CIRCUIT DESCRIPTION POWER SUPPLY OPERATION EXPLANATION POWER ON AND OFF The power supply in the ZP94 & 95 chassis works very similar to the previous models, with only a few exceptions. This power supply runs all the time when the AC is applied. The use of the power supply creating Standby Voltage supplies eliminates the need for a Standby transformer. The following explanation will describe the Turning ON and OFF of the projection television.
CIRCUIT DESCRIPTION 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 SW+12V and SW+5V regulator. Which are turned off in Stand By. POWER SUPPLY FREQUENCY OF OPERATION DURING RUN: When the Horizontal deflection is in operation, the power supply frequency fluctuates in accordance to screen brightness, causing differing demands for High Voltage replacement.
CIRCUIT DESCRIPTION HIGH VOLTAGE DRIVE CIRCUIT: When QN04 is turned on, the 11V standby will also be applied to the High Voltage Drive IC IH02 pin 14 via RN15 and DN13. When this occurs, the IC will stop generating the drive signal that is used to produce High Voltage via QH08, the High Voltage Driver. Again, this is done to prevent CRT burn, especially during sweep loss. GREEN LED: The Deflection B+ 120V supply is generated from pin (13) of TP91. This output is rectified by DP11 and filtered by CP17.
CIRCUIT DESCRIPTION connected to the negative SW-8V line and RP25 (3.3K ohm) is connected to the positive SW+8V line. The Cathode of DP28 monitors the neutral point where these two resistors are connected. If the negative voltage disappears, the zener DP28 fires. This high is routed through DP29 to the gate of the Shut Down SCR QP01 and Shut Down occurs. EXCESSIVE CURRENT DETECTION: 9.
CIRCUIT DESCRIPTION SPOT PROTECT or SPOT KILLER: As mentioned earlier, when the deflection power supply goes into shutdown for whatever reason, a low potential will be applied at the cathode of DN14, forward biasing it and causing current flow through RN07. Once again, this increase of current flow through RN07 will bias on QN04 and the events described previously will occur. SWEEP LOSS DETECTION: The key component in the Sweep Loss Detection circuit is QN04. This transistor is normally biased off.
CIRCUIT DESCRIPTION DAC1 I003 and DAC2 I004: These Digital to Analog converter acts as an extensions of the Microprocessor( Sometimes called an Expansion ICs). The purpose of these ICs are to reduce the number of pins, (fan out) of the Main Microprocessor I001. The Main Microprocessor send Clock and Data via I2C bus to the DAC1 IC. The output from the Microprocessor is pin (2 SDA1 and 3 SCL1) which arrives at the DAC1 and DAC2 ICs at pins (5 and 6) respectively.
