    Is the Plague Over ? What do you think ?

    I've been repairing LCD monitors for about a year now and was wondering if anyone has found bad caps in any new units say made since Jan 2008 ? My log shows I've done or diagnosed about 40 in that time and they have had mfg dates in the period of Sept 2001 to July 2007, most dating in 2003 -2005 period.
    Today I'm doing an Acer 19" of 07/07 make.The P/I board is a DAC-19M005 Rev.01A, and it has CrapXon KF caps and at least two are bad. My question here is not what we do but what we find.
    So...What is the latest dated LCD you've done with bad caps? Do you find that the new units have less bad caps ? Do you think we are running out of bad caps and the 'plague' is finally over ? Are you finding any good manufactured caps in your newest LCD's, or TV's ? I suppose there are monitors being made with surplus power boards which were made in earlier times with bad caps.
    Let us know what you see .....

    In a lot of cases it has nothing to do with the cap manufacturer, but simply the design of most PCB's put the caps very close to the heat generating components, ie Schotkys and Heatsinks,and so over time they will dry out and fail, so a long way to go yet I suspect.

      "The plague" is over. Crap caps and manufacturers are not. As long as there's a buck to be made, they will exist.

      It all follows "planned obsolescence". 3 years and it's time for a new TV, video display, computer, DVD player, etc.

        I've just bought a Panasonic TX-P42G20E Plasma TV. Iøve peeked inside it, and its full of Rubycon's and a few Nichicon caps. Seems like good build quality.

          Interesting I would have expected Panny caps in a Panny TV.
          I love putting bad caps and flat batteries in fire and watching them explode!!

            The plague will never be over as long as there's corporate greed and planned obsolescence. The things that all the techs repair on this site and everywhere else are just the crumbs. I'd render a guess and say that 90% of consumer products that have failed from bad caps have been replaced with new and are now landfill....just as the manufacturers wanted. We, the repair guys, actually see very little of this stuff.

              Funny that you say that, I have also been wondering.
              About 3 months ago, my mon bought a Panasonic HD recorder. I also took a little look inside that, and the powersupply caps are Nichicon, rest is Elna.

                Perhaps the LED backlights will end some of the repair issues, but I expect more, not less of suboptimal quality builds in the future as margins narrow...

                  All caps fail eventually. The quality only determines how long they will last. Caps can fail early due to impure aluminum, substandard electrolyte, too much heat, poor construction, or abusive circuitry. The supply of designers willing to cut corners hoping for a quick buck is unlimited so the supply of low quality products that fail early due to capacitors is also unlimited.

                    It's interesting that here in Ireland, with the recession, banking crisis etc, a lot more people want to get things repaired rather than replace with new. They can't affort it any more. I'm finding that customers are surprised by repairability of many consumer products. (Almost alway CAPS). I agree, we will see more repairs and slightly less landfill.

                    For the record the latest monitor on the bench is yet again a Dell branded BENQ E172FPb, 4 nicely toasted 'Elite' EL series caps, oh and 2 more TK series! All have late 03 or early 04 mfg datecodes.

                      The Plague is absolutely not over.

                      The plague is defined as premature failure of large quantities of specific brands and/or series of caps that is not tied to a specific make/model product.
                      - This clearly indicates a problem with the specific brand and/or series of capacitors as parts and not a design flaw in the equipment they are used in.

                      By that definition the Plague existed -before- the 'Stolen Electrolyte' saga and -before- the HN & HM crisis.[*]

                      Caps made with Chinese mined Aluminum have excess and different impurities than caps made with more pure Japanese and USA or European Aluminum.
                      Those impurities very often cause the caps to fail at between 1 and 3 years old. [Which anyone with common sense would consider premature failure.]
                      See [**]

                      That 1 to 3 years is -exactly- why you usually see monitors from about 2008 and older showing up in 2010 with bad caps.
                      [Even the HM/HN issue took ~2 years to 'show up'. Only stolen electrolyte issue was faster because those failed faster.]

                      That Aluminum is sill in wide spread use in Chinese, Taiwanese, and Malaysian caps.
                      In fact it' is used in the majority of capacitors made there.

                      - As long as that Aluminum is in use, the capacitor plague still exists.

                      If you want to verify that take a peek inside a 2010 monitor and see what capacitors were used.
                      If you -like- repairing monitors you should get a warm fuzzy by what you see in there.
                      .
                      .
                      .[*] The capacitor plague is generally considered to have began in 1999 and the problems with 'stolen electrolyte' and bad HM/HN didn't even occur until two years later in 2001.

                        In the job that I have the plague will never be over. We buy alot of used equipment, 100's of computers the people that do the buying are not careful to the brands or models nothing matters to them as long as they can run xubuntu linux which takes pretty much no power. I have repaired 32 motherboards this year it would be more but I have trained two other people to do most of my normal recaps. Now they have tasked me with monitors which I have been learning on this site to repair. I also double as the system administrator with over 280 servers. It's crazy how many acer monitors i have repaired in the last 3 months we have over 1000 in the field and a couple die per week and need to be recapped. With the volume of equipment that me and my crew replace no matter how well the product is built we will have failures and I will be recapping them or repairing them in some way shape or form
