We TV technicians don't go into alignment unless absolutley needed. I would stray away from alignments period unless you understand all of the ramifications that come with them.

SOURCE: how to change lamp in mitsubishi wd 73733

Your TV is so-called V-36 chassis.
First shut off TV and unplug it from the wall.
On the back of the TV on the right hand side if look from behind you can locate plastic lamp cover that is removable. Behind the cover you will see lamp cartridge that held in place by screws that you have to loose using screwdriver. Remove lamp assembly and install the new one. Make sure that cartridge is all way in, you have to feel connection plug to be slide-in all the way. Tighten up screws but not too hard.
Reinstall lamp cover. Plug TV into the wall and wait for green LED light to stop blinking. Turn TV set on. It should display message "Power loss, did you replace the lamp?" You hit "enter" on your original Mitsubishi (not the cable box or Satellite box) remote control and this is it.

I hope this helps please rate that it helped you so i know it did. thanks

1. Turn off your monitor.
2. Get yourself a damp cloth, so that you won't scratch the screen.
3. Apply pressure to the area where the stuck pixel is. Try not to put pressure anywhere else, as this may trigger the creation of more stuck pixels.
4. While applying pressure, turn on your computer and screen.
5. Remove pressure and the stuck pixel should be gone.

This works because in a stuck pixel liquid in a subpixel has not spread equally. In combination with the backlight of your screen, this liquid is used to allow different amounts of light to pass through, which creates the different colors.
Should all of these approaches fail to fix your pixel warrior, at least you'll now know it's not simple to fix and the LCD may indeed need to be replaced. But please do let us know if these tips helped you to fix your pixels. In any case, good luck!
