This appears to be a South African unit? See if the link works better for you. An electronics technician could fix by component testing and by knowing how to wire a transformer (high voltage windings and low voltage windings).
If a company has the facility to wind their own transformers, they will probably find it possible to wind to their exclusive or special specification while saving cost but when production ceases it can be difficult to replace from a generic catalogue - but if the transformer was a bought-in component the chances are good there will be a catalogue of generic transformers, one or more of which will meet the required specification.
In the case of a special specification it might be necessary to fit more than one generic transformer to perform the function of the original. I have seen several machines and appliances where an enterprising engineer has faced that problem and had overcome it by fitting two or three transformers in place of the original.
All you need is the specification and that should be provided by the service literature, a service engineer or by very nicely asking the company...

they are modules that don't require power to run, aside from the power source the circuit is connected to. These modules don't generate or hold power but they are able to amplify power, a transformer is an example of a passive circuit component.
The most likely cause is a component failure in the power circuit. This can be repaired fairly inexpensively. However, it's not really a user serviceable problem and should be looked at by a qualified technician. Here is a link to a repair shop that should be able to help you.
There is no "Flyback transformer" in the LCD monitor "Benq 17" model No. Q7T3". Such a component, a "Flyback transformer" is found in televisions and in Picture Tube type monitors. The red wire of a "Flyback transformer" is where 27,000 VOLTS comes out of to connect to the picture and such a voltage IS DEADLY so never enter a TV or computer monitor unless you know exactly what you're doing. To bring your hand too close to the "Flyback transformer" is to GET ZAPPED, you don't even have to TOUCH that transformer or the Red Wire that comes out of it!!!!
As far as a fuse blowing, NEVER PUT IN A FUSE WITH A HIGHER AMPERAGE RATING: it's there to protect certain components from being permanently damaged. If the fuse is blowing you must find out "why". There's got to be a short circuit in one or more components. Transistors, Diodes and Capacitors are easy to check for shorts. Transistors, Diodes are usually what short out. There's not much more I can say here.
A schematic diagram that shows the voltage on the many components of a running LCD circuit is what you need to find out where volatges should be. If a voltage is missing you must find out where the problem stems from. There are other ways to test circuitry, with an oscillascope and a schematic diagram that shows test points and the wave pattern that's suppose to be present.
Here are trans transformer and electric transformer (small model is mainly for overseas travel). There is no problem when using trans transformer, however when using electric transformer, there are many models which cannot be used with battery charger, precision instruments and so on.
