I just attempted to calibrate the probably similiar Toshiba 19SL410U with LED backlighting. Although it appeared to have a complete and working CMS in the advanced user menu, there are no apparent GS/white balance controls. The white balance is way off especially at the high end of the GS with a DE of over 25 at 100%. I also have been unable to enter the service menu to search for white balance controls.
