Mitsubishi 915B441001 Assembly instructions

Here are some 915B441001 quick troubleshooting tips for your Rear
Projection TV lamp installation
After installation, lamp will not fire, ignite, or turn on
1. Make sure the TV is plugged in and there is power going to the outlet
2. Open the lamp door, reseat the lamp housing unit, then firmly close and secure the Lamp
door
3. Reset lamp timer(if applicable)
Listen for sounds form your television, and check for indicator lights as there may be
something else wrong with your TV. If there is no power to the unit at all, there may be a
power supply issue. Other components like a defective color wheel or ballast can also cause
TV malfunctions.
I see blinking indicator lights on the TV
A blinking indicator light, or series of lights, may be caused by other failed components and
does not necessarily mean the lamp is bad. Please refer to your TV owner’s manual for more
information.
I hear a clicking noise or a low humming noise
The clicking or humming noise is most likely the ballast trying to power the lamp, but failing.
This may indicate a defective ballast if you have recently purchased a new lamp.
It’s highly unlikely for a new lamp to be dead on arrival (DOA). A rapid, steady, or irregular
clicking noise may also mean that the ballast isn’t securely connected to lamp.
I hear a whining, whirling, or screeching noise
(TVs using DLP technology only)
A loud whining, whirling, or screeching noise is most likely caused by a defective color where.
Symptoms also include a dull, blurry, or distorted picture. A bad color wheel can also cause
lamp indicator lights to blink and prevent the TV from powering on.
The lamp looks different than the original
You may have a newer designed lamp housing unit, lamp enclosure or lamp. If the lamp unit
does not fit properly into the TV, please contact the vendor for further investigation. It is
possible that you may have ordered the wrong part. Some OEM parts may have changed
slightly, and some aftermarket replacement parts may look different.
Always be careful when servicing your TV.
To reduce the risk of fire, electrical shook, and other injuries, practice safe methods when
installing, using, and maintaining your unit.
Risk of electric shock!

It is recommended that you unplug your TV and ground yourself before installing or
troubleshooting. Please refer to your original TV owner’s manual for safety instructions.
Risk of fire!
The high voltage components in your TV can cause a fire. When installing your lamp, make sure
all connections are properly secure. Please refer to your original TV owner’s manual for safety
instructions.
