Any solution for black screen occurs sometime when a electrical house appliance hair dryer, stand fan, etc turned on or a lightning strike. It will back to normal after couple of seconds.

    This could be an issue with power surges  or electrical interference's. These surges can occur when large appliances, like air conditioners and refrigerators, are turned on and off. Even smaller devices, such as a hair dryer, can cause a surge of five to 10 volts when turned on.
    It’s easy to pick surge protectors based on the number of outlets or a snazzy design. But without reliable protection, all you have is a power strip. A power strip only offers more outlets, while a surge protector is first and foremost a safety device that just happens to have extra outlets too. This way, you know your devices are protected so long as they’re functioning.

    Even better would be a UPS. They typically have the same surge protection and also let you shutdown safely when there has been a power interruption.
