Can anyone tell me what the small black component (circled in blue on the photo below), just below the backlight fuse (red arrow) is?

Also does anyone know what the small IC with six legs just to the left of the backlight fuse is?

Thanks in advance.

Is this a good question?

@ddebbil the part circled in blue is R4272 which is a 1K 1/16W 5% resistor in a 0402 package

Use Kapton tape while trying to solder to keep nearby components from getting damaged.

The “IC” is a Q9807 which is a SSM6N15FEAPE Silicon N Channel MOS Type transistor in a SOT563 package.
