The IMac is the smartest Macintosh that Apple has released to date. Being super-fast, efficient and heavy on performance, the IMac would truly be one of the greatest things Apple has made if only the bugs didn’t show up in it. Although it isn’t common, many IMac users come across this use where they have a black screen on startup along with a chime.
You can take your Mac to your nearest Apple service center but we have mentioned several solutions by which you can solve the black screen on startup with a chime issue. Make sure to follow these steps correctly and you might end up solving this issue for good. The Macbook and Macbook air won’t be discussed here since we are only going to talk about the IMac.
Let us begin with the ways you can solve this display issue on your Apple computer.
Solutions To Fix iMac Black Screen on Startup with Chime
Troubleshoot with Power Button
The IMac black screen on startup with chime issue can be fixed with the power button of your system. When you use the power button in a specific manner then you can troubleshoot this problem. Follow these steps for the correct troubleshooting:
- Close all active applications on your IMac
- Shot down the IMac from desktop
- Turn the Power Button On
- Keep it Pressed for twenty seconds
- Release the power button
- Wait for thirty seconds
- Turn on the IMac like you would do normally
If somehow this solution isn’t the answer to your problem and the black screen persists, then you can move on to the next solution.
Increase Brightness on Your IMac
This solution might be a pretty dumb one to try but that doesn’t mean you shouldn’t. The IMac black screen on startup with chime can be fixed by increasing the brightness of your screen. Sometimes, the brightness level can be lowered due to other users using the IMac or due to loss of touch in the brightness controls.
In this case, increasing the brightness of your system can bring back a more visible display on your screen. To adjust the brightness settings in your MacOS, follow these steps:
- Hold down the function key
- Then press the brightness key
Another way do it is this way:
- Click on the Apple Menu
- Go to System Preferences
- Choose the Display Option Under System Preferences
- Use the Contrast Slider to Adjust the Screen’s Brightness
If this solution doesn’t fix your issue either then move on to the next one.
Reset the RAM
You will need to reset the RAM on your IMac to fix the IMac black screen no chime problem. This step is only advised if you’re an advanced Mac user. If you are experienced enough in related troubleshooting methods only then try it. You will just need to reset the ram once. If it isn’t done correctly then the memory could be wiped off of your entire system.
You will need to take out your RAM from the slot and clean it with rubbing alcohol. Let it dry for some time before you install it back in the slot. Make sure to take it out carefully as you will need to release the latches on the side of the RAM slot with care by making sure you don’t hit any sides of the system especially the fans.
Fixing the Graphics Card
The graphic card enhances the display of your IMac but any issues with the graphics card can cause the black screen issue on it. The graphics card can get loose or its port may need to be fixed. If the graphics card is causing the iMac black screen display issue then you can follow these steps to fix this issue:
- Make Sure The Cable Is Properly Connected To The Port
- Clean The Graphics Card Connecting Port With Cotton Dipped In Alcohol
- Remove the Graphics Card and run your IMac and then shut your system down
- Reinsert the Graphics Card
- Run a hardware test by rebooting the IMac and pressing down the R key when the system boots up again
A hardware test automatically diagnoses and fixes any issues relating to the IMac’s hardware. If your problem still isn’t fixed then you will need to move to the next passage in this article for further help.
If none of the methods that have been told by us work so far and you are sure that your display has no kind of internal hardware issues then there must be an issue with your operating system. You will then have to reinstall the MacOS on your operating system and this is the last option you can carry out by yourself to fix this black screen issue.
