Question about LG 32LC7D Television

Connecting PC to TV

A while ago my computer screen died out and for a while now I have been connecting my dell xps with Vista to my LG 32LC7D Television with an RGB-PC cable. I did nothing to set this up, it simply worked the first time I tried it.
The quality has been excellent and what would happen was on the RGB-PC channel on the tv it would say "no signal" when my computer was shut off or if I had been inactive on the computer for a while. However when I turned it on (or if I just moved the mouse when I was inactive) it would say "invalid format" for a second then the image would pop up anyway, no problem.
for the past week however the image had sometimes become staticy or start to move around for a few minutes and sometimes the signal would go dead and after a few minutes of turning off the tv or unplugging and replugging in the rgb cable to the tv it would fix itself.
3 days ago though I lost the signal again and now it appears to have become permanent. I bought an S-video cable which is what I'm using to type this now, but compared to my rgb-cable the quality is not only horrible, but its really getting to my eyes.

What do you think the problem might be, and how can I fix this?

    Just an update. I know now how to fix the problem, but I don't know how to stop the problem from happening.

    How I fixed it was to go on my computer with the s-video cable and right click my desktop to personalize. I then clicked display settings while my s-video cable and rgb cable were plugged in even though the rgb cable wasn't showing a picture it did show as the second screen for my display settings.
    I think it was either when I "extended my desktop" to the second screen (the one connected to my rgb pc cable) or when I kept changing around the resolution on my second screen (and checking what happened) that I could finally see my desktop on my rgb connected screen. Then I just clicked in Vista to make my second screen "my main monitor" and when I went back to my rgb screen it worked.

    A few days later the problem happened again, and I had to shut down the computer manually unplug the rgb cable and turn it back on so it only detected the s-video cable and made that one my main monitor again so I could sign in.

    When I play around with the "display settings" like I did last time it will evantually turn back on my rgb screen (a little dim at first, but it fixes itself after an hour or so) so I know the solution.

    I just need to know how to stop it from happening altogether now.

Sorry guys sound is not ment to be transmited through a rgb cable its just for higher quality video you can use a the red and white RCA inputs to get sound to your tv but you need a headphone jack -rca cable or if you tv has a headphone jack just buy a cable with one headphone jack on both ends
hope this helps

All other input works fine e.g. dvd, TV went pink screen.

If other inputs show no problems and you are not using a cable box or satellite receiver, etc. just off air antenna, something on the main board is failing. please double check other inputs again.

32" 32lc7d after a few minutes, flickers, then goes dark.

There are no fans in this model but it looks like either the backlights in the screen are breaking down after they have warmed up or a problem in the inverter board, again part of the driver circuit breaking down after a period of time. They inverter boards can sometimes be replaced seperatly but usually come with a new screen which if the backlights are at fault then the screen would need to be replaced.

LG 32lc7d lcd tv the work find for about 5min. Then the on screen menu comes on the screen then it gos off the remote will not work what board is it ?

Maybe the remote has some keys that are stuck together on the membrane pad. Take the batteries out of the remote, then turn the TV on again see if the menu problem is still happening. Also check the menu button on the TV see if it is stuck by pressing it a few times.......

If all seems ok but still have the same problem, then the the keypad board in the TV needs to be checked for intermittent shorts or opens. If the keypad board is good then the main board needs troubleshooting. This seems like an EEPROM problem, you may want to test that first on the main board.

any questions please ask....

Connecting to PC

Hi Sarah, You may want to try lowering the resolution of your computer down first before connecting the 42PX5D. Since everything seems to be working except when you get to the desktop then your PC might be set to a resultion that's too high for the LG (am not 100% sure, but I think that LG's max res is 1024 X 768). Try to adjust your PC's resolution while still connected to a regular monitor, right click on any free/clear part of your desktop and click properties. Display Properties window will pop-up, click on Settings tab, adjust Screen resolution towards the left,trym lowest posiible, color quality, again lowest possible. Then hook it up to the LG. If desktop now displays in LG, do the same again but this time going up. Do it by increment and stop when LG screen goes blank. Press escape to go to setting prior to blank. Adjust color quality best setting acceptable to the LG. Good luck and hopes this work out for you. Regards.
