Video split in four parts

[Renato53]

My pavillion 9000 has the display horizontally divided in 4 parts, even at boot time, entering BIOS setup.

Sometimes, at a new startup, all is ok, but then it switch again in the fail mode and no work is possible

@Renato53, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding Display Issues on HP Pavilion 9000! 

We're thrilled to have the opportunity to assist you and provide a solution.  

The issue with your HP Pavilion 9000's display being split into four parts could be due to a few potential causes such as a failed display, faulty graphics card, or loose connections. Here's a step-by-step guide to troubleshoot and potentially resolve this issue:

Quick Check:

• Verify that the system is getting power and that system light activity appears normal.
• Remove all external devices like a docking station, as recently added hardware can cause conflicts, especially during boot.

Perform a Hardware Reset:

• Turn off your computer completely.
• Disconnect any connected devices and remove the power cable.
• Press and hold the power button for about 15 seconds to drain any residual power.
• Reconnect the power and peripherals, then turn the computer back on.

External Display Test:

• Connect your laptop to an external monitor through the VGA or HDMI port.
• If the external monitor displays correctly, the issue might be with the internal display or its connections.

Verify Display Connections:

• If you are comfortable doing so, check the physical connections for the display within the laptop. Reseat display cable connections both at the system board and display panel side.
• Ensure there are no visible damages to the cables or connectors.

BIOS and Driver Updates:

• If you can boot into Windows, ensure that your BIOS and display drivers are up to date. Use HP Support Assistant to check for updates, or visit the HP website to download and install the latest versions.  

Hope this helps! 

Take care, and have an amazing day!
