Need to replace- looking for a package insert to identify the wires exiting the back of the switch


Brand of dimmer? All my Lutron dimmers have 3 or 4 wires, and if it's a simple stand alone, it's two black wires and a green one. green is ground, the others go one to hot, one to the lamp.
If you have a white one and a black one, black is "hot", white goes to the lamp.

Lg 56dc1dab dlp projection tv is now in black and white? The lamp indicator has been on for a while. Is the colour gone due to further damage or can we replace the lamp and fix the colour?


lamp going out should not cause color to go out. I would check all connecting cables at both ends to be sure that is not the color issue.
Be sure you did not accidentally turn color down in trying to adjust video controls due to weak lamp. Then replace the lamp.

Black screen with sound. we replaced the lamp but screen is still black.


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 Hi,If your tv is a dlp 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. Also make sure everything is properly closed (door cover) if it's not properly shut it won't be able to light the lamp.Have a bless one!

How to wire up an E40 ceramic lamp holder for use with compact flurescent (sic) or high intensity discharge lights? (GENERAL ELECTRICAL KNOWLDEGE) Lights are used in factory High & Low Bay lighting;...


If this is being used as a socket for a 120-volt lamp (such as a compact fluorescent with self-contained ballast or an incandescent lamp), you wire the black (hot) AC line conductor to the brass-colored screw and the white (neutral) conductor to the silver-colored screw. If the socket is equipped with pigtails instead of screws, use pressure connectors (wirenuts) to connect black to black, white to white.

If you are using HID lamps, you don't wire directly to the AC line. These lamps must be used in a fixture with the correct ballast transformer, capacitor and ignitor (for pulse-start lamps) for the lamp wattage. If you are replacing the socket in such a fixture, follow the wiring of the old one when installing the new socket.

My InFocus 4805 SP projector is showing just black and white


If you have any video at all and it's only Black and white there is a 99.99% chance that your Color Wheel has lost all of it's glass color filters.
You can confirm this by removing the lamp. then look straight into the projector where the lamp was and you should see the color wheel of colored glass segments (Red, Green and blue) I believe you won't see them because they came off of the wheel.
Also if you lift up the projector and turn it around in various angles and you will hear the small pieces of broken glass from the color wheel.
Unfortunately you will need to take it to an authorized service center for repair. Be prepared to spend upwards of $300 for the repair.

Cheers

Service man says light engine. how much? jvc model hd52g886


Whites are yellow can be a convergence or color balance problem, and lamp going out could also be a bad ballast board, black spots are usually light engine, could be a different fault on DMD board.

The fact is that when you get all this symptom together unavoidably you have a faulty light engine.

The light engine is the most expensive part to replace, its price for this model is always over $1600 ( I know, keep the heart tablets at hand).

Here is the part for your model: TS-COP7A-SAA-R

I heard a pop and now the projector only shows black and white.


The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.
