When I first turn on the Toshiba projection tv the color has a strong red hue to it which clears up gradually

I would suggest when turning set on cold---turn color all the way off and examine screen as set warms up---if red to some degree but gradually becomes black and white the issue is either a "touchy" red screen control on the screen/focus block or a problem on the circuit board plugged to the bottom of the red tube.

I guess the real question is how long until it is normal?

My five year old Toshiba 57H84 rear projection TV has a pink tinted screen when you first turn it on, then after it warms up, the colors are all fine but then the picture has evenly spaced blue tinted...

Hi,Yes your problem sounds like the DMD board.This is how it works: Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : Have a blessed one!

Screen turns red to mutch to fix $$$$

This is a simple fix and not hard to do, first you must get the speaker grill off, usaly two screws on the bottom and they might be hidden under to caps, then remove the acsess cover from the front. From there you should see a control box with six controls, three on top of three,,,,One part label "screen" the other "focus" now turn the set on and tune to a input that HAS NO SIGNAL this should give you a black pix, probley not now but it's supose to be black. Now turn the ones marked screen , one at a time counter clockwise just a little to get the pix compleatly black, now starting with one color turn the control slowly clockwise till the color just appears then turn it back down till it just disapears (Black) do this for all three colors Now the set should runn
