MONITOR LCD BENQ FP731 POWER PROBLEM

In the case of brand monitor BENQ, I took a sample of the type: LCD BENQ FP731.Seperti most damage happened on the monitor type LCD is the case of failure of power system supply.Apalagi on this model, the block is very neat and compact regulator is integrated in a pack / case aluminum distinguished meeting, so that free air exchange becomes difficult.Immediately, on intinya.Jika you get this type lcd monitor has a problem can not be distinguished in turn, soon you dismantle all tutp casing from the rear, and lift all the aluminum cover to block power supply.Maka will look like below.

It appears the regulators block, then you can instantly tell what components are visible damage, but wait a minute, get used to examine several components of the major regulators in this block, especially the first time you check the fuse / fusenya, if broken immediately check the main transtor . In the case this time fuse and measured its IC core is good, then switch on the secondary tracking regulators, check the start of the secondary diode first, after that you can immediately replace some that look elco menggembung.Meskipun leak and you simply replace some of the visible elco Physical has leaked, but there is also a good idea to replace at the same time several other supporting elco, with reasons for working this regulator can work normally again without the risk back into your lap.

In the picture below, which damaged most valuable elco 470/16/25 and 1000/16-25V.Persis with damage that occurs in some other brand of LCD monitors.BENQ LCD monitor repair is apparently not as difficult as what I had expected this sebelumnya.Pengalaman may be useful for you, and at least some mental support for the other electronic hobiist.I say a big thanks to mr.Jestine Yong (Malaysia) who volunteered to help me in deep engineering and troubleshooting tricks in the LCD.
