We have had the lamp replaced. Now we are experiencing a buzz and flicker when watching TV. It sounds like a fan going out? It is extremely loud. We turned off for fear of damage.
Their is no more you can do. You need a professional. Stop using the TV until it is repaired. Call the manufacturer to find you nearest authorized service center.

Linda .....no its not the lamp thats causing the whirring/buzzing sound but the colour wheel, its housed in the light engine you will need to replace the whole light engine cos the inbuilt colour wheel is worn out this causes the buzz hence the lamp may not light up or u may have shut downs flickers on the pix or color issues
Yes, loud pop sound was broken lamp in tv, replacement of lamp will fix tv problem. Lamp replacement procedure is easy and would be written in user manual. Please buy Sony original lamp for good picture in tv. Thanks.
Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner. Contact local tv repair shop to get color wheel replaced in tv. Thanks.
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.
There is a fan beside the lamp chamber in this TV. There should be 4 fans total, and the one beside the lamp chamber might be making some noise. They are all bearingless fans, so the noise should be relatively low-pitched "whirr" if it is the fan. If the noise is more of a buzzing sound, it could be coming from the lamp driver (ballast) or from the lamp itself. Lamps tend to do strange things toward the end of their life.
If you have never changed the lamp, it is about time. They have a 2.5 -3 year life span with average use.
One thing you can try is to turn the TV on from a cold start, and watch inside the vent areas beside the lamp chamber. If you hear the noise before you see the lamp light up, then it is probably a fan. If it starts as soon as you see the lamp light up, it is the lamp or ballast.
There are only 2 moving parts on a dlp tv the color wheel and the fan. The color wheel needs to be replaced about every 4 to 5 years. Some start to make noise and others like mine blow up with a bang. Go to utube to get instructions on how to replace it only cost me for part $100 good luck
The sound is a result of the faulty CRT base, and you will have to replace the base socket. Make sure you by the exact same type of base, and if you are not a techie, get a qualified technician, this is not a costly problem.
since you changed the lamp my next thought is that the color wheel has failed,,,most good road techs can replace it in the home..the cost would be between 220.00 and 350,00 depending on the company...
