This power supply runs all the time when the AC is applied. The use of the power supply creating the A12V supply eliminates the need for a Stand-By transformer. The following explanation will describe the Turning ON and OFF of the projection television. he Microprocessor generates the ON-OFF control signal as before, with the exception that there is no Relay Driver. The schematic shows a relay driver Q003, however it is in parentheses. This means that the component doesn’t exist in the set. This On/Off control will perform the following : • Turns on the regulation control signal • Turns on the A5V and A9V regulator • Turns on the Shut Down “Power Shorted” detection circuit • Turns on the Horizontal Vcc supply to the Rainforest IC, I501 The Microprocessor outputs the On/Off control from Pin 35, to the PSD3 connector Pin 4. (See Figure 1) The active state is On = High and Off = Low. The high for Power On is then routed to Q908 and Q907. Q908 is turned On, removing the base bias for Q907. Q907 turns off and removes D948 from the circuit of Pin 2 of I905 which is the regulation error voltage feedback line for the regulator IC, I901.

However, due to another factor, this doesn’t cause the power supply frequency to rise to maximum which will be described next. HORIZONTAL B+ DEFEAT CIRCUIT: (See Figure 2) hen the power supply goes into Stand-By mode, the Horizontal Drive signal for deflection is shut off. This is accomplished by Q916 and Q917. The Low out produced from the Power On/Off pin 35 of the Microprocessor is detected by the base of Q916. This allows the collector voltage to go high. This action turns off Q917 which removes the B+ from its collector. The Collector of Q917 is connected to the Deflection B+ pin 22 of the Rainforest IC, I501 via pin 3 of the PSD2 connector and Pin 13 of the PSI1 connector. This action stop I501 from producing a horizontal deflection drive signal.

This low current demand is detected by the three resistors connected to the source of the internal Switch MOS FET inside I901 via pin 2. Pin 4 of I901 is the over current detection pin, however it is also the current demand sensing pin. When the current demand is low due to horizontal defeat, pin 4 will be less that 1.4V and the internal frequency will switch to 20Khz. This is caused by the Quasi Resonant circuit operation which is covered in a Hi-Lite article. This reduction of power supply frequency will move the frequency below the Bell of the power supply transformer and all secondary voltages will reduce to approximately 1/2 of their normal voltage. Due to the fact that the power supply is still operating at 1/2 voltage output, the Green LEDs used for visual trouble sensing will reduce in intensity, however they will remain lit. With the exception of the TV9V and TV5V regulator. Which are turned off in Stand By. W (Continued on page 3) Deflection B+ 60V 1 Power Supply Driver & Output IC Cold Gnd.

This is because of the wide range of input voltages from Stand-By to Normal operation of the Power Supply. The TV9V regulator (I912) and the TV5V regulator (I913) are shut off during Stand-By mode. This is accomplished by Q906 and Q905. When the low for the power On/Off pin 35 of the Microprocessor is detected by Q906, it’s collector will go high. This action will turn ON Q905 and its collector will go low. This will pull pin 5 of I912 and I913 low, turning off the two DC to DC converters.

This could cause a potential problem with the Short Detection circuits for shutdown. To avoid accidental shut down, Q906 also controls the activity of Q905. During Stand-By, Q906 is turned off. This allows the Base of Q905 to be pulled up which turns on Q905 and its collector voltage is low. Q918 is also turned off because its base voltage is pulled low through D975. This prevents any pull-up voltage from appearing on the emitter of Q913. The base of Q913 is connected to 6 Low Detection inputs, (See AP93 Power Supply Shut Down Circuit). When the power supply operates at 50%, the Short Detection circuit could activate. By turning off Q913, no accidental shut down operation can occur. For added protection, Q912 also prevents any Shut-Down voltage from reaching the Gate of Q914, which is the Shut-Down SCR latch.
