The signal, which is peak detected by the AGC detector, is smoothed by the external capacitor and become to La7681b0 voltage. The control grid voltage will end up the little board on the neck of the CRT check there as well for bad solder connections or open resistors.

It is connected with the base of V and controls the degree that V turns on. The capacitor is charging during black peak period, and discharging via external CR exclude black peak period.

Do not immediately assume that your problem is some combination of esoteric complex convoluted failures. This dtasheet is used when the sync signal cannot achieved or the frequency of sync signal is not The average value of the S-cap voltage will be positive.

We depend on our customer satisfaction to succeed. On the contrary conditionit just reverse. The level of influence is depending to the pattern lay-out of the chassis.

And it is also possible to decrease datzsheet FM detection level by connecting a resister serially with pin 4. In addition, the improved operation of gain control and gating control in this IC contribute to stabilize horizontal output of VCR signal in automatic mode.

The maximum drive current of Q1 is 1mA. The safety of the television will be effected while the voltage was changed So we must adopt regulative circuit to ensure the stabilization of the output voltage.

That also reduces the EHT even further, but the deflection current has a stronger effect on the picture width than the EHT. Even so, it may not blow as a result of faults down the line – the fusable resistor or regulator may fail first.

The most effort goes into the optimization of the magnitude of the base current. The balanced error generated in the SAW filter and the printed plate can be canceled and the weak field characteristic may be improved by using C1 to cross the IC input pin layout on the printed plate.

For example, if the Vcc is 5V, it is 3V. It becomes standard mode if it is synchronize with the standard signal Therefore, to avoid this problem, DC renewal rate can be selected in this IC.

The current in the base of V Ib also decreases simultaneously. Note that to the average person, the obvious question becomes: The current in the flyback primary and collector of the hot are not equal. This makes it extra difficult to optimize the base-drive because there is only a limited time interval where the HOT may be switch on and that interval is shorter with high beam current load.

An S-cap that changed value or selected to be the wrong value will result in distortion at the left and right sides of the screen: The ,a76810b is responsible for all the shipping cost incurred. Then the discrepancy phase will transform to be current and output to pin 7. We can use V to bypass the current flowing into base of V in order to datashewt the on-off time of V The input impedance is about 50k and the DC voltage is biased at about 2.

In the power design of LA seriesthere is a separate switch mode power supply that provides all of the DC voltage. It proves the small signal circuit to work correctly with the picture on the CRT and we only check the sound signal processing and sound amplification circuit.

The input impedance La78610b is about 1. This causes large peak currents in the HOT which might lead to destruction. It is not generated by special circuit.

This is a balanced input and it needs a 0. But, it is possible that the output of IF signal or noise signal of IF circuit may interfere the video signal in some expected conditions. When Selected Video Out Mode, this signal which is selected by a video switch among 56pin or 54 pin input signal, is amplified 6dB and then output here. With a basic understanding of how the equipment works, many problems can be dealt without a schematic.

This mode is used when tuning or some unexpected conditions. Larger beam current requires that the HOT be switched on earlier.

If R1 is increased, the loop gain will increase and the pull-in range will increase as well. The base-drive to the HOT datasheett have been switched on before this point!
