    Hello everyone!

      Re: New Members - please post your introductions here

      Hello all,

      My name is Guy and I'm from England. I'm a electronics hobbyist and I'm also a professional hardware support technician -- a position which I've held for almost a year. I care about quality in everything that I do, and designing and building electronics is no exception.

      I've met a lot of bad capacitors throughout my life, and my job is no exception to that. I've had the misfortune of having to repair some Dell Optiplex 745s that constantly have the same 5 bad capacitors over and over. I mostly use Nichicon HE and Panasonic FR capacitors to replace them as I like to know that my repairs are going to last.

      I'm glad to be a part of a community that cares about quality.

        Hello all,
        a used 20" iMac G5 that lasted 6 months has given me a new project.
        Looking forward to reviving it!

                  Hi am Phil and I graduated with Biology degree so have little knowledge in electronics. Except few topics on caps, resistors and inductances my physics teacher talked about. All the same i managed to fix my laptop fans which i was very intrigued. I am from central virginia. yeah and i hope u be easy on me hear since am still learning something here. I am planning to go back to school for electronics. hope this forum will be fun.

                    Hello everybody. My real name is Ken but I prefer to go by Spork Schivago. My friends call me Spork, Captain, Captain Doctor, Doctor Schivago and some times Captain Doctor Spork Schivago. Just so you know, I do not have a doctorate or anything. I once owned a boat though. I used to program for a company named Deposit Computer Services, Inc. I also repaired computers and helped administrate their network. Right now, I work at home fixing people's computers. I love doing technical stuff and I have been getting into taking someones schematic and soldering all the necessary components on it to make it work. I wish I knew a lot more about digital electronics though.

                      Hi everyone, my name is Ray. I'm troubleshooting an Acer AL2416W LCD Monitor which has lost it's Red color. I learned to work on TV's in the 60s when my father would repair them. I have done little to keep up with the technology since so I'm sure I have alot of big gaps in my knowledge of electronics repair. I'm here to learn what I can.

                            I currently work as a maintenance technician in the Phoenix Arizona region. I wear a number of "hats" doing everything from building computers that control analytical test equipment to electronic repair of said test equipment, to machining fixtures and parts when necessary. Currently I have eight pieces of test equipment that require an AGP motherboard due to an AGP Matrox Orion video card necessary for image overlay operations. I built the computers in 2006 with ASRock Dual Sata II motherboards that have run flawlessly until now. I've had two motherboards die in the past month with the same condition. When I try to power them up the CPU fan comes on but nothing else, no hard drives, no floppy or CD drives, no video, no post attempt. I've replaced caps in hundreds of Dell and Asus motherboards over the years and these two boards' caps appear to be ok.
                            I have a Bob Parker Blue ESR meter that I've spot checked a number of the capacitors with. Does anyone have any experience with this particular motherboard? I've already used the one spare I had in stock and so far haven't determined what is causing this failure. I've looked for used boards online as well but really don't want to buy the same board if I can't repair them in the future. Thanks.

                                Hi Guys,
                                another Brit here...not a trained engineer/tech but like to think a bit of knowledge/common sense can give a new lease of life to my gear.

                                My mum was a war child (WW2) and hence I grew up never wasting anything unless unavoidable. At some point I realised that even REALLY complex devices sometimes had simple fixes to give them a new lease of life. Darbey's Law states that, if you take something that's broken apart and then put it back together again, 50% of the time it will work. For the other 50% it seems that badcaps are at fault.

                                My current project is a plasma tv that I couldn't bear (or afford) to throw out. I've replaced the bad caps on the board, replaced the power supply and am now looking at problems with the SUS boards...I'm not giving up and I'll see where the ride takes me!

                                Nice to meet you...

                                  Thanks for letting me in. I looked at a power supply for a flat screen monitor I bought for a buck, noticed some of the electrolytic capacitors on it had blown out. Googled it the mfr name(CapXon), and found this forum. These capacitors ARE crap. Four on the power supply board, two 220 microfarad, two 1000 microfarad. Voltage is 25V. Only four used, and all blew out. Their crap gave me an ultracheap monitor, one buck initial investment, maybe seven bucks in parts equals a used flatscreen that has already had its weak part shown and maybe eliminated. I'm going for exact duplicate caps tomorrow. Radio Shack had the caps in 35V, and I was afraid to use them. Am I right in doing so? It seems the power in joules held would be twice as much. I think they are on the low side of the transformer circuit, haven't checked for sure.

                                    Another thing-has anyone known if a HP G70 had the same problem as some of the other HP laptops with the NVidea chip getting loose and having to be reset with a heat gun? I have a bad motherboard on this one, and got instructions on ebay for resetting it for the HP dv 6000 and types like it.

                                      For a lcd monitor, especially on the power board, you require low ESR (ohms) capacitors. Radio Shack is unlikely to carry such caps. They sell general purpose caps. The difference between the two can be an order of magnitude.

                                        Burke, if you haven't already, I sugget you start a thread about this in the Monitors forum, and provide the info from the cap. The mfrs rt mentioned - Nichicon, United Chemicon, Rubycon, Panasonic - are all good, but they offer lots of different types of products. Knowing the Capxon serie will help folks cross-match the Capxon parts to similar but more reliable parts from a good mfr.

                                        A capacitor is an energy storage device, not an energy source. So a 100uF capacitor charged to 10V has in it the same amount of energy, whether it is a 16V part or a 25V part.

                                          Found this forum searching for an apparently common problem for a Dell 2005fpw. Looking forward to opinions on the power board as I can't see anything obviously wrong with the pcb/caps.
