Couple of simple methods: 1) The metal bezel that supports the glass is usually connected to Vss. Quick check with an ohmmeter should tell you . . . 2) connect ohmmeter in "diode check" mode across the two pins you think are Vss & Vdd. One polarity should show about 0.7V drop, the other polarity should show much higher - possibly even open. The higher reading shows the correct polarity. dwayne -- Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 20 years of Engineering Innovation (1984 - 2004) .-. .-. .-. .-. .-. .-. .-. .-. .-. .- `-' `-' `-' `-' `-' `-' `-' `-' `-' Do NOT send unsolicited commercial email to this email address.
