How to repair electronic ballast, how to detect the broken one
Electronic rectifier usually does not repair because the price is lower. And the repair shop is also unmatched electronics. If it's a CFL, just buy the same number of watts. You don't need to be exactly the same.
The most common failure of electronic ballast is: Switch tube damage, damage of resonant capacitance, filter capacitance is damaged, as long as open the electronic ballast, the multimeter to check more than the original, it is not difficult to find out the fault components, can be used after change new.
The electronic ballast of energy-saving lamp fluorescent lamp USES more in the place of frequent switch USES the error rate is higher. Now, the price of the rectifier is very low and there is no maintenance value, because the original damage is the same, so there is no need for the original repair. If there is a multimeter and accessories based maintenance is simple, and has certain triode and string is usually a long bad capacitance on the lamp, electricity no reaction is more commonly breakdown short circuit or short circuit, burnt triode can make level protection resistance before burning at the same time, it is best to use table can be easily measured triode remove the measurement. If the electric start slowly or triode normal cannot start is spoiled or capacitance of explosion pulp damage more, mainly small capacitance in series between tubes and several other electrolytic capacitor, the capacitance of doubt removed the multimeter capacitance detection.
