This model of lcd monitor I had received a lot of my protech2u.com subscriber requirements. All are regarding service manual and how-to repaired the dell e151fp lcd monitor. So I decided to write this repaired notes to you.
Last year until now, I had repaired many of this model lcd monitors. But most of the problems are no power or power on about 3 second then power cut off. Actually Dell E151FP Lcd monitor are make from Acer (Acer FP553 Chassis). The damaged components need to change are all the same. When I first time repaired this model lcd, I used about one and half hours to solve these problems. After I had these repairing experienced on dell e151fp lcd monitor, I just used about ten minutes to solve these type of symptoms.
After you read this useful note, then you will know which parts or component are easily damaged and you can quickly check these first. Finally these tips are save you a lot of time and money. Below are the lists of common defective components at the Dell E151FP LCD Monitor.
Symptom: No power or power comes up a while then no power.
1) F601= 2A Fuse
2) C605= 68uf 400v (must change)
3) R615= 0.68ohm 1watt
4) Q601= SSS6N60A
5) R613= 1Kohm 1/8watt (value changed to 2.3Kohm or higher)
6) R623= 4.7ohm 1/8watt (value changed to 7.2ohm or higher)
7) D604= 1N4148
IC601=UC3842B
9) C707 & C703= 1000uF 16V (must change, because of bad ESR value) secondary filter capacitor.
Sometime, this model lcd also have some others problem, like display darkness. This problem of dell e151fp lcd monitor, you just need to resolder the inverter section (bad points or dry joint) and also check the capacitor value with ESR meter. It will solve your problems.

All About Hybrids
For most of us the act of purchasing a new automobile can be a very stressful experience. No wonder, with car and fuel prices reaching into the stratosphere. Gone are the days when the biggest decision was the size of the engine or color of the interior. Now we are subjected to a barrage of green tech jargon and a carbon footprint guilt trip to boot. So how can the average consumer make the right car purchase given todays high tech information overload?
Apart from the complexity of the underlying auto technology, one has to realize that the sales person is not a friend. He or she is only there to make a sale. If the buyer is ignorant of the various car technologies then the sales person has the upper hand in making a deal. So it is wise for the average car buyer to brush up on the latest automobile technologies before visiting the local car dealership(s). At least memorize the technical jargon in order to appear knowledgeable. That way the sales person will be less likely to take advantage of the situation.
So lets get down to business. The first thing to understand is that if you are buying new, you will likely be buying a hybrid vehicle. So what is a hybrid? The short answer is that a hybrid has two power sources and they are generally gasoline and electricity.
There are three broad types of hybrids: series, parallel and series/parallel. A series hybrid is one in which the two power sources work in series. Usually a gas engine turns a generator to either power an electric motor or provide charge for a battery. The Chevy Volt is an example of a series hybrid.
A parallel hybrid is a vehicle with the power sources, typically a gas engine and an electric motor, operating in parallel to move the vehicle. Honda provides some parallel hybrids.
The third and most prevalent type is the series/parallel hybrid. This type of hybrid can function in multiple configurations including both series hybrid and parallel hybrid. The Toyota Prius is an example of series/parallel hybrid.
Hybrid Synergy Drive (HSD): The original Toyota Hybrid System (THS) used in the 1997-2003 Toyota Prius. Now the name has been changed to Hybrid Synergy Drive to accommodate usage outside the Toyota brand. HSD is a refinement of the THS. Toyota describes HSD-equipped vehicles as having E-CVT (Electronically-controlled Continuously Variable Transmission).
Integrated Motor Assist (IMA): Honda's hybrid car terminology is called Integrated Motor Assist. The technology was first introduced on the Honda Insight in 1999. It uses an electric motor mounted between the engine and transmission. The implementation employs a parallel drivetrain.
Two-Mode Hybrid System (TMHS): Most 2008 hybrids do a good job in stop and go traffic but not highway usage. The Two-Mode system increases fuel efficiency above 40 mpg by use of a re-designed automatic transmission. GM has introduced this technology on the Chevrolet tahoe and GMC Yukon 2008 hybrids with more models to be converted over in 2009. The 2009 Chrysler Aspen hybrid will also include TMHS.
Super-Capacitor Hybrid: This technology, being developed by BMW, is a variation of the gas/electric hybrid. Instead of using a stack of rechargeable batteries for implementing the electrical power storage medium, BMW is using super-capacitors, thus making the car lighter, faster and more fuel efficient. As with the original hybrid concept, energy is recovered by regenerative braking. But instead of charging batteries, super-capacitors are charged instead. The capacitors store less power but unlike rechargeable batteries, all 100% of what is stored can be utilized. A 20% improvement in fuel efficiency has been reported with this technology.
Micro-Hybrid: The micro-hybrid is an initiative similar to the HEV, but without the large battery. The micro-hybrid, also called "stop-start", causes the engine to stop idling during car slow down and stop conditions. This fuel efficient technology saves an estimated 5% - 15% for city driving and comes with a much lower price tag than full blown hybrids. Stop-start was introduced by Peugeot-Citroën on the Citroën C3 in 2004 and will be installed on most Peugeots and Citroëns in the EU on or around 2010. One big advantage of the micro-hybrid is that it is easier to implement and less expensive than other hybrid technologies. It is now also being combined with other fuel efficient hybrid technologies.
Now you are good to go (to the dealership). Armed with lots of buzzwords and even some acronyms, the sales person will be at your mercy. Now this whole exercise won't prevent you from spending too much money or buying the wrong car. But it will help you cope with your feelings of inadequacy long enough to sign the sales agreement.

Does anyone know a way of keeping a HID capacitor cool for outdoor lighting?
I keep losing capacitors to the heat… I am using 105 degree Celsius rated caps but now I am looking for some strategies for keeping them cool another way. The caps and ballast are being used for outdoor parking lot lighting in hot areas.
Those enclosures are supposed to be designed with temperature
control as a factor.
Just some W.A.G.s.:
Is this a 'refit from M.V'. situation?
(A step down in Wattage might be indicated.)
Are there any blocked cooling passages/vents?
Is airflow around the ballast compartment restricted?
Are the fixtures hard against the inside of a precast 'pan'?
(Sometimes even a short stand-off nipple can give you some
more space for convective flow.)
