transistors are high voltage transistors with a higher specification than normal transistors. It is generally in the range of the power transformer as power transformer and flyback transformer. On television and monitoring the high voltage flyback converter used to generate a high voltage transistor is required to perform the work. And 'flyback transformer adjacent to the site in detail and attach to a heat sink to transfer heat quickly. This canShock in a very short time thanks to the hard work of the transistor in the exchange. number of typical piece of high voltage transistor that is used in TV and Monitor BU2508DF, C3998, C5148, C5047, C5589, C5803, etc. and usually is your assessment of volts, amps and watts in 1500 volts and above, 10 amps, 50 watts, and more. Their dimensions are much larger than the transistor common signal. If the transistor is short-circuited high-voltage, you have to find the exact number of spare parts for equipmenttake longer. spare part number does not take long, perhaps in a few weeks or months, and will explode again, if you know the storage and reduction over time of the transistor.
Higher voltage, amps and watts do not guarantee that your transistors will be long. Many times a fraction larger than a specific claim is in shock when you switch on. You must go to the respective manufacturer's data sheet and get transistors, Spectransistor. Before the fall time and the time value of storage. The original and the replacement value should have a tolerance of not more than 20%. If the replacement transistor to run hot and eventually blow the transistor. This is your time.As valuable because sometimes even the next transistor specification does not work too well because the waste is special in devices such as monitor-coil and the yoke of the flyback according to specifications designedTransistors.
Thus, only the original number of transistors that will be installed in that special equipment can. I also saw the initial number of different lots of the transistor, when installing the monitor, which displays the curve (outside pincushion) and the transistor is very hot. I have all the cables and components that are tested, with the transistor to be in place. Even the replacement of the flyback transformer help either. The transistor temperature continues to rise and if ITurn off your monitor, so I think it will eventually blow the transistor. I took the transistor and compared with the original logo and found that the replacement is a bit 'different from the original transistor-logo. When I called my supplier of electronics for the logo, said it is the transistor that I bought a newer version available, just the same factory. After a long time to find the original transistor, I managed to find one. Incredibly, the originalTransistor is replaced, which are cool and the picture is perfectly fine. Guess what is the high voltage transistor part number? It 'was C5148!
In another case, there was a monitor came with no power symptom. After careful consideration of high-voltage area, has confirmed to me that this name is short circuit caused no power. After the exchange (the part number was BU2508DF) when the monitor is turned on, the power of flash. I thought there are some other components because the evil power of flash. IRecheck the power and high voltage section, but could not find the error. I got hot that I just replaced and realize that it was a bit 'different than the original. I took another hot is exactly the same compartment of my shares, and voila, the monitor works perfectly well. I'm beginning to warm and can be seen clearly by comparing themselves from the picture below.
The lesson I learned from this mistake, always with a spareOriginal part number (if possible) and do not buy all the components that is cheaper than the normal market price.
