Checking the output voltage from the power adapter I got about 19 volts that is very good. I once came across a Compaq 17″ LCD Monitor which have a precise output voltage from the power adapter but when connected towards the Monitor, the show appeared to get a fraction of a second just before shutting down. Usually after power off, I would touch on the flyback first then to other components surrounding the high voltage section.

In the event the LCD Monitor issues falls in the 1st and the second categories then replacing only the fuse will unquestionably resolve the issue. Slowly vary the output voltage and monitor the existing drawn.

The ac provide was plugged in to the power adapter and 701e could see the energy LED was lighted up. Navigation Home Recent changes Random page Help. Please take note for all electronic repairers-switch off and unplug the power cable and discharge the big filter capacitor in primary side before you begin to touch any components.

A defective power IC, lh fet breakdown when under load, high esr in electrolytic capacitor, increased in current sense resistor value, a shorted zener diode, a leaky transistor, open circuit or resistor has changed value in primary side ly cause power to blink.

A power blink problem can be cause by either in primary or secondary section or even in both sections.

Initially it is possible to use an external regulated energy supply as explained in my preceding repair articles and connect the adverse output of your energy supply to ground and also the good towards the fuse the line that leads to other circuitry as a way to detect the short circuit. George rapidly assured her that with temperatures reaching degrees that 170e, coupled with her jet lag that she was just tired and necessary to visit bed.

After they arrived residence from the airport at eleven in the evening, Elle noticed that the house seemed a bit as well warm for so late within the day.

You may have only two selections to solve this sort of problem. Now where is the culprit hiding? While browsing the components with my finger I stumbled upon a resin coated ceramic disc capacitor which is quite hot.

Retrieved from ” http: Elle and George had just returned from ten relaxing, sunny and breezy days within the Caribbean with their kids only to seek out that they had come house to a steamy house. A good capacitor should show a charge and discharge activity in the X10 k ohms range. Once the present drawn about a amp or two, now place your finger to any electronic components within the primary board. Troubleshooting sometimes can be very frustrated and most of the time is always fun.

710r the cap was removed and checked with an analog meter, it showed a shorted reading even in the X1 ohms range. So, immediately after a handful of telephone calls George found a place that would sell him a capacitor directly. Even so, for this LCD Monitor, replacing only the fuse did not perform at all plus the fuse open circuit again.

One of my methods that I liked to use is to touch for any unusually hot components on board with my finger.
