JVC DLA RS40 lamp hours

Bigsquatch

I have the users manual for this device and also the

JVC D-ILA® Remote Control Guide (http://support.jvc.com/consumer/support/documents/DILAremoteControlGuide.pdf">JVC D-ILA® Projector RS232 / LAN / Infrared Remote Control Codes)

but neither of them contain any reference to getting the lamp hours from the device via RS-232.

Anybody here know of an undocumented command to get the lamp hours?

John Gonzales

The older JVC's used to use 'U1C' command. The response would be a hex # which you would divide by 15 to get the hours. In other words

SEND_STRING dvPROJECTOR,"'?','1',$20,'U1C',$0D"

Response for 100 hours might be something like
@1 0 05DC 0 $0D

Where $05DC divided by 15 (decimal) = lamp hours
and the 0 following the lamp hours indicates that lamp doesn't need to be changed (1 = replace soon, 2 = lamp life exceeded)

The following was used to reset the lamp counter
SEND_STRING dvPROJECTOR,"'!','1',$20,'U1C',$20,$5B,$28,$29,$5D,$0D"

Not sure if these commands are still supported but might be worth a shot

Thanks! I'm on site today and I will try that.
