About Fake Transistor
I have an ERG member who told me that he may have bought a fake transistor. Before that the monitor that he repaired have power and high voltage but after the replacement with the new HOT, now the monitor have no high voltage. Even putting the original HOT back does not make any difference and he found that the new HOT was shorted between the C,E pin. He replaced the HOT because he suspected that the HOT was the cause of the display problem (after knocking on the HOT, the display with shadow will be gone). So he compared the HOTs and and found some differences especially the top part that was not smooth. You may see the picture below.
Actually many years back i came across a fake HOT with the number of BU2508DF. It works only on some monitors and not all monitors. I have confirmed it in few different working monitor. When i place the fake transistor on a working Monitor, the monitor start to power blink. Putting back the original HOT, the Monitor came back to life. If you have came across such situation i would like to hear from you.
