HDMI port not working on Pavilion DV7

[OldPavdv7]

Cant find the HDMI port/controler in the hardware configuration list anymore (hardw. divices =>controlers for sound video and games).

When connected (tried two different cables) to ext. Samsung TV's HDMI ports, no sign of live. All soft is up to date according to "HP support assistant". Anyone an idea what to do? Bios is  latest version f.29.

HI @OldPavdv7,

Thanks for taking an interest in the HP Support Forums!  It is a great site to get support, resolutions and answers from experts in the community. I understand that the HDMI port does not work after an update. I’ll really be glad to assist you with this.

I would require some information about this to assist you better.

1. What update was done on the machine? Was it a windows update or a software update?
2. Have you tried a different HDMI cable to check if the display works?

 Please try these steps to isolate the issue to really being hardware related.Please perform a hard reset first. Steps to do it:

• Power down the computer and unplug the charger. Then remove the battery only if it is a removable one.
• Hold down the power button of the unit for 15 seconds to discharge static electrical charges inside the machine.
• Replace the battery and reconnect the charger.

• Then the instant you power on the unit, keep tapping the “ESC” key gently several times.
• It takes you to the startup menu. Here please press the F10 key to go to the bios.
• Please check by connecting the computer now to the TV, using an HDMI cable.
• If it shows a display then we can clearly deduce that the issue is a software one.
• Please don’t forget to check with another HDMI cable also.

Once it is clearly established that the HDMI port is not faulty, Please perform a system restore to a good known working date to correct the situation. Please visit this link to perform a system restore: http://support.hp.com/in-en/document/c03327545

Please follow the step “Restore your computer when Windows starts normally” to complete the system restore.

Let me know if those steps worked for you.

If they did, that’s awesome!

Good Luck.

Genlty (rapidly & sequently) pressing the escape button doesn't bring me anywhere except normal Window startup screen...

In the mean time, I just recently had a big upgrade from MS, bringing the latest W10 vers (took hours).
I now see a second driver in the audio, video & games device list, but no change in the HDMI, it still doesn't work.

Should I install  vista drivers?

And yes I tried do different cables...
