Lg 42PX4dv PC connection

Hi, I just connected my PC to the Plasma with a 10M cable 15pin VGA D15 made by concord. Part no WQ7258 when I boot the Pc the signal is picked by the plasma and the screen appears on the RG input screen. After about 30 seconds or so the signal is lost then it comes back on for a few seconds showing the window bar as the PC boots up then the signal is lost again and the plasma displays NO SIGNAL ON THE SCREEN. Is there anything I can do to keep the signal displayed? The cable is brand new. Regards DarrellB

    I have LG 50PC55 50 inch plasma, and when I conect it via 15pin D-sub cable to my computer, the TV can not find any signal. Computer recognizes TV's chipset, screen resolutions and refresh rates, but TV does not find any signal from computer. If I conect the same computer with the same setings to eg. Sony or Philips LCD or plasma TV, it immediately gets the signal and shows picture. Is there any seting in TV's service menu where I can activate VGA input?

I think the problem is the screen resolution and size of your pc is not matching the resolution size of your tv or is not compatable at the size you have it on or you may have to change to 4:3 ratio from widescreen. In your manual it will tell you the resolution sizes that you tv uses. You would probably be better also using the VGA to DVI lead, thats if it came with the tv (it does in the UK) as it supports higher wide screen resolution, whereas VGA will only support 1024 x 768 or there abouts.

I'm trying to connect my Dell xps pc M1530 to my samsung lg tv. I have a 15pin vga cord connected. Still not working. Can you walk me through these steps?


After connecting the VGA cord, try the following:

  1. 1. On our laptop, go to display settings (right-click on desktop > properties) to see if you have the ability to switch to different monitors.
  2. On your TV, check if you have to switch through connection type (HDMI, VGA, etc...)
Hope this helps.

Lead from external harddrive to tv- to show films,--usb connection from harddrive to 15pin to tv

Dear ragalgey,
As far As I can remember, most TV design to receive the signal to watch whatever you want limited to available TV station in your local broadcaster.
If you think you connect your harddrive to TV USB or 15pin (VGA cable) then you can watch the movie file from harddrive is a totally wrong!
You need a drive or a player for those file that capable to configure your TV to play them. Or at least you need a PC or Laptop Computer that played your harddrive then send the images/video via Video Out Jack (Yellow) from your laptop, or connect the 15pin VGA jack from Laptop PC out then plug in to your TV. In this case you'll need the Jack/adapter to convert from 15pin VGA from laptop to available Video jack on your TV.
Good Luck!

Best Regards,

How to connect samsung pasma tv to pc?model number is PS42B450B1XUM


That does depend on the PC, but I'll assume it's a pretty standard PC.

You ideally need a Male 15Pin VGA cable to Male 15Pin VGA cable. (aka A normal Monitor Cable) The same as you probably have connected between your PC and Monitor.

Your TV has a 15Pin VGA Female socket on the back, this cable plugs into here.

For Sound the TV has what looks like a headphone socket next to the VGA Plug. You need to use a Stereo Jack Plug to Stereo Jack Plug Cable. 3.5mm. This goes from your PC's Audio Line Out (rear of the PC) to the Plug on the rear of the TV. It is usually marked Aux In or PC Sound.

Enjoy, The PC will look great on the Tv.

Samsung LCD TV not receiving PC signal

Check your vga cable. Some cables have only 14 pins, some have all 15. The missing pin is pin 9, in the 15 pin cable it carries 5v from the graphics card to the screen. Without that 5v signal most LCD and Plasma television screens won't recognise a PC input. I had the same problem and only managed to fix it when my girlfriend swapped a cable over for me and as she did so glanced inside and said "it's got a bit missing" The cable that came with your PC most likely only has 14 ins as that is all a monitor screen needs.
You can buy a 15 pin cable at most PC or electronic shops, just check that isdoes have all 15 pins befiore you buy it. The cheap ones are just as good as the expensive ones unless you are buying 20 foot cable. For 6 foot cable the cheap ones are just as good as the expensive ones.

I have an LG 42" 42PX4DV Plasma, keeps resetting itself.

Do you use a regular antenna, or cable/satelits tuner?

I use only satelite tuner, and had the same problem on a differnt TV. I solved it by connecting a regular antenna (actually just a piece of cable) and go through the search and store routine once. Then the TV remembered that it was configured. Before that it thought it was "fresh out of the box" every time.

LG 42PX4DV - HDMI Audio / PC Audio IN problem

I found the fix. Had the same problem.
I right clicked on the sound speaker icon in the bottom right of Windows 7.
Chose Playback Devices.
Once this window opens, then make sure you are on the Playback tab.
Scroll down until you see the HDMI Device. (Mine was hidden at the bottom of the list.)
Then choose "set as default".
The sound will begin playing on the TV with only the HDMI need for an extra audio cable.
