Power Supply Capacitor
Utilize A Multimeter To Location At The Secondary Aspect With Power On
The DELL E151FP LCD Keep track of came in with no energy symptom and upon opening up the cover I noticed couple of elements that had been burnt. R623 (four.7 ohm) burnt in the side and you can nonetheless recognized the resistor color code. The current sense resistor (0.68 ohm) outer layer partly had came off and somewhat burnt plus the filter capacitor c605 (68uf 400v) one of the pins had grew to become rusted and arrived off when I attempted to desolder the pin.
This just isn't a new model and I think numerous experienced techs had solved the issue. But for people who haven’t encounter this difficulty, you could utilize the process to troubleshoot and fix every other type of LCD Keep track of with power situation.
I will 1st eliminate the energy transformer and ensure that it rings okay with dick smith flyback tester. I do that first given that I do not need to waste my time checking other components and later on only located out the power transformer is the brought on from the power situation. Once it rings alright I'll measure all the secondary diode. For your facts most LCD Monitor power provide extensively used the twin schottky type diodes and also the specification in most cases in the 10 to twenty amp with about 40 volts. Then again I do come across some designed are nonetheless utilizes the ultra quickly recovery type diodes inside the secondary segment. Make sure you know ways to verify a regular diode plus a schottky diode. Refer back to my webpage in the diode section and search for testing schottky diode article. I'll then verify for the ESR of electrolytic capacitors also.
When I confirmed which the secondary side elements are all tested alright, I'd then proceed to eliminate all of the components inside the primary aspect. Some components in the main facet you are able to verify on board such as the bridge rectifier and fuse. If I’m new to the LCD Monitor product I would examine all components off board (with a lead eliminated from board). Using this way you may make sure that all components you might have scanned by means of.
These are the components that I discovered defective; fuse-2A, R615-0.68 ohm, R613- 1K, R612-47 ohm, R623-4.7ohm, D604-1N4148, Q601-SSS6N60A, C605-68UF 400V and IC601-UC3842B. Total was nine components and it took me much less than twenty minutes to examine all of the elements in main facet. Now is the time for you to research for spare elements. Right after investing about 5 minutes in the spare part compartment I maintained to find all components other than the power resistor color code. Though this part number is primarily used in swap mode energy provide, my digital supplier does not have this stock. I would then browse by way of the semiconductor databook to search for equivalent part number. From the e-book, it indicates to make use of the K1118 as alternative. Just after all components have place into their authentic location or place and needless to say with the power transformer soldered, I do not right away switch around the energy supply. I would 1st make use of a 100watt light bulb linked in sequence using the live line. The best spot to put the light bulb may be the fuse holder location. Eliminate one of the fuse lead and link the light bulb throughout it. Power it on and begin to observe the bulb. If it brightly lit and remain that way then there is certainly still dilemma within the energy supply. Nevertheless, if the bulb doesn’t light in any way then this is usually a beneficial indicator which the energy supply may perhaps be operating.
Utilize a multimeter to spot in the secondary side with power on. When you get some correct voltage reading from the outputs plus the bulb doesn’t light in any way, then this confirmed that the power provide is working. Change off the energy provide and connect again the fuse and turn the LCD Monitor on once again. I’m pretty confident the LCD Keep track of will now work.
Whether you are troubleshooting the DELL E151FP LCD Monitor or other brands, you may at all times use the process provided over to restore the energy supply trouble. This technique might be even use to restore other varieties of power supply as well. Regardless of what forms of power supply you might be troubleshooting, just make sure you realize tips on how to examine and check the simple digital components. For those who ever miss one, depressing to say you would not have the ability to solve the problem or it could just just take you countless of one's valuable hrs to complete the task. Happy hunting!

Frequently Asked Questions...
In what devics we use dc power supply to on that device in our homes ?
e.g in fan capacitor is present so we use dc power supply (battery) to on the fan.plz any one give me list of that devices which need Dc power supply to on it.
Answer:
Virtually all electronic devices in out homes have an internal DC power supply(rectifier). TVs, radios, PCs and yes macs, DVD, CD, amps, DVR, most appliances, anything with a digital display, anything with a memory, anything with a solid state controller and the list goes on and on.
