FAQS

TV Lamps

 

What is the housing?

The housing is the plastic cage or cartridge that surrounds the lamp and holds it in place in your TV. When replacing your lamp you will first remove the housing unit from your TV then remove the lamp from the housing and replace it with the new lamp. The housing may slide out of the front or rear of your TV depending on the make and model. See your owner's manual for directions on removing the lamp housing unit.

 

Is it difficult to replace the lamp?

Replacing the lamp is a simple procedure similar to replacing an ink cartridge in a printer. You'll need to locate the lamp door on the back or side of your TV, open/remove the lamp door,  slide out the old lamp assembly and replace it with your new lamp assembly. In most cases all that is required is a Phillips screwdriver and about 10 minutes of your time.

 

How long should my lamp last?

Television lamps are rated for 4,000-6,000 hours of use which is approximately 1-3 years depending on usage patterns.

 

How can I extend the life of my lamp?

Prevent damaging voltage spikes. Plug your TV into a quality surge protector.

Let the lamp cool down. After turning off your TV let it remain off for at least 30 minutes before turning it on again.  This allows the lamp to cool to room temperature.  A cool lamp is more resilient to the large voltage burst required to ignite the lamp when the TV is turned on again.

Keep it clean. Extend the life of your lamp by keeping the area surrounding your TV/Projector well ventilated and dust free. 

 

My TV has white and/or black dots on the screen

Are you seeing spots? If there are black or white dots on your TV screen a component of your television called the DLP chip may be failing. The DLP Chip, or digital micro-mirror device (DMD), is an optical semiconductor that is the core of DLP projection technology.  Every pixel on a DMD chip is a reflective mirror. The mirrors tilt rapidly toward and away from the light source (the lamp) which, in combination with a high-speed color wheel, produce the color structure of the projected image. The black/white dots on the screen are caused by one or more of the micro-mirrors on the chip failing to operate. The problem can be fixed by replacing the DLP chip.

Lamp Installation Precautions

Don’t touch the glass surface of the new bulb.  Touching the glass will deposit skin oils onto the bulb’s surface.  When the lamp heats to its operating temperature the oil will cause a temperature difference on the bulb’s surface that may distort the picture and can cause the lamp to break.  Handle the lamp assembly by using the designated handle (if applicable) or touch only the plastic part of the housing.  If you touch the glass lens of the bulb clean it with a lint-free, smooth, dry cloth before installing. 

Don’t overtighten. If you ordered the bulb only, take care not to over tighten the screws when replacing the bulb in the housing.  Finger-tight is sufficient.

Put it back together. Prior to turning on the TV/Projector after lamp replacement please ensure the lamp assembly is situated properly and the lamp door is closed and secured.  Many TVs have a sensor that will keep the TV from turning on if the panels are not replaced.  Often times, if the lamp is installed improperly, a flashing yellow light will appear.
