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.

I am working on the exact same problem with the same symptoms. Make sure the tv is unplgged for at least 5 minutes before poking around. The power cord can be unplugged from the power board and removed to keep anyone from plugging it in while you are working on it.
The STK's are the large 18 pin integrated circuits (chips) mounted to the large heat sink on the convergence board. This is the board on the right when viewed from the back of the TV.
The resistors are beneath the heat sink on the left side of the board. There are also fusible resistors, like #7711, on that side. There are NO pico fuses in this area.
Fuse 853 is on the Power board. This is the board on the left when viewed from the back of the TV. You can remove both boards in the carrier by carefully unplugging all connectors, noting their locations and routing.
To remove the high voltage wires from the splitter, mark them for position then grasp the boot and turn counter-clockwise about 10 degrees to unlock them and then pull up while holding the High voltage splitter. The small high voltage wire can be removed from the flyback transformer by pulling hard while holding the flyback.
STK392-110 can be replaced with STK392-120, STK392-180, STK394-160.
I have found most of the parts at newark.com. Also check out this site for some very good info: http://www.hometheatershack.com/forums/diy-repair-maintenance/5600-crt-based-rptv-convergence-repairs.html
btw: I am not affiliated in any way.
Make sure that while you have the boards out you look for any bad solder connections. A lot of problems arise or return because of this.
I hope this helps, I have been doing a lot of searching to get this info and hope it helps you. Too many people want to trickle the info and pretend they are giving you gold. A few hobbyists or people that can't afford to pay $300+ for repairs are not going to hurt their business.
Be safe and share knowlege freely!

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php The ballast is the most common failure besides the lamp.The ballast is the one that displays the lamp indicator if it's not able to power bulb or if bulb is not responding.Have a blessed one!
