The TCON Voltage Source will always be provided from the Main board However, the Main board does not actually generate the TCON source voltage All the Main board does is switch on and off the voltage coming from the Power Supply The Power Supply generates a 12V supply that is sent to the Main board.

It is called so because it output voltage much much higher than its input voltage and can easily take in 30 to 50vdc and put out some thing in the range of 100 to 170vdc to drive a very large string of leds. Most likely the Tcon board BNA (V315B1) is creating the problem It cost around US$60 including postage which is on the high side considering the age of this model Changing the Tcon board can be a very fast & easy repair job but it is not cost effective or may not worthwhile to repair it. The receiver detects the polarity of the voltage drop across the resistor to determine the logic level The current level swings in the wire are about 3ma with a voltage differential of around 350mv This allows for transmission of the video signal with minimal EMI The LVDS receiver on the TCON board converts the serialized data back to parallel.

Distribution substation A distribution substation transfers power from the transmission system to the distribution system of an area The input for a distribution substation is typically at least two transmission or subtransmission lines Distribution voltages are typically medium voltage, between 24 and 33 kV depending on the size of the area served and the practices of the local utility. A feedback voltage obtained from voltage divider R 1 and R 2 is applied to the opamp’s noninverting input and compared to the Zener voltage to control the drive current to the transistor The current through resistor R S is thus controlled to drop a voltage across R S so that the output voltage is maintained. 5 index ABB Low Voltage Contractor 0312 1 ABB is a founder member of Voltimum which was launched in 03 Voltimum is an internet portal for the electrical industry and is active in 6 countries within Europe.
