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 Most of them are sold with drivers that are outdated.

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.

SOURCE: Connection with VGA cable to pc says "invalid

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.

I have a bunker hill item 62463 dvr security system and all i get on my T.V is invalid Format it will do nothing else

You need to use the TV remote, and change the input to video, or DVR ...or something. Run through the various input channels, and you will find it. Invalid format is like if my TV is set to RGB/PC input, but the screen has timed out and is in sleep mode (no display) puts invalid format on the screen. Or if you go to straight TV instead the channel that's connected to the box, same thing. You have to have the right input selected. You usually need the remote for it.

"Invalid Format" message


This should help you. I think Chris Duckworth said it best. "sounds to me like your refresh rates or resolution may be set too high on the XP machine."

Go to this website to get the rest about setting up your tv as a monitor. Type invalid in the word search to get to the relevant section.
