Question about Projection Televisions
SOURCE: Picture then fades to blue.
I just fixed mine. I read other posts that suggested this and it worked. On the front of the set at the bottom of the speaker cover are 2 caps, one on each side. Remove those caps to find 2 screws, remove screws and then remove that cover. Behind that is a panel with 4 screws and remove it. You will see a box with 6 knobs, 3 on top 3 on the bottom. Top are focus and bottoms are voltage to each lamp. Blue lamp is left screw, green lanp is middle screw and red lamp is right screw. Counter clockwise lowers voltage(very small adjustments. So if your screen is turning blue turn the left screw just a littleat a time. I also had red and blue lines on my screen so i turned them a little as well and they are gone. Give that a try, it worked for me.

First reduse the G2 voltage for the blue c.r.t,and watch if the unit works for longer period (offcource blue colour will be not present).After reducing G2 voltage to blue c.r.t still behaves the same than c.r.t is faulty and you have to replace.
Pls count the red led blinking when it goes off,incase it goes to std by mode.

Here is what you need to do.
1.) You need to remove the entire plastic piece below the front of the screen. You most likely will find 3 screws on either side in back that you have to remove.
2.) The grill will not come out easy, pull from one side and then when it starts to come loose from the other side(there are several plastic pegs that hold it in.) Then from the bottom pull out( most of these sets have square plastic tabs at the top that tuck in.)
3.) With the grill removed locate the inspection plate behind it (it usually has 6 screws.) You will have to tilt the grill to the left and on its side as several cables are connected to it--they are held in place with trash bag like ties that you can release to get some room.
4.) With the inspection plate removed you will see a fairly small (about 3 inch square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with whiteout so someone can tell if they have been adjusted.
5.) You need to look very close at the block with a flashlight----usually the top three controls are FOCUS--don't touch those.
The lower three are usually marked Screen and if you look very close you will see b, g, r(blue green red)
6.)Usually the blue will be on the bottom left--it does vary
7.) Once you locate the BLUE screen control have the set on and turn it down--if the set is shutting down you may have only a few seconds to try to turn it down---usually to the left with the Blue Screen control.
8.) Best way to do this if the set is on is on a video input with nothing connected--you turn the blue down until the set stays on and then very slowly turn it up until you see a slightly blue screen with or without diagonal trace lines----if you get it to turn on this way turn the blue screen back down slowly until the blue screen and trace lines just disappear.
Let me know if you get it to work--Like I said if it is shutting down you may have to slowly turn the blue screen down a few times to get it to stay on.
I do this here for free and if this helps you at all give me a vote here--it costs you nothing.

Testimonial: "Great detailed instructions. TV works great now. So far so good. Thank you Steve."
I had the same problem. I got the service manuals, did some troubleshooting and figured out that my DM3 is bad. I'm trying to track down the details.
