Was watching the projection and everything was fine. Then a loud pop/glass breaking sound was heard. Immediately, the projection could only be seen in black and white (no more color images). Help!

A capacitor has failed, common problem, easy for a TV guy to fix.

DLP type sets regardless of brand all have some things in common--use a lamp, a Ballast, etc.

If sound you need to see if the lamp is coming on when set is turned on--usually in these type sets if no brightness one or more lights on the front of the set will be blinking---no model number is indicated with this question..

If you had a picture, even briefly, after the sound you heard then in all liklihood it's the color wheel that broke. Not a DIY friendly project unless you're very good with electrical/mechanical repairs, especially small fragile items :(

Your lamp burst. This model uses a lamp housing which does not have a filter screen on it. When the lamp bursts, hot pieces of glass and mercury (very toxic) drop straight down into the cooling fan below it. Although FixYa.com (implies I'm suppose to tell you how to fix it) I am going to tell you to call a servicer and have them clean that mess out of there. It's a health issue, I don't want someone unknowingly exposed to mercury on my watch. Let the servicer know what he is getting into. I hope this helps.

If there is no picture but sound is audible then replacing the projection lamp will do otherwise, the TV requires to be diagnosed for any other hardware damages.

If you have a Sony DLP, then the loud pop you heard is your lamp.  The lamps last approx. 4K-6K viewing hours.  Read your manual for replacement part number to reorder and very simple to replace yourself.

Following up on my Feb 7 post. My new lamp arrived, and I replaced it and it works great. The old lamp had many shards of glass come out of it. It was tore up. I saved some money buy purchasing just the lamp and not the cartridge. It's a little bit more work to take apart, but saves money. Mitsubishi wanted $289 for the lamp replacement kit. I got a lamp for $114. TV is working just fine now!

sounds like the lamp has shattered. check the lamp

possible convergence amp ic's failed should be under $300.
