Error code
There are some internal error codes here.
Error code 0 means No failure or unknown failure.
Error code 1 means overheating failure.
Error code 4 means outer fan failure on the front cover.
Error code 8 means blower or fan failure on the optical engine.
Error code 16 means central fan failure on the front cover.
Error code 32 means color wheel failure.
Error code 128 means lamp failure.
Example. If error code is 144, what we know from this?
Step 1. Change the 144 to 10010000 (decimal to binary system)
Step 2. 10010000 combines from 10000000 or 00010000.
Step 3. Convert 10000000 and 00010000 to 128 and 16 (binary to decimal system) respectively.
Step 4. So we know that this device has ever happened color wheel and lamp failure from the last
reset all setting. But we don’t know which events happen fi rst.
Shipment Reset
Let all parameters go back to default. This reset is much more powerful than the factory reset un-
der the end-user interface.
FAN1
Control the outer fan on the front cover. Keep the default value. Don’t change it.
FAN2
Control the blower or fan on the optical engine. Keep the default value. Don’t change it.
FAN3
Control the central fan on the front cover. Keep the default value. Don’t change it.
Test Pattern
Choose the Burn-in pattern or ADC calibration
Thermal 1
The thermal sensor has ever detected the highest temperature from the last reset all setting.
Thermal 2
The thermal sensor has ever detected the highest temperature from the last reset all setting.
BurnIn Cycle
How many cycles to run the burn-in pattern chosen under Test Pattern.
CW index delay
See “C/W DELAY ADJUSTMENT” in the ELCTADJ fi le.
Lamp total hrs
How many hours this machine works?
Lamp current hrs
How many hours this lamp works?
Note:
S-Video or DVI source do not need ADC calibration.
CW index delay, Lamp hours, Thermal1, Thermal2, Error code will not be infl uenced by update fi rmware.
LIFE TIME OF THE CONSUMABLE PARTS
Following are the reference of the life times of the consumable parts.
