Texas Instruments DW30, MATRIX 3000 user manual

Section 3: Operation

•In Single Lamp mode, the projector will try to strike the lamp again in 90 seconds (considered re-strike #1). Only after the third attempt (re-strike #2) will the projector declare the lamp as “Failed to Strike” (in Lamp submenu) and automatically switch to the single lamp operation mode for the lamp that was not ignited. All lamp specific menu options will then change to reflect the true lamp operation mode of the projector.

NOTE: P-VIP lamps, by nature, do not successfully ignite when “hot” and therefore the 90 second wait period is taken by the projector before each strike attempt and between powering the projector down and up again.

Lamp operation modes will also automatically change if there is a failure of one of the lamp related components, such as the lamp driver, color wheel or fan. An error code will be displayed in the status LED or through the RS-232 serial communications log that indicates which component has failed. The lamp status will also show one of several messages that points to the failed component. The lamp in this instance is typically still okay and does not require replacement.

MANUALLY SWITCHING FROM DUAL TO SINGLE LAMP MODE – Switching from dual to single lamp operation mode occurs immediately. The result is an instant dimming of the displayed image. At this time, you can modify the lamp power or adjust other settings to increase desired brightness.

MANUALLY SWITCHING FROM SINGLE TO DUAL LAMP MODE – When you manually switch from a single lamp mode to the dual lamp mode, the projector immediately tries to ignite the second lamp. If the first attempt to ignite the lamp fails it will wait 90 seconds and try again.

MANUALLY SWITCHING BETWEEN SINGLE LAMP MODES – When manually switching between single lamp modes, there is a 35 second overlap when both lamps are on. This overlap allows the “new” lamp to warm up before the other lamp is turned off. The new lamp operation mode displays immediately in the menus. Only after the third attempt (re-strike #2), will an error message display to indicate the type of error that was detected. If no specific error is detected, then the error will be “Failed to Strike”. If this occurs, the first lamp will not turn off and the projector will continue to operate in the original lamp operation mode. In summary, it could potentially take the projector up to 4.5 minutes to successfully switch lamp modes. The projector will attempt to maintain light on the wall during this time. NOTE: If a problem is fixed before the last strike attempt the lamp could turn on.

If a lamp fails during operation, the projector will immediately attempt igniting the other lamp if it’s not already on. Only in this case, will there be a brief interruption in the display.

NOTE: A lamp will naturally decrease in brightness as it ages. Lamp life can also be decreased further by a frequent change in lamp operation modes (number of times its ignited).
