    Multiple Standards Confound Power-Supply Designers

    Multiple Standards Confound Power-Supply Designers
    The melange of energy-efficiency standards used to be good for a “green” label. But how much difference really exists between them?

    What's a poor power-supply designer to do? The U.S. alone has four standards for energy efficiency: Energy Star, Executive Order 13221 (1-W Standby), 80 Plus, and the regulations of the California Energy Commission.

    Europe grapples with at least seven: the International Energy Star program, Blue Angel, the Group for Energy Efficient Appliances, the European Code of Conduct, EU Eco Label, Energy Plus, and Nordic Star. Then there's the Australia Greenhouse Office (Australia also participates in Energy Star), the China Energy Conservation Project, Korea's Energy Saving Office Equipment & Home Electronics Program, and Japan's Top Runner program. Many similarities weave through these programs, but there are enough differences to make powering a product for a global market an exercise in anxiety.

    Fortunately, many of the programs are voluntary. Therefore, you could still play in those markets even if you don't meet their standby power of efficiency specs. But you won't get the compliance sticker, which would mean mean you'd most likely be positioning your brand as a "value leader" while sacrificing your profit margin.
    Voluntary today will be mandatory tomorrow - unaccountable bureaucracy at work. My favorite examples in this article of what I regard as lunacy are California's agency that waved a magic wand and decided that standby power for set-top boxes would be 1/3 of current devices - "Make it so!" - and Japan's progressive goal-post moving scheme.

    Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

    Pete,
    I don't give ass of rat so much about my boxes (plural) standby power.
    It's the heat the burns me, and that is wasted power.
    Just curious, what is the moving of goals?

      From the article:
      Then there are the Japanese standards; different, practical, and frustrating—all at the same time. The Japanese pick the most efficient product in a particular market and let it set the specs that everyone else will have to live up to in a few years, at which point the goal posts will be moved again.

          just think where we would be today if tv sets still drew 400w and were the equivilent of a 400w space heater....and wasted 100w in standby keeping 30 tubes warm for fast startup!i have a few totally restored examples of early color tv sets.i mostly play them and the old boatanchors like my hammarlund hq180 in the winter when a bit of waste heat is ok.

            Concur kc8, though those improvements were made by industry initiative, as have been almost all progress in P/S efficiency.

              kc, I was an old color tvaholic once.
              Bought big old consoles from a barn auction out of Frisco.
              I fondly remember every one and only hope they are not landfill now.
              I'd really like to see pictures, please start a thread.

                Powersupply has all the voltages - Monitor still no power
                by Capacitorial
                Hello guys,

                I have a Philips 240B7QPJEB. The monitor seems completely dead.
                I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
                On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
                The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
                The weird thing is, that the Power LED is powered over the TCON board.
                On The TCON...

                30V 3A Powersupply - regulating only to 8V
                by worldofskin
                Hey guys! i build a 30V 3A powersupply. My friend blown it... He connected cables to the wrong connectors. I changed the op amps, shorted zener diode and a 9014. Now the powersupply works again but only to 6V. When i measured the caps they looked in spec. But after i connected 2200uF cap on the main power rail parallel to the C1 - 3300uf one - output voltage is now regulatable to 8v. Any idea where to look ? or what to do ? R1 and R2 are getting hot. The input of the transformer is 40V after rectifiers. Its a 24V transformer on 230V mains voltage....

                Have to turn on 77” LG C1 multiple times to get to come on
                by Msb1xr
                Have to turn C1 on and off multiple times for it to fully come on

                Have to run LG C1 on multiple times for it to fully work

                If I have it off for a while I have to turn the TV on and off and handful of times for it actually display what it's suppose. The times it doesn't nothing comes up like the input or dobly vision logo. Once it's on I can turn it off and back on fine and the picture looks perfect.

                Unhooked everything except antenna. Reset tv to factory settings. Let it sit and when I tried 2hrs later turned TV on and sound comes through but no picture....

                Troubleshooting Apple Multiple Scan 17 Display
                by nicktasios
                I recently picked up a Quadra with a Apple Multiple Scan 17 Display. The Quadra was not working, it clearly had corrosion from leaking caps so I replaced them and luckily it chimed and worked properly.

                The next problem to tackle was the screen. Sometimes it turns on and off multiple times before finally turning on, and then it sometimes turns purple. After waiting some time, without doing anything, it regains all colors. Another symptom is that it sometimes seems to momentarily blink.

                Also, not sure if this is related, but sometimes, after experiencing these problems,...
