ALT A mobile radio is laying on a blue ifixit repair mat along with some screws and a pen. The radio's top cover is removed, exposing the complex internal circuit board.
ALT Close up photo of the corner of a green circuit board. In the center is a larger rectangular component with what looks to be moisture blobs on its surface.
ALT A close up photo of the corner of the same circuit board with the black rectangular component replaces with a new, clean one. The component marking is M50FWL.
ALT The black rectangular component is shown cut apart with a dozen pieces laying on a white lab bench surface. Various pieces look clean and untarnished. But two of the pieces are clearly blue with corrosion.
ALT The background of space is black. Thousands of galaxies appear all across the view. Their shapes and colors vary. Some are various shades of orange, others are white. Most stars appear blue, and are sometimes as large as more distant galaxies that appear next to them. A very bright star is just above and left of center. It has eight bright blue, long diffraction spikes. Between 4 o’clock and 6 o’clock in its spikes are several very bright galaxies. A group of three are in the middle, and two are closer to 4 o’clock. These galaxies are part of the galaxy cluster SMACS 0723, and they are warping the appearances of galaxies seen around them. Long orange arcs appear at left and right toward the center.
