Probably a dirty or failing fan, check and clean all fans, look at the color wheel and inspect for damage (if you have one)

PHILIPS 50 Inch HD DLP Projection TV the picture went out suddenly and there is not sound but a loud humming-buzzing coming from the set...any ideas on what could be wrong or if it can be fixed?


It's the optical block (color wheel) and the same thing happenned to our Philips 50" DLP. From what I've read, it's not worth the trouble & $$ to fix. Dig a hole!

Loud humming sound on with a purplish and pinkish screen on my 50 inch dlp samsung, 5 yrs old.


Hi,sounds like you might be experimenting a color wheel problem.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.Your part # is BP96-00250A You can find it here http://www.discount-merchant.com/Samsung-BP96-00250A-ColorWheel-Assembly-p/bp96-00250a-color-wheel.htm?Click=48173 and here's the instructions to replace it : http://www.fixyourdlp.com/guides/samsung/bp96-01579a.php Have a bless one!

Lamp won't come on and loud rattle in back of tv


Probably a defective color wheel. The bearings are bad or perhaps the wheel itself is broken.

My Samsung 50" DLP HDTV keeps humming when the DLP lamp comes on.


Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek
