HDMI output to TV stopped working on HP Pavilion G6

[protagonyst]

I have been using my laptop on my Sony Bravia TV using the HDMI ports for over two years without problem. I unplug it and plug it back in on a regular basis without problem. I returned home after a weekend out of town and plugged my laptop back in and kept getting the following error message on the TV:

No signal. Check the external input or select another input using the INPUT button.

 
TV:

Sony Bravia KDL-40BX420

Laptop:

HP Pavilion G6 with Intel HD Graphics 3000 graphic adapter with latest drivers (Intel HD Graphics Driver for Windows 7/8/8.1 64-bit, v15.28.20.64.3347), Windows 8.1 64bit

What I tried:

• Tried with 3 different HDMI cables (unsuccessful)
• Tried connecting DVD player to TV's HDMI ports (successful, plug and play)
• Tried connecting PC to a different TV using HDMI cable listed above (successful, plug and play)
• Tried resetting TV to factory settings (reset successful, still no signal from PC)
• Tried power reset on the TV (unplugged for couple of minutes, plugged again, still no signal from PC)
• Tried reinstalling PC's graphic drivers (Intel HD Graphics Driver for Windows 7/8/8.1 64-bit, v15.28.20.64.3347, from Intel's website, install successful, still no signal from PC)
• Tried installing latest graphic drivers from manufacturer's website (Intel High Definition (HD) Graphics Driver, v9.17.10.2843, from HP's website, install successful, still no signal from PC)
• Tried different video resolutions on the PC, duplicate output...
• Tried different startup sequence, with mixed results:
• Turn on PC than turn on TV: no signal.
• Turn on TV than turn on PC: I see the Windows 8's logo with the white rotating dots on the TV (duplicate from the PC screen, and before getting to Windows' login screen, the TV's turns turquoise with the "no signal" error. So HDMI does work, but only for a short period of time during Windows bootup sequence.
• Tried System Restore to a restore point from a week ago (HDMI to TV worked well all week), no luck. Still no signal to TV, and the PC keyboard stopped working too. Undid that.

I'm out of options. Help would be much appreciated. Please just keep in mind that it has been working for over two years without any special setup. Just plug and play, as it's supposed to.

Thanks in advance

Hi protagonyst,

Welcome to the HP Forums!

I would like to take a moment and thank you for using the forum, it is a great place to find answers. For you to have the best experience in the HP forum, I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.

I see you have been connecting your TV via HDMI to the notebook for the last two years. You have always been able to disconnect and reconnect the TV without issue, but today you get the message no input.  You have already completed the troubleshooting steps to no avail.  When you turned on the TV and then the PC and you had the Windows logo come up, it is receiving a signal, but looses it once the driver is installed. Here are the two suggestions I have. You can try reinstalling the original driver using the HP Recovery Manager.  Using Recovery Manager to Restore Software and Drivers (Windows 😎. If that is not successful, I would do a full recovery.  Performing an HP System Recovery (Windows 8).

If you would like additional help. please provide your exact model of HP G6 you have. How Do I Find My Model Number or Product Number?

Thank you for your reply. You summerized the situation pretty acurately. I will try your suggestions when I get back home tonight.

Here are my laptop's exact model:

Product name: HP Pavilion g6 Notebook PC

Product number: A7G84UA#ABC

Best regards,

All my attempts at using HP Recovery Manager to restore the graphic drivers led to the same result: an exclamation mark next to "Intel High Definition (HD) Graphics Driver version 8.15.10.2476", followed by the this error message:

One or more of the selected driver(s) and/or application(s) may not have properly installed and have been marked with "Exclamation mark". Please unistall these from the computer before attempting to install them again from HP Recovery Manager. (error code=5)

I uninstalled the driver from Control Panel > Programs and Features, restarted PC. Then HP Recovery Manager > Drivers and Application Reinstall, select "Intel High Definition (HD) Graphics Driver version 8.15.10.2476", install, error.

At this point, the driver no longer appears under Programs and Features.

I uninstalled the driver from Control Panel > Device Manager > Display adapter > "Intel(R) HD Graphics 3000" > Properties > Drivers > Uninstall, checked "Delete driver software for this device", OK, restarted PC. Then HP Recovery Manager > Drivers and Application Reinstall, select "Intel(R) High Definition (HD) Graphics Driver version 8.15.10.2476", install, error.

And after a little while, "Intel(R) HD Graphics 3000 v9.17.10.3347" is reinstalled automatically (appears in Device Manager), even though I checked "Delete driver software for this device" earlier.

It seems I'm unable to get rid of v9.17.10.3347 and rollback to v8.15.10.2476. And still no signal when I connect the laptop to my TV through HDMI. Any advice before I go full recovery?

HI protagonyst,

I see that you attempted to install the previous driver but were not successful.

You can choose the driver to install, if you know where it is located.

Open device manager

Uninstall the current driver

Right click on and choose update driver software

Choose Browse my computer for updated driver software and direct it to the desired driver to be installed.

When you restart, I am not sure if the HP Support Assistant will try to install the updated driver or not. If it does then you will need to reinstall the desired driver and then set the HP Support Assistant to manually do updates and not automatically. This will allow you to choose if you want that update or not.  Good Luck!  Hopefully you will not need to do the full recovery.
