HT2811 If the display flashed short long short could the power supply be bad?

If the display flashed short long short could the power supply be bad?

Hello,
In order to determine what might be going on, I am going to need a little more information about your setup such as:
-what version of the cFP drivers are you using?
-where/what device are you outputting voltage to? at what voltage? how much current do those devices require?
-could you explain further by what is meant by '[at] approximately 30 seconds, all channels on that PWM shut off'. Are the lights on the modules still illuminated when the system 'shuts off' or do they remain on?
-Do you have another power supply you could try this with?
-Does the power supply meet the specifications for use with this module per p. 4 and 5 of the FIELDPOINT AND SPECIFICATIONS™ OPERATING INSTRUCTIONS FP-PWM-520 and cFP-PWM-520  Eight-Channel, 5 V...
-Does the power supply continue to output 24VDC even after the 'shut down'?

  • HT2811 So, my cinema display is sending short long short...

    Okay, so my cinema display is sending short long short. That means I have a pwer supply probem, apparently.  But I have two screens and so can swap over the power supplies; the one giving the error message continues to err, so the fault is not with the power supply but with the screen itself, right?
    The screens having been working perfectly for years (five?). All I did was carry them between buildings. A static charge is a possible occurrence here in a dry part of China. The screen has working ports - the keyboard I am using is driven by the faulty screen (the screen procaliming a fault, really).
    What am I missing? I'm out of ideas - and, being China, help is a long way off.

    You uhave to buy a 150 Watt power supply to make it work again. its a well known problem.

  • Apple Cinema Display 23" - Blank Screen, "short-long-short" LED code

    Hello everyone.
    This sounds like something of an epidemic... My Apple Cinema 23" HD Display (bought Dec. 2007) hasn't been turning on after a power outage hit our area last week.
    The Computer and Display were OFF when the outage occurred. Everything was plugged into a surge suppressor. Everything ELSE plugged in to the suppressor is fine (including my Mac CPU)... but not the monitor.
    It’s not dead-dead…. It’s a blank screen but there IS a morse-code flash on the LED (short-long-short). According to Apple Support’s LED Translation, it SHOULD be something to do with the power adaptor. The adaptor IS correct… a 90 watt… but just in case I bought ANOTHER 90w adaptor brick. I plugged the monitor to the new brick. THE RESULT WAS THE SAME.
    I’ve tried power cycling, I’ve tried plugging it into different outlets, I’ve tried connecting to other computers. The same LED result remains.
    And, yes, of course, I’ve got no Apple Support, and from what I read in similar posts, outside-the-warranty repairs could hit around $400. I REFUSE!
    For now I have a Samsung monitor from Costco. It’s not bad, but it’s not the Apple monitor with its awesome color-fidelity.
    I've read some other posts with the same problem (LED blink code and all) elsewhere but haven't got a solid answer.
    I wonder… has anyone else incurring this same problem (with the same LED flashing deal) tried to use a 150-WATT adaptor brick? I would try this myself, but I’m currently financially unable (and personally unwilling) to throw more cash at this problem unless I know it’ll fix it.

    Hi all!
    As mentioned on the title of this topic *I HAD THE EXACT SAME PROBLEM* with my 23" Cinema Display...
    Before the failure, the monitor *WAS IN PERFECT CONDITION* (trust me when I comment this, my whole life is in front of a monitor)
    *THE PROBLEM SHOWED UP THE DAY I MOVED THE MONITOR TO AN OTHER OFFICE* (???). Please note that *I TOOK EXTRA CARE WHEN I MOVED THE MONITOR*, besides, when something costs around 1K you owe to.
    *I TRIED AN 150W ADAPTER ON IT AND WORKED FINE!!!* Just like before.
    But since *IT WAS UNDER GUARANTY* I sent it to the local distributor who eventually *REPLACED IT WITH A "NEW" ONE*, which after remarks from my side it turned out it wasn't "new" but re-manufactured by Apple (off course, he guarantied me the parts in it, where brand new and had 0 hours of usage).
    In my question to the technical representative of Apple *"WHAT WAS WRONG WITH MY MONITOR"*, he answered me that *THE INVERTER WAS FAULT*.
    After that I questioned him *"WHY MY MONITOR MANAGED TO WORK WITH THE 150W ADAPTER?"*, he answered me that *THE EXTRA CHARGE OF THE 150W ADAPTER WAS ABLE TO "EXCITE" SUCCESSFULLY THE FAULTY INVERTER IN ORDER TO WORK* and that *IT WAS A MATTER OF MONTHS FOR THE MONITOR TO FAIL AGAIN*.
    That's my story... I hope it may help some of you... Personally I can't have an opinion on the matter, since I'm not a technician. The only thing on which I can comment is that *A 1K MONITOR SHOULD BE WAY MORE DURABLE AND TOLERANT WHEN YOU TRANSFER IT AROUND (if that cause the problem of course)*

