My SNT-7531 is not alive: it has black screen always.

SNT-7531 LCD screen may be black because of next reasons:

1. There is no power supply. See Power indicator placed on the front panel, check power cord connection and power switch button.
2. Analyzer's screen was switched off by operator's inactivity timeout expiring. Try to press Shift key to switch on screen.
3. Screen brightness was tuned to minimum value. Set brightness whell and contrast whell (if exist) to medium positions.
4. LCD was switched off by front panel buttton. SNT-7531 analyzers shiiped with ACME portable cases, which equipped with LCD off button. Pressed button state means LCD is off. Try to unpress button if it was pressed.
5. It is a LCD display mailfunction. Connect external monitor via VGA socket (placed on a left analyzer's system block side). Maybe, you can work with analyzer until LCD will be repared. Report this problem to Technical Support anyway.
