57H84. (Don't know if it is a 57H84C, 57H84R, or just 57H84). Colors are fine for well lit or daytime backgrounds Low light or nighttime pictures loose the picture in the background. All that is seen are the faces. All other color fades into the darkness of the picture. The picture then looks like people are visible due to candlelight only. Can this be repaired or is it time to get a new TV

Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck

Take out the lamp and clean it. Look inside where the lamp was and you will see a thin peice of coloured plastic (colour wheel). Vacuum that plastic and all around it but don't touch it. This solution worked for me, and now my TV is as good as new.

If you are using component cables make sure they are all connected properly( pushed all the way in and in the correct input). I have seen the red cable come loose several times and cause no red color in the picture. When you change the lamp it is easy to pull on one of those cables and cause it to come loose.

this a problem with the motherboard. not the lamp.

SOURCE: TV picture is red.

Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.
