Monitor outputs from PCs can be very fustrating. First of all, is the PC a laptop? If so most of them do not have a dual monitor capability for supporting an external monitor, or if they do it can be difficult to get it to use both monitors at the same time. Try updating the drivers for the video board. Most of them are sold with drivers that are outdated.

SOURCE: invalid mode is on a blue VGA input screen with

It is becuase your PC video resoliton is too high for this TV to display, max resolution for the PLTV3250 is 1366 x 768 @ 60 Hz.
Also watch out for this TV power supply to go out due to bad caps and it will take out the transistor and Diode with it.

You PC video card resolution is too high for it to display, you need to set your PC video resolution to the native resolution of this TV.
1366 x 768 @ 60 Hz

If your TV goes out and it will, please read below:
Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out Q7 and ZD4.

You get 'INVALID FORMAT' because the video signal source resolution is too high for the TV to display, you need to lower your video source resolution.

Invalid format message when trying to use the RGB(PC) port


Honestly, that sounds like one of two things happened. Either the resolution of your computer video card changed or (I'm not sure with your specific TV) the TV's resolution changed.
If through the TV menus you can adjust PC resolution, I would try changing the resolutions. In the LG 47LB5DF TV, press Menu, then go to Picture, then go down to Screen. On the screen menu, you will see Resolution, Position, Size, Phase, and Reset. First try adjusting the Resolution to some of the options you see. If that doesn't work, try to reset the screen settings.
If adjusting those settings on your TV does not help, then you will have to change the resolution through the computer. Try connecting a monitor to the computer. If you get a picture through the monitor, on the desktop right click and select Properties. If using XP go to the setting tab, if using Vista/7, select Display Settings. Lower the resolution to something you think the TV will be able to handle, then connect the PC to the TV again. If you are using an HDMI connection to the TV, you may have to turn off the computer, connect the cable, then turn the computer back on with the TV on the correct input.
If the monitor doesn't show the picture or if you don't have another monitor, you can try adjusting the picture in safe mode, by pressing F8 after you press the power button, before you see the Windows loading screen. Press if multiple times if necessary. You should see a screen that gives you a few startup options. Select Safe Mode. After Windows boots up, you should still see the screen as the resolution would have been reduced. From there try changing your display settings.
Hopefully that info has helped. I noticed that you asked this question 2yrs ago, so I hope you have already figured out how to fix your problem. I simply wished to post this in case it would help you or anyone else had a similar problem. Good luck and take care.
