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.

Just after researching a little on-line George discovered that the piece he was looking at was the capacitor.
This page was last modified on 24 Augustat So, immediately after a handful of telephone calls George found a place that would sell him a capacitor directly.
Even though the LED has lit and correct output voltage, this does not imply that the energy adapter can retain when there is a load the LCD Monitor connected to it. But, definitely George knew that an AC repair was imminent, but all he could contemplate was going to sleep just after pg long day of traveling. One of my methods that I liked to use is to touch for any unusually hot components on board with my finger.
The ac provide was 710s in to the power adapter and I could see the energy LED was lighted up. A power blink problem can be cause by either in primary or secondary section or even in both sections.
Even so, for this LCD Monitor, replacing only the fuse did not perform at all plus the fuse open circuit again.

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. Troubleshooting sometimes can be very frustrated and most of the time is always fun. It is located near the flyback transformer and in fact the capacitor was 7710e is to act as a filter capacitor 710f the vdc line output as shown from the photo. But, just after sleeping in until 11 am inside the morning Elle woke to discover that the home was chilled and comfortable.
While browsing the components with my finger I stumbled upon a resin coated ceramic disc capacitor which is quite hot. Now where is the culprit hiding?
Checking the output voltage from the power adapter I got about 19 volts that is very good. You’d be surprised that the actual lead to on the shutdown was as a result of the energy adapter. And surmised that using the intense temperatures his air conditioning was frequently running even set at 80 degrees along with the capacitor had burned out because of it.
Small did she realize that her husband got up really early inside the morning to diagnose and fix the issue just before any individual could feel the heat. It cannot sustain the output voltage when there’s a load on it. When you located any elements that get quite hot then which is the bring about of the quick circuit.
Ordinarily within this case, your skilled would inform you that it may be the inverter circuit are faulty or the lamps have dilemma. A good capacitor should show a charge and discharge activity in the X10 k ohms range. 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.

George rapidly assured her that with temperatures reaching degrees that day, coupled with her jet lag that she was just tired and necessary to visit bed. Plasma TV Repair Ebook. Usually after power off, I would touch on the flyback first then to 710r components surrounding the high voltage section.
Once the present drawn about ,g amp or two, now place your finger to any electronic components within the primary board.
