Question about RCA Televison & Video
That set uses a color wheel on a high speed motor and a ballast to power the lamp. It is hard to guess at this point what it is without further info.

There is a stand up coil about 1" tall and the dia of a nickel close to the HV transformer, the iron core glue comes loose over usage. This can be cured by replacing it or using a sealer/caulk and re-seal the coil. Hope this helps, it is not an expensive job for service.

first check all fuses they are small, square ,RED and can be confused with the square small caps. the sizzling is prob. the flyback transformer (what the h.v. wires from each tube plugs into) if you are only getting green then tv shuts down or is dead now. i would replace any bad fuses and replace the flyback transformer. also make sure you do a very good visual inspection of all the boards.

It sounds like there is definitely a short in the unit. If it turns off immediately it is probably the low voltage power supply that has the problem. If your unit is 6 or more years old and the lamp has not been changed I would do that first. I have a tip at http://www.fixya.com/support/r4168009-change_lamp_in_dlp_projection_tv which explains how to do this and where to get the parts at the best price. If changing the lamp does not work I have a tip at http://www.fixya.com/support/r4606286-troubleshoot_dlp_tv which explains how to troubleshoot a dlp tv in terms anyone should be able to follow. Let me know if you need more assistance.
Thanks for using FixYa and for the generous rating.
