LOPT - FLYBACK EHT TRANSFORMER COMPARATION TABLE ORIGINAL ---> HR DIEMEN SPARE PART LIST 6

Here below a code list of the original Flybacks LOPTS of many CRT TVs. These DC flybacks are found in every CRT computer monitor and are called the DST flybacks (diode-split transformers) because of the several high voltage diodes and secondaries inside. In addition to the high resistance resistor cascade (Bleeder) and focus/screen tuning potentiometers described above, these kinds may have an integrated high voltage filtering capacitor (few nanofarads at >=30 kV), or – optionally – a HV capacitor for dynamic focus.

The TV  DC flybacks are also diode-split (DST), however these are found in every modern CRT TV-set from mid-end 80s and onwards. These have just two screen-tuning potentiometers and no internal capacitors whatsoever !

 Comparison list is organized with original code to the HR DIEMEN correspondent Replacement part.

Line transformers generate the necessary deflection pulse and other many key voltages and the  high voltage for anode of the picture tube in tube televisions and computer monitors. Usually this is around 30 kV for a color device, but the current is  with approx. 0.5 to 4 mA.

The line transformer or horizontal output transformer (English: flyback transformer or line output transformer) is part of a television / monitor with picture tube. It is used to supply the line deflection coil of the deflection system and at the same time usually also to generate the high voltage of 20 to 30 kV required for the operation of the picture tube and other voltages necessary for the operation of the device.

Line transformers work with the line frequency, with European TV sets with 15.625 kHz. Line transformers of 100 Hz televisions work at twice the frequency, i.e. at 31.25 kHz. In monitors, the line transformer is operated at different frequencies, which depend on the resolution of the image sent by the computer. For example, the line frequency of a monitor with a resolution of 1024 × 768 pixels and 85 Hz vertical frequency is approximately 68.7 kHz. With these frequencies, the line output stage switches a switching tube or today a switching transistor, which are used to control the line transformer.
The whistling noise of some older monitors and most older, conventional TV sets arises from the fact that mainly the line transformer, but also other components such as coils and capacitors, are mechanically excited to vibrate by the occurring magnetic and electrostatic forces. Whistling has a frequency of 15.625 kHz due to the European television standard. TVs with 100 Hz technology and most high-resolution computer monitors whistle outside the listening area........

Line transformers are potted with resin and have a ferrite core and are therefore of course only suitable for high frequencies in the kHz range. Newer types, so-called diode split transformers, contain many individual diodes between the windings and thus supply a rectified high voltage (pulsating DC voltage). Older models made of black and white devices have an external cascade, the direct (high-frequency) output voltage is then only about 8 kV, but a little more current is available with such AC line transformers. Line transformers require an electronic control circuit which provides a square wave signal in the range of approx. 15 kHz.

Diode split transformer with permanently cast diodes and DC output The advantage of line transformers: They are easy and inexpensive (or free) and can be obtained in large numbers at radio / TV shops and in computer shops where devices are disposed of. Especially nowadays, in which tube monitors have to make room for flat screens, many old monitors and TVs are disposed of.

Removal and wiring of a line transformer:

Important when removing the line transformer from the TV or monitor: First discharge the picture tube, then remove the high-voltage connection, and draw out the pin assignment of the line transformer before unsoldering. Two connections are particularly important: supply supply (approx. 150V from the power supply unit) and connection that goes to the collector of the horizontal output transistor or on very older types to a tube or thyristor final stage.


The thick, well-insulated, red cable is the high-voltage output (approx. 30kV), while the somewhat thinner, black cable carries the focus voltage, which is only around 6kV. Finally, the orange cable brings the grid 2 voltage, which is only a few hundred volts. Television and monitor flyback transformer pinout have some common designed except that the monitor flyback have a internal capacitor built in. The internal capacitor value have around 2.7 nanofarad to 4.5 nanofarad to improve the picture quality especially when the monitor which can go for a higher resolution compare to Tv. If without the internal capacitor in the monitor flyback the display will curve or slightly out of shape especially at both the right and left hand side of the picture and may present other imperfections not admitted for monitors. It acts as a filter. Internally they may have a high vealue resitor (600 to 900 mega ohm) in parallel to HV output. This to adapt the ouput impedance of the LOPT to the CRT Anode.

Mostly tv and monitor flyback transformers have about ten pins at the bottom of the flyback. Each of the pin have a purpose or function as part of a complete circuit. The common pins that you can find in monitor flyback are: B+ pin, Horizontal collector pulse, ABL (automatic blanking limiter), GROUND, G1, AFC (automatic frequency control), VCC, HEATER (to filament) and X-RAY protection.

The B+ and horizontal collector pulse pin forms one winding which we call it as flyback primary winding. It can  only can be test by using a flyback meter such as the  Lopt tester flyback transformer pinoutor sencore LC102 and LC103C.

Note that some monitors and TV design may have a separate HV and deflections circuits
.
Normal meters can't check this kind of fault. This is the most important winding compares to others and it can easily developed a short circuit when B+ voltage line or Horizontal output transistor (HOT) shorted. Sometimes a shorted internal capacitor in the flyback transformer may cause the primary winding to burn internally and the flyback became bulge and poured out the epoxy.

Other pins are the ground, G1, and AFC winding. AFC stand for automatic frequency control and it send signal (pulse) from the flyback transformer to the horizontal oscillator ic to lock or synchronize the frequency of the monitor. If this AFC line fails the picture will shift either to the far left or far right. There is no way that you can adjust the picture to the center even with the internal adjustment in the mainboard. The purpose of G1 voltage is to pull the electron generated from the cathode (after the heater or filament heat up) and passed it to G2 which is the screen voltage.

G1 normally is a negative voltage or positive from few volts to 32 volts in some most ancient designs . Most tv picture tube do not use G1 voltage. If the G1 voltage is missing or zero voltage to the picture tube the monitor display will becomes very bright with retrace lines (diagonal lines or flyback lines) across the screen and sometimes the monitor will goes into shutdown mode.
ABL stand for automatic beam limiter- I refer it as a limiter further circuit. Why? because whenever there is a contrast or bright problem i will search for this pin and begin to trace from there. Normally a resistor increased in resistance and a shorted ceramic capacitor caused the display to become dim and you may think it might be the fault of a bad CRT.

Heater or filament pin nowadays hardly found in monitor flyback because the crt heater voltage now is derived directly from the switch mode power supply. However heater pin is still can be found in television flyback transformer. If the anode voltage is too high (more than 30 kilovolt), the x-ray protect pin will send a signal to horizontal oscillator ic in order to disable the horizontal drive waveform THIS FOR SAFETY REASONS.

Without the horizontal drive pulse the high voltage generated by the flyback will collapsed and protect the user from excessive x-ray.

The flyback transformer pinout will also generate high pulse ac which later convert to dc through an ultra fast recovery diode. For your information, the ac pulse generated by the flyback transformer cannot be check with our normal analog or digital meter. the frequency is so high and you need a special meter to do the job. The dc voltages are then supply to various circuit such as the vertical output circuit. If you  understand all the functions of each flyback transformer pinout, repairing  monitor or tv will be much easier and save your precious time.
