Screen color I didn't realize my monitor was only half plugged in (power plug) and when I plugged it in all the way the color went funky: the background is pink and the start button is black along with other things like the windows logo. Have I ruined my monitor?

attach a monitor to the VGA port in the laptop and take out your display to other monitor...

check this thing and revert back to me

Hello WHAT THE HECK HAPPENED !

When power is disconnected from the vehicles on board computers, they reset themselves to factory standards.

To have all system monitors reset themselves... a standard driving procedure has to be followed. Please see the link for a Accent model to give you an idea of what to do. If you can't find the exact procedure for your vehicle, the link for the Accent model should work for your Elantra.

PS: Check to make sure the spark plugs leads went to the correct cylinder.
Are you showing any Service Engine idicators on the dash?

You didn't say whether the plug came out of the monitor or the PC!

If the monitor, look under the back side of the stand, and see if you can find a jack.

If the PC, look at the back of the computer, and locate a similarly colored jack, usually low down on a tower case, and plug it into the same colored jack.

Cheers!

Shut off the tv, unplug it, hold the power button on the tv for 90 seconds. Plug it back in. Hit menu? Do you see a menu? (if not, your tv needs serviced)

You might also have a cracked LCD.

Hello there.
Hope this link will help ya Are Your Screen Colors Distorted or Off Here What to Do
Otherwise you can try an old trick and disconnect all the data cables from your monitor side(HDMI, DisplayPort, VGA, USB etc.) or computer side if the ones on display are built-in. Leave only the power cable. Unplug the monitor`s power cable. Press the POWER button on the front of the display and keep it pressed for 45 secs. Plug everything back and give it a try.
Good luck.

it's just a power cable, no transformer. but it has a funky plug on the end of it

Do this to check if your monitor is in working state or not...!

Step 1:- Turn on your computer.
Step 2:- Unplug the Video Cable of your monitor which is connected with the computer.

( Video cable:- Cable going from the back of your monitor to the back of your tower. It has a plug with two screws on the plug ends, which you can unscrew to unplug it. Thats how it looks like. Some times it is in grey in color some times in blue.)

Step 3:- Now check on your monitor. If the display says " No Input Signal " :- your monitor is fine. Some thing wrong with the computer graphics.
If there is not display and the monitor light is blinking or solid the monitor has gone bad.

( Note :- Remember when you unplug the video cable do not unplug the power cable of the monitor. )

Let me know if it helps.

If the power light dims or changes color after the no signal message comes up, that means the monitor went to sleep.
While the monitor is plugged in and on and the computer is also on, Try unplugging the VGA cable from the monitor. wait 30 seconds and then plug it back in o see if the power button light comes back to normal color and the screen flashes on.
If not, then the monitor is not getting a signal from the computer.
If using a desktop computer,Try a different cord or try the monitor on another computer.
If using a laptop, you need to activate the laptop to use an external monitor. That can be done through the display settings, OR, most laptops have a shortcut key feature which usually involves pushing the Fn key and one of the F keys at the same time. The F key may say CRT/lcd or have a picture of a monitor and a screen.
If the power light does light back up and still no picture, There may be an internal issue on the monitor

you are in a bad spot, the plug is sealed when molded. maybe ebay has a defective monitor and you could take the cable off it.

Monitors will usually snap apart with a butter knife.

I suspect Best Buy will most likely replace the monitor's entire power circuit. It's possible that you shorted out a fuse, the input transformer, or some other component in the monitor's power supply. The only way to tell for sure is to disassemble the monitor and check the circuitry visually and with a meter. This job is best left to a qualified technician.
