LCD Module Replacement: CrystalFontz 632 16X2 LCD Module

Supported Program: FrontView for MCE & Third Parties


Due to the sensitive paint on the HTPC 100 front bezel, please pay detail attention and do your best to avoid scratches during the assembling. It is end user's full responsibility to protect the surface while changing the module.

For more information regarding the CrystalFontz module and the MCE support program that can program module, please visit their websites for details.

Q: How do I replace the LCD with CrystalFontZ programmable LCD?

A: Here are the instructions.

  • Remove the MCE Rack from inside, (under the Optical drive) remove the 2 screws that holding the panel

  • Disconnect all cables that are coming from the LCD module, like CPU sensor, 12V connector, CPU fan...

  • There are six taps that holding the panel, they are tiny plastic, so be very careful. Push up the two three, slide down the panel 30 degree, and remove the panel from the bottom 3 taps. Make sure you loose all cables and make sure they are long enough to allow your panel slide flat on your table with protector stuff to avoid scratch.

  • Take the LCD and all cables out, install the CrystalFontz LCD module, connect the USB cable

  • Re-install the panel. Put your system 90 degree upward, match the bottom 3 taps, and push the panel down and slide the panel in with the top 3 taps. Done!

  • If you break the taps somehow, it is still fine, your two screws can still hold the panel firm. But, that is the plan B, I hope you will be fine.

Q: How do I place the CPU & Case temperature sensors?

A: It is up to you to place the case temperature sensor anywhere you want, or any place that you concern about the heat. For the CPU temperature sensor, normally, place it between the CPU cooler and the CPU, or place it between the CPU cooler fins. Button line, any where or any way that you can stick the sensor to the cooler or CPU to measure the temperature accurately.

Q: If I am not planning to use the front CPU fan speed controller, can I just connect the CPU fan connector directly to the MB?

A: Sure. If you are not comfortable to have the LCD to control the heatsink fan spped, just connect the fan to motherboard directly.

Q: When I press the "Reset" button to try to re-start the system, nothing happen, only the LCD got reset, is it right?

A: Yes, the "reset" button is for the LCD only. You can use the "Power" button to re-start the system.
