Check your cables between the receiver and your TV to make sure the colors match. If you are using a component cable (green, blue, red, white, red), not matching colors at both ends will give you what appears to be a black and white picture. I hope this helps.
Yes,the problem is the colors wheel it dead.That one of the cause by the colors wheel,other are alots of squiling noises and making very loud buzzing sound.The cooling fan that u think is overheating,does it stop sometimes,when the tv is still on?Yes,than replaced it also,no than it still ok.Just hire the tv repairman,the parts he'll take care of it,don't order the parts,u might get the wrong parts or different sizes,that will not fit in ur tv.
Hi,it definetely sounds like the color wheel.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.Found your color wheel here: http://www.discount-merchant.com/MITSUBISHI-00-L3603-002-p/1162430.htm Have a bless one!
Can you post to the party who has too much green how to adjust the video adjustments? They need to know so they can see if
its just a simple adjustment.
In your case, first turn the color level clear down to where you
have a black and white picture. As in the case of too much green,
question is if the picture is black and white or if there is a color
on the screen so its blue and white? I suspect it will be which
is typical when the guns start to fail. Likely the green and red
guns are weak in output. There are screen adjustments in the set that a tech can set up that may help some, but the only real fix is to replace the guns which is expensive and requires a complete allignment. All 3 guns need changing to get it back to spec and it is a good idea to replace the flyback for reliability. Get an estimate and likely you can replace the set for the same money.
Turn the color level all the way down and see if you have a good black and white picture. If your screen isnt black and white it should have a predominate tint to it. then turn the screen control for that color down to achieve the best black and white picture. then adjust your color level that should help.
