Re: Mitsubishi 57833-I Think I Messed UP
So after all this trouble shooting basically you end up with a RED screen??? If you are getting an image then the light is working (that only emits white light), I think maybe the coorwheel is not spinning or something was not plugged in correctly.. normally when i rebuild a big screen TV like this, sometimes I get a band top or bottom! And I loosen the entire light engine and move it around, if you no longer get the black band maybe either the colorwheel is/went bad/damaged or the light tunnel is severely miss aligned. You can rectify this by taking everything out and rebuilding it piece by piece, connector by connector and making sure every screw and plug are snug..
Good luck and keep us posted!

Ok so by what you describe I am almost certain this is ballast issue. This is completely normal, chances are if you Google it you can find a guide to replace it.
This is a consumable part so even if it was not defective once the lamp has been replaced on a Mitsubishi DLP 2-3 times the ballast needs to be replaced..
Hope this helps!

Re: Mitsubishi 57833-I Think I Messed UP
Quick question. Is there any way to test a lamp outside of the set? A meter or anything to check if a lamp is good or bad? The tv is probably past putting more money into but I'd like to know that both lamps I have are good, in case I decide to sell them. Thanks for any help.

I do not think there is a way to test the lamp outside the TV without a proper safe bench workstation and the corresponding ballast. Keep in mind the ignition jolt is 5-20kV!
Taking a multimeter, as proposed, will render a false result because of the arch gap in the uhp chamber..
