TROUBLESHOOTING 
Common Problems and Solutions 
These guidelines provide tips to deal with problems you may encounter while using the projector. If the 
problem remains unsolved, contact your dealer for assistance. 
Often after time spent troubleshooting, the problem is traced to something as simple as a loose connection. 
Check the following before proceeding to the problem-specific solutions. 
 Use some other electrical device to confirm that the electrical outlet is working. 
 Ensure the projector is turned on. 
 Ensure all connections are securely attached.  
 Ensure the attached device is turned on. 
 Ensure a connected PC is not in suspending mode. 
 Ensure a connected notebook computer is configured for an external display. 
(This is usually done by pressing an Fn-key combination on the notebook.) 
Tips for Troubleshooting 
In each problem-specific section, try the steps in the order suggested. This may help you to solve the 
problem more quickly. 
Try to pin point the problem and thus avoid replacing non-defective parts.  
For example, if you replace batteries and the problem remains, put the original batteries back and go to 
the next step.  
Keep a record of the steps you take when troubleshooting: The information may be useful when calling for 
technical support or for passing on to service personnel.

HDMI Q & A 
Q. What is the difference between a “Standard” HDMI cable and a “High-Speed” HDMI 
cable? 
Recently,  HDMI Licensing,  LLC  announced  that  cables  would  be  tested  as  Standard  or  High-
Speed cables.  
˙Standard  (or  “category  1”) HDMI cables  have  been  tested  to  perform  at  speeds  of  75Mhz  or 
up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.  
˙High  Speed  (or  “category  2”) HDMI cables  have  been  tested  to  perform  at  speeds  of  340Mhz 
or  up  to  10.2Gbps,  which  is  the  highest  bandwidth  currently  available  over  an HDMI cable 
and can successfully handle 1080p signals including those at  increased  color  depths  and/or 
increased  refresh  rates  from  the  Source.  High-Speed  cables  are  also  able  to  accommodate 
higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600). 
 
Q. How do I run HDMI cables longer than 10 meters? 
There  are  many HDMI Adopters  working  on HDMI solutions  that  extend  a  cable’s  effective 
distance  from  the  typical  10  meter  range  to  much  longer  lengths.  These  companies 
manufacture  a  variety  of  solutions  that  include  active  cables  (active  electronics  built  into 
cables  that  boost  and  extend  the  cable’s  signal),  repeaters,  amplifiers  as  well  as  CAT5/6  and 
fiber solutions. 
 
Q. How can I tell if a cable is an HDMI certified cable? 
All HDMI products  are  required  to  be  certified  by  the  manufacturer  as  part  of  the HDMI 
Compliance  Test  Specification.  However,  there  may  be  instances  where  cables  bearing  the 
HDMI logo  are available  but  have  not  been  properly  tested. HDMI Licensing,  LLC  actively 
investigates  these  instances  to  ensure  that  the HDMI trademark  is  properly  used  in  the 
market.  We  recommend  that  consumers  buy  their  cables  from  a  reputable  source  and  a 
company that is trusted.