  • I am trying to connect my laptop to my TV. The computer flashes blue after I plug the cable in but the TV says there is no signal. I have a Mac Book Pro 2009 and a Samsung 32" Class (31.5" Diag.) 450 Series 720p LCD HDTV (2010 model)

    Hello,
    I am trying to connect my laptop to my TV. The computer flashes blue after I plug the cable in but the TV says there is no signal.
    I have a Mac Book Pro 2009 and a Samsung 32" Class (31.5" Diag.) 450 Series 720p LCD HDTV (2010 model).
    I am using a mini display port to VGA adapter. I have sucessfully hooked up boh devices but it stopped working after a handful of times. I was wondering if there is anything I can do to fix the problem or is my cable broken?

    Some things you can try.

  • I have the Acrobat X Standard, the tool box no longer gives me the options I had before like splitting documents. Please help!

    I have the Acrobat X Standard, the tool box no longer gives me the options I had before like splitting documents. Please help!

    Was it AA X Std that you had these options in (sorry, I only have Pro)? If it was the trial (that is Pro), it may be that Std does not have to feature. Under XI at the Adobe site, there is a comparison of features between Std and Pro that might give you a hint.
    There is also an option to turn on or hide many tools. For me there is a small icon just above the tools...comment titles. If you select that it give a list of tools you can display. Often, several are not displayed by default. How you lost them is another things, but it is getting them that is the basic question.

  • The charging cable now longer fits all the way in the charging port.  I can't see if any lint is in there, but if there is how can I get it out?

    Go to the Music section of your Library (very top-left corner) and see if your songs are there. The "Purchased" playlist may have been deleted or gotten corrupted, but if that happens it's not a big deal because your music should still be in your main Music Library.
    If your music is NOT in the Music section of your Library, then go to the iTunes Store homepage and find the Quick Links list on the right side. At the top of that list, click Purchased and you can redownload all of your previous content that you might have lost.

  • Why is the Black Swan no longer available in the US store?

    Why is the movie the Black Swan no longer available in the US store and does any know when it will again be available for purchase / rent?

    Hi...
    This being a user to user forum, not Apple, we have no way of knowing Apple's policy regarding the availablity of movies sold or rented from the iTunes Store.
    However, you can start a wish list.
    In iTunes, click iTunes Store (below Store).
    Find the song, video, or album you want to add.
    Click the arrow to the right of the Buy button for the item you want to add:
    From the menu that appears, choose “Add to Wish List:”

    Hi and welcome to the WD community.
    Try to see if perhaps you are connecting the drive to a surge protector and it might not be getting enough power, try to connect the adapter directly to a power outlet on the wall to see if you get a different result.

    Hi, I'm trying to shut down the phone in the normal way (the Sleep / Wake button and hold down on the Close tab) turns off the display after a while yet, but the phone turns off completely opens up the phone to come out after the apple logo .. What is the reason I'd appreciate if you help how to fix it ...pleasa help me

    Doing those doesn't turn off your phone?
    As stated hold down the top button only until you see the red slider to power off your phone.
    If that doesn't work then take it to Apple and see what they say.
