Install new lamp, nothing comes on ,change back to old lamp still nothing


Hi,If the lamp didn't do the work it could be that the problem is with something else.If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Do you hear buzzing or high pitch sounds? If you do it could be a problem with 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.Make sure the door cover is properly shut other wise it wont lamp light up.

My picture won't show after replacing the lamp


Actually that humming sound was not the lamp, the humming sounds come from color wheels when they're going out, and since the color wheel is part of the light engine system and it's not working, that's why you don't have an image, you'll probably ask your self why, since it's not the lamp.. the thing is that the light engine system is componed by lamp, ballast, color wheel and dmd board, so when one of these doesn't work, there will be no image reflected, because they work together

Samsung hlp 5063w humming noise


Can you reseat the lamp?  Don't forget to unplug the TV of course, but sometimes the connection between the lamp and TV degrade due to heat contraction and cooling.  Some TV's provide an error code by having LED's flash a certain way, is this what you mean by lights flashing?

the buzzing noise you are hearing is from the lamp ballast as it strikes the lamp. that is quite normal but it should only be momentary. it should not be constant.

Hi, I would suggest you exchange it for a new one under the 6month warrranty it has.

I have several iHome Lamps and I dont have a humming noise from any. I know its annoying but its an electrical item and sometimes they go wrong.
