Owned for 1 year( I Buy 2 pcs on amazon.com in 8-23-2023). No physical damage whatsoever. Screen blacked out now. 

only show Vertical lines. 

Monitor is detected by multiple devices. open the monitor(no connect any device), only show Vertical lines

 

Power adapter works fine(because i have 2 same U32). 

 

Why would a high quality monitor become defective in only 1 year? How can we solve this issue? How can I repair this monitor. 

 

I spent $409.99/pcs, it shouldn't only used for 1 year

Hi @LEOWGL,

 

Welcome to The HP Support Community.  

 

Thank you for posting your query, I will be glad to help you.

 

I understand you are facing an issue with your HP U32 4K Monitor has developed a hardware fault. The issue with vertical lines appearing even when no device is connected suggests a problem with the monitor's internal components, such as the LCD panel, T-con board, or internal connections.

Troubleshooting Steps

Power Cycle the Monitor:

  • Turn off the monitor and unplug it from power.
  • Hold the power button for 15–30 seconds to discharge any residual power.
  • Plug it back in and test it.

Check Different Cables and Ports:

  • Use a different HDMI or DisplayPort cable.
  • Connect the monitor to another port on your computer or a different device.

Self-Diagnostic Test:

  • Many HP monitors have a built-in diagnostic mode. Unplug any cables connected to the monitor, leaving only the power connected.
  • Check for any instructions in your monitor's user manual about running diagnostics (e.g., holding specific buttons to trigger a self-test).

Firmware Update:

  • If possible, connect the monitor to a working device and check HP's support website to see if a firmware update is available for your monitor model.

Inspect for Physical Damage:

  • Check for any visible damage to the screen or casing.
  • Ensure no loose or damaged cables inside the monitor by carefully inspecting (if you're comfortable and experienced with handling electronics).

I hope this helps. 

 

Take care and have a good day.

It must be that some property inside was not pressed tightly, so I tapped it a few times casually and started working again.
