Follow these steps to troubleshoot why the monitor power light is blinking and there is no picture.
IMPORTANT: This article applies only to specific products and/or operating systems. Check the Applicable Products and Categories section of this article before starting these steps.
- Because each of these steps represents a possible solution to this issue, check the monitor status after completing each step.
- If model-specific information is required to complete any of the steps in this solution, refer to the operating instructions supplied with the product. Manuals are posted on your model support page.
- Disconnect the monitor power plug, wait a few minutes, and then reconnect.
- Remove the monitor power plug from any surge protector or power strip and plug it directly into a known working electrical wall outlet.
NOTE: If the monitor works correctly when removed from a surge protector or power strip and plugged directly into a known working electrical wall outlet, the source of the issue is the surge protector or power strip.
- Disconnect the monitor data cable from the computer, check for bent or broken pins.
- Perform a monitor self-test.
NOTE: If the monitor self-test fails, the monitor may need service.
- If possible, connect the monitor to another computer.
- If the monitor works on another computer, there is a problem with the original computer video hardware or software display settings.
- Some software, particularly games, allow for configuration of monitor settings such as screen size. Incorrect settings can cause the monitor lights to blink and the screen to be blank.
