It is a common problem I deal with constantly, the main power board was overloaded there is most likely damage to the capacitors or a transformer on this board. you will need some service tech to take a look for you so he can identify the issue. hope this clear up what you need to do

I HAVE LOST SOUND DRIVER OF RTL8101L WINDOW XP..


Get onlineand got to www.google.com In the google search box type: "LGSupport" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operatingsystem when requested. Download and install the Audio drivers.
You can also try the VLC Player, it comes with drivers and codec.
Try using VLC as your player. Go to www.google.com andin the search box type "download vlc" (without the quotes). Look for the Video Lan download from site www.videolan.org/vlc Downloadand install it. It downloads and installs in 3 minutes or so. It'sa very fast player, smooth and it can play just about any type of dvd formatsand media. It's totally FREE.

Hello have a problem with tv Model is: lg


http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=6281

The above link goes to lg's website describing the red flashing light where the power switch is, and

another switch down below which can turn that light off.

Try switching that other switch below off so the light turns off. Then, switch it back on.

If that doesn't work, then service should be scheduled for this discontinued model.

Hope this helps on your lg tv.

Computer dead and beeping


If it beeps and not boot then it is the post routine telling you there is a problem. The post routine is run when you turn the power on to ensure the computer hardware is ok to run. The manufacturer of the bios routine can tell what is wrong by the type, number and duration of the beeps. Look up the code meanings and it will indicate the problem. If this sounds like nonsense to you then give the make and model of your machine and what the beeps sound like. ( beep beep beep delay beep beep beep) etc. and I'll look it up for you.

I have an acer 5335 aspire laptop and tried to connect it to a 127cm lg plasma via vga cable. I changed the resolution on the laptop and tried using Fn F5 key however no result.


Does ur video card support tv out?
If it does, u cannot use ur screen AND a tv at the same time.It's one or the other. Go to the display options and select the tv out option for ur vid card. Ur screen will go black and the tv will then have ur desktop.

Sony plasma tv was working fine, now there is a large black strip going from the top of the screen to the bottom, about six inches long, where it only displays a black strip.


Post your problem in the right category with your model listed if the category doesn't already exist, so you can get relevant feedback.  As it is, clearly your TV got its connection along that column interrupted; carefully seek to clean and dry whatever fluid fell down the screen into the interface....

Every time i turn my lg plasma tv on the on light just flash's but the tv won't turn on


Hi Willydogg,

To my knowledge, if this occurs in a plasma TV, then it might be an issue with the board located at the base of the TV (where it governs color distributions and stuff like that). You might wanna call down the LG techie to come and change the board for you. Hope this helped.
