning in order to avoid damage.

This device responds to overheating whether or not it is charging.

When the device is charging:
• The device is powered on. When the temperature is higher than 113°F/45°C but lower than 140°F/60°C, it will not show “high temperature” but it will stop charging.
• The device is powered on. When the temperature is higher than 140°F/60°C, it will power off & stop charging. Also the OLED screen will show ”high temperature” at that time.
• The device is powered off. When the temperature is higher than 113°F/45°C, it will stop charging & the OLED screen will show ”high temperature."

When the device isn’t charging:
• Only when the temperature is higher than 140°F/60°C, will the OLED screen show “high temperature” & this device will power off.

you need to check the nuetral safety wire. It is black with a white stripe.

its always best to call the manufacturer of any device that is not
working properly chances are they will have replacement parts
or remedies for their products , when you talk about replacement
parts you mean soldering components to a main board which was
probably manufactured under a magnifying lens by a robotic
assembler .
