Check the lamp to see if the pop was the filament breaking. the whirring could be the ballast trying to fire the lamp.

TV made a big popping sound, and then a crackling


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php That crackling sound could be of the color wheel:The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9601073A you can find original here:http://www.discount-merchant.com/Samsung-BP96-01073A-lamp-p/samsung-bp96-01073a-lamp-oem.htm?Click=48173 .Have a blessed one!

The fan intermittenly makes a noise and the color changes on the tv


You need to give model #. Most likely you have a dlp tv and its not the fan but the color wheel that spins at very high speed and creates correct colors on your screen. This color wheel makes noise when its bad and colors go off when its running at slower speeds. Its going to fail sooner or later as its going bad now. Its a professional job to change the color wheel and could cost you $280-320 depending on the model. Fan generally never make anoise that is loud enoug to be heard unless its blades are hitting some obstru ction. Color wheels make whining or in worst case screeching noise when bad. check out www.fixurtvs.com for more FAQs. Thanks if you voted for me.

Screen went B&W and I hear a loud humming noise from the TV...


Hi John,

If you are hearing this noises,that's your Color Wheel.
The reason fot that is because your color wheel spins 5000rpms(revolution per minute) and something that modifies the balance if the disc can cause different things.Unfortunately in order to check if your color wheel is working properly you need to open your TV and physically check out.

Grinding= Most probably the color disc is broken and you need to replace it.

Spinning / Buzzing = The bearing of the wheel is loose and is loosing its balance,eventually it will brake.

The best thing to do is to take the color wheel out and spin it ,if you feel that the disc kind of wobbles or doesn't spin smoothly you have to replace it.

You can check DM they have very good prices

Sounds like the color wheel may have also gone bad. I recently saw a 56" Samsung where the bulb and color wheel went at the same time. The color wheel could produce a crying noise while trying to spin up.
