I'd just replace my lamp just three days ago and the problem still

It is probably the wiring. Try buying a new power cord.
If not than it is just malfunctioned.

If the soda got into the inside of the TV it sounds like it has damaged the light engine. There is currently one on Ebay for $400. It unplugs and new one plugs back up. Do a google search with model WD-65733 and verify if this is your model. Otherwise look at the screen closely to see if the soda is on it. On the other hand if you get the light engine out you may see soda spots on the projector and you could just clean it.

riddic759546,

Sounds like you have a bad optical engine. I have a tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine which should solve your problem.

Thanks for using FixYa and for the great rating.

Lamp could be the problem or Ballast board that powers Lamp on. Encompass Parts Distribution visit their website and look up your Model#
If Problem is Lamp Mats has them for $99.00

check your lamp door interlock switch.

What it sound's like is that the lamp ballast is the problem. Buzzing sounds like when the power is first brought to the ballast it has to ramp up the voltage to get the lamp to light, then the voltage drops back down when the lamp is lit. Sounds like the lamp ballast isn't ramping up the voltage the way it should. May have to replace it. A good service shop would be able to do this for you.

put back your board its a cold solder from CRT socket board and the main board. if not check your tuner.
