Introdução
This guide explains the replacement of the LED display for the Health o Meter HDR743 digital bathroom scale. The LED display shows the weight in lbs. in red numbers with a capacity of 350lbs. If the red numbers are not visible, clear, or crisp, then the LED display may need to be replaced.
O que você precisa
-
-
Open front cover of scale.
-
Examine the edges of the LED display to see if there are broken or missing solder connections with the circuit board.
-
-
-
Use a soldering iron to separate each of the connections between the circuit board and LED display. Once all of the connections are removed, pull away the broken LED display from the circuit board.
-
Remove unnecessary solder from the old connections so that each connection is separate. Leave a small amount of solder on the board to help make new connections.

Once reassembled and tested, if the new LED display does not work and no connection issues are seen, then it may be the circuit board. In that case, see Circuit Board Replacement.
