HOT transistor is continuously getting shorted after replacement



For those who have been in repair business for a while you will agree with me that this is a common phenomenon.

You receive a TV in your shop and you diagnose the problem and found the HOT is shorted and you begin to celebrate how you got the culprit effortlessly.

You pull a new HOT transistor and replaced it and powering on the TV came up beautifully and before picking the phone to call the owner to collect his machine you realized that the TV is down again.

You check again and find the HOT is shorted again. If you have never experienced such a problem lucky you, but for Abdul Haleem from Sri Lanka has not been lucky... Lets us hear his story.
