  If your Welch Allyn Scales aren't turning on, here are a few things to check: * **Dead Batteries or no rear Adapter:** Ensure that the batteries are not dead. Replace them with fresh Alkaline “C” Cells. * **Faceplate:** Remove the front panel and verify that the Black and Red cable connector is securely in place. If not, replace either the switch assembly or the Battery Holder Assembly. * **Cracked Battery Holder:** Examine the battery holder for any cracks. * **Display Board/Main board:** If the above steps don't resolve the issue, the Display Board/Main board might be faulty and need replacement.

  If you notice missing segments in the numbers displayed on your Welch Allyn Scales, it could be due to: * **LED:** Remove the Display Board. Gently lift a working 7 Segment LED chip with a flat head screwdriver and exchange it with a non-working LED chip. If the issue follows the LED chip, replace the chip. If the problem remains in the same socket, replace the display board. * **Display Board:** The display board itself might be faulty and require replacement. * **Main Board:** In some cases, the main board could be the cause, necessitating its replacement.

  If your Welch Allyn Scales are only showing the model number, this could indicate a problem with the A/D Chip. Specifically, the U10 Microprocessor might not be communicating with U6. Check that the U6 and U10 chips are properly seated. If the issue persists, consider replacing the Main Board.
