Pioneer CDJ800 laser current check

Hi,

anyone know how to measure the laser current in the Pioneer CDJ800 Mk1? What is the generic method for measuring laser current, if there is one? Also, is it possible to simply replace the laser in the CDJ's, or does the firmware have to be recalibrated etc?

Here's the procedure for the CDJ800 Mk 2:

"LD current: 20 to 80mA : TYP : 40 to 50mA Measure both end of R249 on the MAIN Assy in the play state. There must be the value that divided the measured value with 23.5 Ohms within the numerical value mentioned above"

Cheers,

Gareth.

Ah, just found that although the laser assembly is not the same, the Main PCB and measurement procedure is.
