LOPT - FLYBACK EHT TRANSFORMER COMPARATION TABLE ORIGINAL ---> HR DIEMEN SPARE PART LIST 19

LOPT - FLYBACK EHT TRANSFORMER COMPARATION TABLE ORIGINAL ---> HR DIEMEN SPARE PART LIST 19

Here below a 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 corresponding 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.
