The Damages On Flyback

Previously I would like to explain the difference flyback is on TVs and monitors internal capacitor. FBT Monitor has an internal capacitor to improve the quality of the picture. Without internal capacitor looks will look crooked or deformed shape, especially on the Left and Right Image. The Damages On Flyback

Here’s Damage – Damage In Flyback:

There are nine problems commonly found in the FBT problem:

1. Primary short-circuit or coil Short
2. Open or Short in the internal capacitor in secondary section FBT
3. FBT becomes swollen or nearly broken, or even broken
4. Outside FBT splash or the sparks emission (leak) into the Ground
5. In spark or emitting part (leak) between the primary and secondary winding
6. Short in High Voltage Diodes bag in the secondary coil
7. Damage to the Focus Voltage Divider / Screen Display which resulted in a Blurred (Blur)
8. FBT was damaged when the full operating voltage (Under load condition)
9. Short in between the primary and secondary winding

What are the symptoms or signs that appear in the event of short primary winding?

* No Display (No High Voltage)
* Power Blink
* B + voltage drop
* Horz output transistors will be very hot and over time becomes short
* Disekiotar Line B + some components will be damaged, such as the secondary diode and FET B + UF5404 IRF 630, short.
* Sometimes the cause of Power to be broken.

What are the symptoms or signs are visible case of internal capacitor in the Open or short in the FBT?. The Damages On Flyback

If Internal Capasitor Short:

* Power Blink
* B + voltage drop
* Horz output transistors will be very hot and over time becomes short
* Around the Track B + some components will be damaged, such as in secondary UF5404 diode and FET B + IRF 630, short.
* Sometimes the cause of Power to be broken. Example 15 Raffles Brands’
* The Power has shut down, as examples of Brand Compaq V55, SAMTRON 4bi, etc.
* Sometimes the components in Section ABL (Automatic Brightness Limiter) on fire, this section is usually found next to the FBT, Brand LG 520 Si samples.

If the Internal Capasitor Open:

* High Voltage shutdown
* Monitor will sound Tik-Tik-Tik, Sometimes If we measure the results capacitor Both fine, but will experience a breakdown when the operating conditions of Full Voltage
* Transistor output will be broken Horz / End in a few hours or days after you replace it.
* Sometimes, sometimes causing the display “No display”
* Images are distorted
* Can cause Horz output transistors short and damage the Power


You have three options if an Internal capacitors on FBT has open or short:

* Replace with a new FBT if you get it on the market
* Trying to find FBT refurbish If it is very difficult to get original parts.
* Perform modification or terms of practitioners is the transplanting technique
* The final choice to the consumers Return Monitor If you can not find a comparison of the FBT. The Damages On Flyback
