  If the entire Absen Monitor screen is black, first verify that the screen power is turned on. Then, check if the DVI or HDMI cable is properly connected and not loose. Also, ensure that the main data cable is well inserted. Check that the sending card is powered on and that its running indicator is flashing. If these steps don't resolve the issue, try connecting the computer to an LCD display to check the video card output, update the video card driver, or consider replacing the sending card or the computer.

  Danny DickersonAug 16, 2025
  If some modules on your Absen Monitor are black, start by checking if the power plug of the affected module is tightly inserted. Also, inspect the power cable for any signs of burning. Verify that the switch power supply of the module is outputting power and that the flat cable is functioning correctly. If issues persist, try replacing the flat cable, the module itself, or the receiving card. Sending the rcfg file might also help.

The Absen New HC Series is a high-definition, small-pitch LED display screen specifically designed for control rooms, meeting rooms, and high-end business displays. The cabinet measures 600x337.5mm, designed in a 27-inch 16:9 ratio, and offers various pixel pitches including P1.5, P1.2, P0.9, and P0.7 to ensure detailed image display.

Function Description:

The HC Series products are primarily used in professional control rooms, meeting rooms, and high-end business display environments. They are designed to provide high-quality visual output for critical applications where image detail and reliability are paramount. The display cannot store or display video content independently; it requires a video source from an output device such as a PC, laptop, or media player, and one or more sending boxes to receive and feed the source.

Important Technical Specifications:

The New HC Series includes five product variations: HC0.7 Pro II, HC0.9 Pro II, HC1.2 Pro II, HC1.2 II, and HC1.5 II.

LED Type: HC1.2 II and HC1.5 II utilize traditional 3-in-1 SMD surface patch technology, while HC0.7 Pro II, HC0.9 Pro II, and HC1.2 Pro II feature 4-in-1 integrated encapsulation.
Pixel Pitch (mm): Ranges from 0.78 (HC0.7 Pro II) to 1.56 (HC1.5 II).
Panel Dimensions (WxHxD): All models share a consistent cabinet size of 600x337.5x50mm.
Pixel Per Panel: Varies by model, e.g., 768x432 for HC0.7 Pro II, 384x216 for HC1.5 II.
Panel Weight (kg): Approximately 5.2 to 5.9 kg, with all panels made of Al Die-Casting.
Module Dimensions (WxH): 150 x 168.75mm for HC0.7 Pro II and HC0.9 Pro II; 150 x 337.5mm for HC1.2 Pro II, HC1.2 II, and HC1.5 II.
Brightness (nit): All models offer a brightness of 600 nit.
Refresh Rate (Hz): Ranges from 2880 Hz (HC0.9 Pro II) to 3840 Hz for other models.

Maintenance Features:

Full Front Maintenance: Modules, power supplies, receiving cards, and HUBs can all be maintained from the front.
Preparation Tools: Includes a module front service tool, PH2 cross screwdriver, PH00 cross screwdriver, and a multimeter.
Module Maintenance:
- Use the front service tool to suck out the module by pressing its button. Hold the module by hand and release the button to remove it.
- For HC0.7 Pro II and HC0.9 Pro II (small PCB), a dedicated small PCB module maintenance tool is required.
- When removing a module, ensure the tool is placed in the middle of a single module and does not cross over to adjacent modules.
- Hold the module with your hand to prevent it from falling due to low power or accidental startup of the maintenance tool.
- New modules are installed by gently placing them in the upward direction onto the cabinet.
HUB Board/Receiving Card/Power Supply Maintenance:
- First, remove all modules on the faulty cabinet using a vacuum maintenance tool.
- Use a PH2 cross screwdriver to remove 12 screws from the HUB.
- Remove the power supply and network cable from the HUB, then remove the HUB itself.
- For receiving card replacement, use a PH2 cross screwdriver to remove two screws fixing the receiving card.
- For power supply replacement, use a PH2 cross screwdriver to remove the PM3 round head screw, remove the black insulation, and then use a PH00 cross screwdriver to remove the PM2 round head screw fixing the power supply.
Troubleshooting: The manual provides a comprehensive troubleshooting guide for common faults such as black modules, a completely black screen, scrambled images, chromatic aberration between modules, and all panels displaying the same content. Solutions range from checking cable connections and power supply to replacing components like modules, receiving cards, sending cards, or updating firmware/drivers.
Safety Check: Before operation, always use a multimeter to check for short circuits at the AC input (L/N/PE) and DC output (VCC/GND) of the power supply after cabinet wiring. Ensure all wirings are normal before connecting power.
