HP pavilion dv6000 speakers wont work


If you've check the Audio and Sound properties in the Device Manager then maybe the speakers are shot. Click Start/Control Panel and look for Sound or Audio and check the properties and settings. You can also click the Megaphone at the bottom right near the time. Make sure the Volume is turned up and not on Mute.

You can look on ebay and purchase replacement speakers based on a HP DV6000 Speakers search. You'll have to take the laptop apart to install them.

You could try downloading and reinstalling the Audio Drivers.

Get online and got to www.google.com In the google search box type: "HP Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operating system when requested. Download and install the Audio drivers.



Try using the VLC Player. It comes with drivers and codec. I've seen it solve many sound issues.




Try using VLC as your player. Go to www.google.com and in the search box type "download vlc" (without the quotes). Look for the Video Lan download from site www.videolan.org/vlc Download and install it. It downloads and installs in 3 minutes or so. It's a very fast player, smooth and it can play just about any type of dvd formats and media. It's totally FREE.

Back Light Failure???


I had the same problem. Based on other resutls of a Google search, I replaced the backlight inverter board. That fixed the problem. I got my substitute board from http://www.lcdparts.net/LCDTVInverterdetail.aspx?InverterOriginal=V144-001MSS.

All you need to replace the board is ap hilipps head screw driver and be comfortable taking electronics apart and handling PC boards (you need to take a couple of layers off before you get to the board).

HP LC3040N I have sound but no image


In my case, the backlight flashed on for less than a second, then went out. Turns out the backlight inverter was bad. I replaced it (got mine at http://www.lcdparts.net/LCDTVInverterdetail.aspx?InverterOriginal=V144-001MSS) and everything works fine.
