Have NEC LCD1850X that has unlit screen. Have briefly checked the power supply, and I do have around 160V at some place in the power supply. I do not see any lamps lit but not sure if I should without complete disassembly. I do not have schematic so if anyone knew where I could download one it would be a big time saver. Any other hints would help also.
Many thanks,

Usually dont need schematics for LCD If the power supply doesnt fix it the costs become prohibative. Check the supply, replace all the electrolytics check high value resistors and its done. Also make sure you discharge the mains filter before you measure things as if its fully charged you can destroy things by testing.
