Troubleshooting Horizontal Lines on Your Acer Aspire All-in-One Screen

If you’re facing the frustrating issue of intermittent horizontal lines appearing on your Acer Aspire All-in-One display after a recent glass replacement, you’re not alone. A fellow tech enthusiast recently encountered a similar dilemma and shared their experience, prompting a discussion on how to effectively diagnose such hardware problems.

Initial Diagnosis

After replacing the glass on their All-in-One model, the user noticed horizontal lines sporadically appearing on their screen. To troubleshoot, they took a screenshot during an episode of the lines being visible, only to find that the screenshot came out clear when the lines weren’t displayed. This led them to conclude that the problem was likely hardware-related, rather than due to Software or driver issues.

Checking Hardware Connections

With the display recently reassembled, they diligently checked all hardware connections, ensuring that everything was properly secured. Despite these efforts, the issue persisted. The user reached out for advice on other potential hardware checks they could perform to identify the root cause.

Additional Observations

Aside from the horizontal lines, there were minor concerns about the LCD itself. The user noticed a small black area at the top right corner of the screen, along with a few discolored pixels on the top left. While these imperfections were not significant enough to warrant immediate action, they felt it was important to mention them during discussions about the screen’s performance.

Important Notes

The problem began shortly after the reassembly, remaining absent for the first hour of use but quickly returning. Notably, the lines also appeared during the boot-up BIOS screen, suggesting that the issue could indeed stem from within the hardware components rather than Software.

Seeking Guidance

If you have any insight or troubleshooting tips for diagnosing similar screen issues on an Acer Aspire All-in-One, your input could be invaluable. Whether it’s specific hardware components to check or common fixes, the community’s shared knowledge can help fellow users navigate these frustrating scenarios.

In conclusion, addressing intermittent screen issues like horizontal lines can be tricky, especially after hardware modifications. By systematically checking all hardware connections and considering additional display anomalies, you can get closer to resolving the problem.
