[Sonic Mega 8K S] Checking the Touch Panel

Is the touch panel of your Sonic Mega 8K S behaving strangely? Has it become unresponsive, fully dark or white, etc.?

Thus, before asking for external support or installing a new touch panel for your Sonic Mega 8K S, you can take some easy troubleshooting steps by yourself.

Do not worry because this article will provide you with a detailed and simple guide on how to reseat the touch panel cable as well as update the latest firmware. These steps may help to resolve the touch panel-related issues and your printer can get back to normal.

1. Reconnect the Touch Panel Cable

Always disconnect the power source before disassembling any electrical equipment. If it is necessary to handle equipment that is still plugged in, ensure your hands are dry and consider wearing insulation gloves, protective clothing, and shoes with insulated soles if possible.

One of the first things to check is the touch panel ribbon cable which may have become loose or disconnected over time. 

Power down and prepare

• Use an Allen Wrench (Size 2) to loosen the 12 screws and open the front case

Identify and reconnect the Touch Panel cable

• Locate the white ribbon cable connecting to the mainboard and the touch panel
• Reconnect both ends of the touch panel cable and make sure the blue mark is facing upwards

Reassemble the printer

• Use an Allen Wrench (Size 2) to tighten the 12 screws on the front case 

Verify the Touch Panel’s functionality

• Plug in the power cord and turn on the printer
• Verify if the touch panel is working properly

2. Updating Firmware

Reflashing the latest firmware can solve touch panel issues caused by outdated software conflicts.

By doing so, you can make sure the printer's software is fully compatible with the touch panel, which can help to prevent issues such as unresponsiveness or erratic behavior.
