Why is horizontal output transistor in CRT monitor get shorted?
Why is horizontal output transistor in CRT monitor get shorted?
There are many reasons why the horizontal output transistor (HOT) shorted in CRT Monitor. Here are the possible cause: HOT have life span-it can work for many years but out of a sudden it can just go shorted.
When to replace parallel transistors in an amplifier?
In the case of the output transistors, if you find only 1 shorted in a group of parallel-connected transistors, you can reinstall the ones that are not shorted to see if the amp will power up. If it does, you need to replace all in that group of parallel transistors.
Can a power supply short in an audio transistor?
This is generally only viable for audio output transistors. Generally, when one power supply FET shorts, all will fail and all will have to be replaced. Notes: Above, it was stated that you shouldn’t read anything near 0 ohms between the legs of any individual transistor.
When do you need to replace a power supply transistor?
This is generally only viable for audio output transistors. Generally, when one power supply FET shorts, all will fail and all will have to be replaced. Notes: Above, it was stated that you shouldn’t read anything near 0 ohms between the legs of any individual transistor. This is the case for MOST transistors.
