Often, a residual electrical charge or a temporary software loop causes this error. A complete power cycle can clear it.
If the machine intermittently boots or allows access to the web image monitor via a web browser, update the system firmware immediately.
Install a known working operation panel assembly from an identical model. If the error clears, replace the original panel.
When you turn on the machine, the controller board and the operation panel exchange a "handshake" signal. If the controller board does not receive a response from the panel within a specific timeframe (usually 15 to 30 seconds), the system triggers this error to protect the hardware.

Note: This step requires removing access panels. If the machine is under lease or warranty, contact your service provider first. Turn off the machine and unplug the power cord.
To minimize the chances of the SC673-10 error returning in the future:
When you switch the machine on, the controller board executes a boot sequence and ping-tests all connected peripherals. If the operation panel remains unresponsive during this boot window, the machine halts and displays the SC673-10 code. Primary Causes of the SC673-10 Error Often, a residual electrical charge or a temporary
A known issue where the error triggers during normal operation or after waking from sleep mode.
Several factors can disrupt communication between the controller board and the operation panel: 1. Loose or Damaged USB/Harness Cables
Turn off the (usually located inside the front door or on the side). Unplug the power cord from the wall outlet. Install a known working operation panel assembly from
Locate the matching input port for the panel interface cables and ensure it is snug and secure. 4. Execute an SC Reset Command
This SC code is issued for devices that have a Smart Operation Panel installed and is not triggered on models with a conventional keypad screen.
Load the firmware files onto an SD card or USB drive formatting to FAT32.
: A hardware failure on the controller board can stop it from talking to peripheral parts. 📋 How to Troubleshoot and Fix SC673-10
