SOURCE: my tv is new I plugged it in does it take awhile

If this isn't performing the way it did on the display floor. Please take it back. My thoughts is that the lamp already went bad.
I'm sure it's under warranty and I would get it replaced or repaired right away.

SOURCE: Where does new bulb for picture go inside the TV?

The bulb is in the front of the TV. Remove the front lower cover by pulling oneside at a time. There will be a lable next to the cover for the light housing.

SOURCE: for a while there was

Hello sir, hi, this requires that projector be checked, to fine the whining sound this requires disassembly, or have the unit checked for loose fan blades by a technician, and find that whining sound. If not replacing the bulb is useless, the bulb will always blow up.

There is sound but no picture

The board that connects to the bulb is the ballast. If it's bad then it won't fire the bulb or will cycle it on and off.

Y wd-73c9 tv trns on no picture just a clicking noise when turned on

The color wheel spins at 10,000 rpm so there's a good chance that the bearings will go out, the heat and burnt on dust that gathers on the lenses and the class panels will be enough to cause mayhem with your color wheel. All the parts inside the light box need to be cleaned at least 1 time a year to keep it working properly. Much care must be taken when doing this it's very easy to destroy the wheel if it falls to the ground it's done. I suggest cleaning it over a carpeted area and keeping it on the floor while working. Place a piece of newspaper down over the carpet to keep fibers out of the area. Anything that gets sealed inside the area after cleaning will be burned onto the lenses and the problems will not be cured.

Picture is dark

did u touch the lens or bulbs when u cleaned it? It could be a color wheel problem but i think u should try to reset light tunnel. Did it give you any warning? or did it just all of sudden go dim. I gave u a link to a trusted YOUTUBE tech.. i use his work all the time.
See if any blink codes come up if u disconnect a bulb..good luck

Recentley my tv just turned off. I heard a buzzing sound which happened the 1st time my bulb went out. So I ordered a new one. When the new one was put in it worked for 5 minutes then turned off and...

This could be a couple of things. Look at the cooling fan and be sure that it can spin freely. If it is stuck, the buzzing could be the motor trying to spin the fan. Other than that, the ballast could be failing as well. This is the part that "fires" the lamp. Examine the fan first and let mw know what happens.
