☑ Horizontal Output Transistor Troubleshooting

Hot transistor is not valid as an amplifier but accepted as a on off switch pulses driven. 1071 hot horizontal output transistor serves to provide sufficient power to be able to generate voltage pulses to horizontal deflection.

Notes on the troubleshooting and repair of television sets.

Horizontal output transistor troubleshooting. Horizontal output transistor problems free download as pdf file pdf text file txt or read online for free. If you find one then test the hot andor switchmode transistor for shorts. Troubleshooting horizontal failures if the monitor has a blown fuse chances are excellent that the horizontal output transistor has shorted.

There are many reasons why the horizontal output transistor hot shorted in crt monitor. Hot transistor generally get suply voltage b of about 100 to 150v dc. By the horizontal output transistor.

Basically when testing the hot first bear in mind all hot transistors has b c e 123 leg distribution and therefore testing between c and e in circuit expect high and low. How to prevent the horizontal output transistor hot from getting shorted after replacement 34 how to bypass lcd tv inverter board shutdown backlight system 20 how to repair toshiba m200 series laptop with no display problem 12 lg 42pc5dc plasma tv switch mode power supply operation and troubleshooting 10. Pls sir how can i test horizontal output transistor in circuit and out of circuit so as to know bad one.

Hot transistor is not valid as an amplifier but accepted as a on off switch pulses driven. It provides a path for current to flow through the flybacks primary winding and horizontal yoke as shown in figure 2. Replacing only the hot solved the probem.

Here are the possible cause. Simplified horizontal output stage. A failure of the horizontal output transistor or power supply switchmode transistor will blow a fuse or fusable resistor.

Hot have life span it can work for many years but out of a sudden it can just go shorted. The hot is switched on and off by a signal applied to the base. Plays in the operation of the output stage.

Remove the power to the monitor. Hi kutelu kindly read your ebook page 5253 for more info on this. 1071 hot horizontal output transistor serves to provide sufficient power to be able to generate voltage pulses to horizontal deflectionhot transistor generally get suply voltage b of about 100 to 150v dc.

Scribd is the worlds largest social reading and publishing site. You can check it with your digital multimeter. Set the meter to the diode test setting.

If your meter does not have a diode test use a low resistance scale. Output transistor the horizontal output transistor hot is a switch. Look for blown fuses and test for open fusable resistors in the power circuits.
