Power cable or connection to HP M22f FHD IPS Monitor ureliable

[TriciaBooth]

The monitor (M22f 21.5 FHD IPS) that was bought two months ago with a desktop computer from HP is now having problems starting its display. It worked fine up to recently. It is now blinking, or not coming on at all. Investigating, we found that putting some pressure on the power cable connection into the monitor would put things back to normal. So either the cable end or the monitor interior connection is not good. Can anyone suggest a permanent answer? Is this a known problem?

Hi @TriciaBooth,

Welcome to the HP Support Community. 

I'd be glad to help you! 

I'm sorry to hear about the difficulties you're experiencing with your monitor. Let's work together to resolve this issue. To better understand and address the problem, could you help clarify a few details?

• Have you tried using a different power cable to see if the issue persists?
• When the monitor is working, does it display any signs of flickering or other anomalies, or is the display completely stable?
• Is the power connection snug and secure, or does it feel loose when you plug in the cable?

Let's try these steps. 

Inspect the Power Cable:

• Check for visible signs of damage, fraying, or bent connectors on the cable.
• Try connecting the monitor with another compatible power cable to rule out a faulty cable.

Verify the Power Port:

• Carefully inspect the monitor's power port for any debris, bent pins, or looseness. Use a flashlight if necessary to ensure it is clean and undamaged.

Secure the Connection:

• Ensure the cable is fully inserted into the power port. If the connection is loose, try slightly adjusting the angle or using another cable to confirm whether the port itself is the issue.

Test with Another Power Outlet:

• Plug the monitor into a different power outlet to rule out any issues with the current power source.

Contact HP Support (if needed):

• If the problem persists and appears to be due to a faulty power port, reach out to HP Support. Given that the monitor is only two months old, it should still be under warranty, and you may be eligible for a replacement or repair.

If the monitor functions fine with a different cable or after ensuring a secure connection, you can avoid additional steps. However, if the issue seems tied to the power port itself, I recommend you contact phone support. 

Hope this helps! Keep me posted for further assistance

Thanks for your reply. To try to answer your questions, we have no alternative power cable to try, BUT, the cable provided is in good repair with no defects.
We have discovered that pressing the power cable more firmly into the monitor results in the monitor working as normal.
However, this means we are having to leave the monitor switched on to ensure continual use.
The problem appears to be with the connector inside the monitor therefore. When it is working, with the cable pressed firmly inside, there is no flickering or fade out, only when the cable is put in "normally" without added pressure.
The power port is undamaged, by looking on the outside. Obviously we cannot check the inside without taking the back panel off.
I must add that we have now viewed a number of videos online where the fault has been identified as a wobbly power switch on the inside of the monitor.
It does seem therefore to be a fault with the monitor which, as you say, would mean contacting HP for a refund or replacement. (But since this does seem to be a known fault with the monitor I'm not sure a replacement would be acceptable.)

Hi @TrishDerby,

We apologize for the inconvenience. The issue seems to persist even after attempting the troubleshooting steps mentioned above.

This might require one-on-one interaction via remote assistance to fix the issue over the phone.

Thank you. The problem has now become one of a screen fault - blackness over half the screen, flickering etc - so there is definitely a reason to approach HP support. Meanwhile however, we are forced to source an alternative monitor locally, and in consequence my husband is picking up a monitor this afternoon to get him through the current situation. It therefore looks like a refund of our money would be the only HP option. (By the way, the link you kindly provided doesn't work for me. It says "Access Denied. You do not have sufficient privileges for this resource or its parent to perform this action." But it's okay, I will do it elsewhere. I cannot find the button for marking the reply as the Accepted Solution, or else I would click it. Sorry.)
