It is for sell in Craigs list offered "as is". They claim lamp, but I am skeptical because user's guide says light blinks five times for faulty lamp and should not be able to power on. This model powers on and then automatically shuts down and then comes back on. Is this fan, thermal relay, color wheel, any clues out there? |

If the television is more than 2 years old and if they haven't change the lamp before... then it is most likely defective Check this link to learn more on the bulb: http://www.discount-merchant.com/how-dlp-works-like-magic-a/141.html Maybe you didn't bought the TV but if you're still looking for a used DLP set, try checking if a local store is selling it that way you can check: >Picture and audio quality >Ask how old the TV is >Ask what kind of problems has the TV experienced >Ask if the lamp, color wheel or the ballast have been replaced (or any other component) >Check if you hear any humming or buzzing noises (symptoms of a faulty ballast) >Check for any whirling or winding sounds (symptoms of a defective Color wheel) >In case of a dark picture adjust the picture settings, if the screen is still dark then the lamp may be in the end of its life >Check the store policy, check the warranty and get a copy of it. If everything looks OK then give it a shot, but if the TV is offered online (like in this case) then I wouldn't recommend it.
