5.1 General Information
This chapter provides information and solutions on probable projector problems,
including Error Codes, Power-On Codes, and Break Points for HJT Model 330,
Model 340SC and Model 370SC Projectors with software version 5.1.0.
The Error Codes listed in Table 5-1 describe possible problems associated with
software and hardware while the projector is operating. The first (1
st
) column of
the table lists the LED letters shown on the rear of the projector, and the second
(2
nd
) column for the first seven (7) letters shows the on-screen text that shows
along with the operator messages (up to 19 characters). The remaining codes
appear without on-screen text—the second (2
nd
) column is the error description.
Status or error codes are flashed for no more than one (1) minute before being
replaced with the neutral beating “0” (zero) at a low light level.
The Power Codes in Table 5-2 show the sequence of codes that occur when the
projector power is first turned on. The first (1
st
) column indicates the LED code
letter or number and the second (2
nd
) column provides a description of the
problem.
Break Point (Trap Processing) Error Codes and Break (Trap) Data Code Displays
are detailed in Table 5-3 and Table 5-4.
The Menu Structure Diagram provides information about the Projector Menu Log
that will help to determine if certain assemblies are due for replacement.
Table 5-5 provides a Troubleshooting Guide to possible problems encountered in
the Model 330, 340SC and 370SC Projector. The first (1
st
) column calls out the
nature of the problem and a possible symptom to check. The second (2
nd
) column
suggests possible solutions. The third (3
rd
) column provides the reference section
in this manual. The fourth (4
th
column supplies the reference section in the
appropriate model Operator's Manual.
