LED doesn’t light up or flicker or do anything at all. I have no FireWire ports on my Laptop so i can’t try out the FireWire capabilities. I tried the USB connector and Windows detects it as „generic USB Hub“ but doesn’t detect USB devices or flash drives plugged into the monitor. I don’t have a DVI port and I ordered an adapter so I can’t test connectivity yet. Does it need a video signal to turn on? I’ve been holding down the touch power button, Double and triple pressing it - no avail. am i doing something wrong?

Hi, Gregor. Don’t worry, people here are all wrong. My Cinema Display 30-inch says “Cinema HD Display” on its aluminium frame. And yes, you need 5V power from Pin 14 of DVI connector to turn it on. I hope this could help you. Thanks.

@gammanumeric the Apple Cinema HD display should work on any system that has a DVI-D port. For the 30" and the 27" you will need a dual-link DVI-D port to be able to use the full resolution. You may run into some issues like not having full capable resolution, brightness control etc. since you will need an appropriate driver for this monitor, but it should not prevent your monitor from at least turning on. Power Power switch or brightness button not working 2. Check connector J4 at the main board. Reseat the cable at the main board and at the touch switch board. 3. Replace the touch switch cable. 4. Replace the right end cap that includes the touch switch board. No power

  1. Check the wattage that is printed on the power adapter. See the table below to verify that the power adapter shows the correct power rating for this display. (For more information, refer to Knowledge Base article 86800.)
  2. Use a known-good power adapter, and check all cable connections. Let us know what you find on your power adapter and let us know once you get your DVI setup. Update (10/13/2019)

What I found worked is unplugging the USB that goes into the power brick.

Try unplugging the USB on the power brick. It was messing mine up.

Are you sure you have a Cinema HD display? This display uses an old connector ADC (Apple Display Connector). You’ll need to convert it to DVI and then you’ll need to convert this one more time to DP (DisplayPort or mini DisplayPort) depending on what your PC’s graphics board supports. By the time to get all of the needed adapters to get the signal converted, I think you can buy a better display for less. Besides we still don’t know if this display is even working.
