Question about Mitsubishi WD-73733 73" HDTV

Open Question

My Mitsubishi WD-73733 won't turn on. It started with a noise as it started up, coming higher on pitch and then lowering it, and doing this three times. Red light will turn on. So I purchased a new lamp. Installed it (got audio to begin with), but the same thing happened. I'm getting an error code 66 with both the old and new lamp. Any ideas?

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: Mitsubishi WD-52525 52-inch DLP HDTV ywllow warning lamp light

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours

What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away

or just simple replace the lamp. 915P020010

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.
Regards.
Russ.

My mitsubishi wd 73733 just made a popping sound and went off.when i tried to turn it back on its making noises with no picture goes from a green light to blinking red on lamp inicator do i need a bulb or...


You can actually go with just buying a bulb. I have seen many cases where televisions stopped displaying a picture due to a worn out bulb. The noise is also from the weak bulb.

Want does yellow light mean


If I'm not mistaking I believe Mitsubishi shows the yellow light to indicate new bulbs needed and or overheating. Most common is overheat, but may actually be a bulb replacement required.

TV will not power on, strange arcing and poping noise from rear


Even though the Lamp looks good it does not mean that it is. The only way to know is to relace it. If you have already replaced it with a Mitsubishi Lamp Assy. then the Ballast board would probably be the cause.
Hope this helps,
