Digital Cameras: Hot Gear with the Coolest Features!

Written by The eme team


Cameras: still known for taking pictures but assumed as digital still today.

We have to understand cameras are just as important today as they have always been to us. Most photographers thought whenrepparttar digital age began; we would be taking fewer pictures because there would not berepparttar 151139 wasted photos we didnít want.

Digital cameras today have not only done this but surprisingly increased our photography enormously!

It should have been expected with allrepparttar 151140 electronics technology, picture taking would increase, not decrease. Yet many of us made an incorrect assumption. Since we know we can take pictures and edit them instantly on our camera, we continue shooting more photos without that fear.

Terms like mega pixel, optical zoom, LCD size, movie mode all have been adopted easily and quickly in our rush to get a digital still camera. Today, fearlessly, we can easily pick higher mega pixels, a larger LCD size, more or less optical zoom and shoot a movie mode sometimes never before tried.

Have you ever come across power problem where once you switch onrepparttar power supply andrepparttar 151002 fuse blow? You have checked allrepparttar 151003 components inrepparttar 151004 power (primary) and secondary section and allrepparttar 151005 components seems to be ok! Where isrepparttar 151006 fault? A fuse blown are usually caused by a shorted bridge rectifier, defective posistor, power transistor or FET, shorted primary winding of switch mode power tranformer, shorted secondary diode and etc. But in this article i'm gone to show you another secret of electronic troubleshooting tips.

I got frustrated as to where isrepparttar 151007 cause of power problem. Everytime when i switch onrepparttar 151008 power supplyrepparttar 151009 fuse blow immediately (the fuse became dark color and this indicate that there is a major short circuit inrepparttar 151010 power supply). I have checked allrepparttar 151011 components inrepparttar 151012 power supply and can't findrepparttar 151013 culprit! What i do is i desoldered allrepparttar 151014 suspected parts one by one and replaced with a known good component. I eventually foundrepparttar 151015 caused ofrepparttar 151016 power supply problem. Guess what? It wasrepparttar 151017 main filter capacitor (220 microfarad 400 volt). After replacingrepparttar 151018 filter caprepparttar 151019 power supply worked perfectly fine. I begin my detective work to find out why this capacitor can causedrepparttar 151020 fuse to blow eventhough i already confirmed it ok with my meters.

The meters that i used to checkrepparttar 151021 filter cap were analog meter, digital capacitance meter and esr meter. In this article i will not explain about how to check capacitor or testing capacitor and how capacitor work. I believed most of you know how to check capacitors and also generally using this type of meters. Measured with analog it showed capacitor charging and discharge, with digital capacitor tester it showed around 220 microfarad and with esr meter it showed low esr reading!
