chromebook screen blinks on certain apps

[Dan197]

We have not had chromebook for long. Whilst using some apps like show my homework, youtube  and powerpoint the screen will occasionally blink black more irritating than anything. The laptop is not being touched and will just happen. We have another chromebook also a HP and we do not get the same problem. We get no error messages and when it returns to the screen it continues as normal.  I have watched screen when on the home screen and this does not seem to happen. Any ideas?

I reviewed your post and I understand that the display flickers in some applications.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you follow the below steps and check if it helps.

Step 1: Remove external devices

If the Chromebook does not start, remove any USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices including external hard drives and other similar devices.

After you have removed all external devices, turn on the Chromebook.

• If the computer starts, reconnect devices one at a time, and restart the Chromebook each time you connect another device to figure out which device is causing the problem. You are done.

• If the unit still does not start or exhibits the same problem, go to the next step to perform a hard reset.

Step 2: Perform a hard reset

A hard or forced reset erases all information in the computer memory. This forces the system to clear and reestablish the software connections between the BIOS and the hardware.

A hard reset does not remove any local files or settings.

1. Press the power button  and refresh  button for five seconds. The computer turns off, and then turns on again.

2. If necessary, press power button again to turn on the laptop.

3. If the issue persists, continue to the next step.

Step 3: Perform a system recovery

A system recovery completely erases any local files or settings and returns the computer to its original factory-shipped state.

• If a hard reset does not resolve your issue OR your Chromebook shows the error message Chrome OS is missing or damaged, you might need to perform a system recovery. For detailed instructions go to Chromebook Help Center and search for Recover your Chromebook.

  

Let me know how it goes and you have a great day!
