Question about LG 42LC2D 42 in. LCD HDTV

Open Question

No audio from Dell laptop to some LG TVs

Hi, I have just purchased a Dell Inspiron 1525 laptop loaded with Vista Premium. The main purpose is to play my media files to TV. I have 3 TVs all LG. When I plug the HDMI cable V1.3 from laptop to the TVs LG 42LC2D-AA and 47LY3DE-AA, shows the picture but no audio. On the laptop under Sounds, Playback Devices, it either don't show HDMI device or says it is not plugged in.

The other TV, LG 50PX4RA-TA is able to detect the HDMI and shows under laptop Sounds Device Playback when I connect and plays picture and audio fine on TV. It automatically switches back to laptop speakers when cable is pulled out. That's should be the way it works.

BTW, I have a Western Digital Media Player and plugging to hdmi works fine for all 3 TVs.

So I am thinking there is not a problem with laptop vista and hdmi driver, cable is working. So what is wrong with the hdmi ports on those 2 LGs TV? I tried to play with TV audio settings but no luck. So can someone please give me a solution.

Thanks, Phil

SOURCE: LG 37LG30 HDMI no sound problem

This is more probably a software fault within the TV. They need instructions for HDMI inputs & a no sound is a related fault. I would get in touch with your dealer to arrange the TV to be updated to cure this problem. Hope this helps.

SOURCE: When i try to play a Blue Ray DVD, the LG LCD tv

Pickled! You did right by checking the cables, the tv inputs and as well the output on the blue ray...even by replacing the blue ray. Which leads to a problem within the tv monitor. I can only guess there is something in the software of the tv that is causing the problem. I can only suggest two options. If can connect the tv to a network via CAT5 cable, you can do a frimware update to the tv. Sort of like a software update. If it is not available, try to swap the HDMI cable for the 5 RCA component video. It will still carry HD signal, just not as crisp as the HDMI. I would be floored if the same thing happened with the component cable.

SOURCE: Sony Bravia does not recognize my Dell Inspiron 1525

I have the 1525 and you have to do extra steps each time you want the HDMI to be recognized by the Bravia - too bad it is not automatic as it is with some. Anyway what you have to do is have the HDMI cable connected from laptop to TV then go to your desktop - right click on an open area (away from icons), a menu will appear, let the cursor hover over Graphics Options - you'll then see Output To...then you'll see Intel Dual Display Clone...hover over that and you'll then see Notebook + Digital Television...left click on that and you should see your desktop on the TV in a few seconds. If it does not work the first time...get your movie or whatever you want to show up and ready and go thru these steps again...stupidly complicated aye? when it should automatically detect and show...are other TVs like this?

I have an inperion 1525 and after i reinstalled windows vista home premium, the internal speakers stopped working


It sounds like a driver issue. Go to http://support.dell.com/support/downloads/index.aspx?c=us&cs=19&l=en&s=dhs and enter your service tag. It should give you a list of available drivers for your system. Make sure that it specifies Windows Vista in the drop down menu. Check for audio drivers and install the most recent one.

Dell Inspiron 1525 buzzing sound


As you mentioned that you have downgraded to windows xp, did you change the sata operations to ATA mode from AHCI mode in bios before installing XP? If you have done this then try and reinstall webcam driver and also the audio driver. If possible get into device manager to check if all drivers are working fine.

SInce SharePoint Services 3.0 and SharePoint Server 2007 does require a server interface to run the collaboration tools you are unfortunately stuck with running it on server software. But all is not doom and gloom as there is an option for you to run Microsoft's Virtual PC. Here is an article on how it works from Microsoft.
