Repair your projector
We can restore your projector to its full
functionality. Based on our experience, projectors which
are heavily used can suffer from power issues, cooling issues, and
image discoloration. Whether the unit needs new
polarizing filters, mirrors, fans, or bulbs, we can help. We are a
service center for Panasonic, Sanyo, and Eiki, Sony, NEC, Epson, Dell, Barco,
BenQ, Optoma, InFocus, and Christie Projectors. We
especially recommend repair for high-lumen projectors, as these
units are very expensive to replace and are built to last.
Don’t Replace your Lamp!
Many repairs come to our facility after
the owner has attempted to replace the lamp, only to find that the new
projector lamp did not improve prior issues. Sometimes, users may attempt to
replace the lamps with cheap lamps – these lamps can cause power fluctations that damage internal components and cause
more damage over the long term.
Common Projector Repair Issues
Discolored Projector Image
Projector image discoloration is one of
the most common issues, and is not resolved by replacing your
projector lamp. If your projector shows a yellow, red,
purple, or blue tint along all or part of your image, it needs to be professionally
serviced. A discolored image means that there is an issue
with the color wheel (DLP
projectors) or polarizing plates (LCD projectors). If
caught early on LCD projectors, this repair only requires cleaning, labor, and
recallibration of the color module. If you wait too long,
this repair involves replacement of the polarizing plates or prism assembly
which can be quite expensive.
Dust, Specks, and Dark Spots on Projector
Projectors require cleaning and
maintenance. Failure to do so on an annual or semi-annual basis can lead
to dust within the optical section which will show up as dots or specks on your
projector image. If the dots are a tinted color or hue, this means that
the dust has settled on the color module, which means that the polarizing
plates need to be cleaned (lcd projector) or the color wheel needs to be
cleaned (dlp projector). Less commonly, this could also be a result of a
damaged dlp chip (from being dropped or otherwise), or a damaged section in the
prism assembly or optical block.
Projector Won’t Power On & Other
Projector Power Issues
If your projector unexpectedly shuts off
or won’t power on,
there may be an issue with the power supply,
ballast, software, or cooling system. In some cases, there may
be damage to the
internal circuit boards. This repair will involve
pinpointing the cause of the problem, along with a thorough cleaning of hard to
reach cooling channels. This is not a user serviceable
Projector Has Blinking Light
A constantly blinking green or red status
light may indicate one of a few system messages.
Depending on the make and model of the projector, a blinking status light may
mean it’s time to replace the lamp,
the projector is over-heating, or needs
to be cleaned. If the status light is accompanied by a
power-on issues, then this may be indicative of more significant issues such as main
board failure, ballast failure, or needs replacement fans.
Part of Projector Image is Black or
If you have a DLP projector, a broken DLP chip is the likely cause and will require a
replacement. On all projectors, this could be the result of damage to the prism assembly or optical block.
Projector Image is Dull or Dim
The likely culprit of a dim projector is
the bulb. High bulb hours will require a replacement of the bulbs in the
unit. While replacing the lamp can be done by the end user, it is
important to realize that the lamp is usually one of the last things that needs to be replaced.
We recommend replacing bulbs after 3000 hours of
use, which is well outside the annual use range for most recreational projector
users. Often times, we receive calls from customers who have spent a few
hundred dollars replacing their lamps, only to find that the lamp was not the cause
of their discoloration, power on issues, or blinking status lights.
Some projectors use more than one lamp, such as the such as the Sanyo PLC-Xf46,
which uses 4.
Quality lamps can be quite expensive and
we recommend only replacing the lamps when needed. Just because a website
claims that they sell lamps does not mean that those lamps are original
quality. These lamps have been known to cause power fluctuations, leading
to power supply failure, ballast failure, or even main
No Inputs Recognized by Projector
The issue could be either software or
hardware. Try switching to a different input,
for example, use your laptop to plug into the VGA or HDMI port you previously
were not using. Make sure that your projector is on the right
display mode. Sometimes, broken remotes or broken buttons
on the projector will prevent you from switching to the correct input, so test these
too. If you have confirmed that the projector’s hardware or software is the
cause of your input issue, it is likely that the interface
board may need replacement.
Cracked Projector Lens Assembly or
Mishandled projectors that have been
dropped may need work to replace physical features of the projector, including replacement
of any mounting brackets for lenses, or the lenses themselves. Lenses
are not repaired, but they are rather replaced.
Preventative Maintenance for your
Preventative Maintenance will increase
the lifetime of your projector. For schools and businesses
using projectors, especially high brightness projectors, a good Preventative Maintenance schedule calls for a
cleaning and re-calibration once a year.
