    Hi and thanks for a quick reply however, this seems to be an educated guess and not a answer. Going on line I find that this has been a common problem with the ZOOM for others so there must be some experience with the actual repair. Would appreciate further advice. Thank you... RMT

    Unfortunately I could find no real answer but appreciate the attempts. I will probably have to send it back to the factory for repair. OUCH. Ray Toney

If it at least open to lit the display ..than you should look for a reset button ...that may be hidden in a hole and need to be pressed with a sharp object ..if it has one ...power it up ..and reset it ..after that it should work , if it doesn't have a reset button ...remove any power source on it ..and leave it be for a few hours...and see if ti is reset after that ..In the last case ..if you seam to have a power response at least ...download and reinstall the firmware form the support site..
But ..from what I sow you described..it seam more like a power issue ..and it doesn't receive power ...and in this case you have to open it up ..and check the connections ..or the motherboard is fried..

I couldn't find any report of this on the net but it sounds like a broken power switch, or some power issue. If it's new or under warranty, have it serviced or replaced, as they often do these days.
If it's out of warranty, you will have to try to determine the problem, or have it serviced. Some switch contacts can be fixed, but some can't, since they're built into the circuit boards, and require the whole board to be replaced.
Refer to your literature for manufacturer support, or go here http://www.zoom.co.jp/english/products/h4/ and see if they can help, reasonably. Otherwise, you can try to fix it yourself. Power charging jacks can get oxidized, or sprung, and you can clean them with some electrical contact cleaner, or respring them, so to speak. Sometimes you can clean the switch contacts also, but not always.
Good luck, and hope this helps.

My yamaha psrE23 not responding when plugged to electricity what maybe the problem if I put batteries it's just giving me a feedback


Hi
In terms of no electrical power it could be either a faulty power adaptor, broken socket. However the feedback with batteries could indicate a more serious fault. If the batteries are know to be good try a reset. Hold down the highest sounding key while turning the keyboard on. Release once you have lights or a display on screen. Has the noise stopped? If so then try electrical connection again, if still no power ensure you are using the correct power adaptor and see if it works if you wobble the connector - they break away causing an intermittent fault. Report back and maybe I can offer more advice depending on how you progress with the above.

Cannot turn on my laptop only the start button light turns on but no screen display and a few noises help


This is only the first of many things you may need to do to determine the fault. But it is a process for determining the exact cause.


Make sure the ac adapter is correctly plugged into the notebook and into the power cord.


If everything is plugged in correctly and it still will not power on, follow these steps to complete a 'power reset' of the notebook.

  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

Laptop won't power up dies in the middle of movie-won't power up


You would probably be better off buying a new notebook. Not sure how tecnologically advanced you are but it seems you already did the troubleshooting yourself. But i am very interested in the a/c adaptor output. If the led on the adaptor is green that just means that it is getting power from the wall.

What did you mean by fluid leaking out?

It could be the mobo (motherboard) or it could be the connections from the power to the machine. If you want to put a new mobo in I have to warn you that taking apart a laptop is VERY difficult and I do not recommend this unless you are a PRO. This is just about the only link i can find to buy a new board. If you google your laptop model you will find out you definately are not alone with this problem

My psp wont turn on!


  • Hi! TRY THESE TO SEE IF WE CAN GET YOU POWERED UP! :)



    Confirm the system is not in HOLD mode

    Make sure the PSP system is not in Hold Mode (in the down position). Slide the Power/Hold switch up to clear Hold Mode. Or try sliding the Power/Hold switch up and holding it there until the power indicator light turns off and the PSP system is completely turned off. Then try turning the PSP on again.

    • Confirm the backlight is ON
      Make sure the LCD screen's backlight is not turned off. If it is, press any button to turn ON the backlight.

    • Confirm use of only licensed products (AC Adaptor, battery pack and charger)
      The AC Adaptor, battery pack and battery charger must be licensed for use with the PSP system. All licensed products for use with the PSP will have the following logos displayed directly on the product and/or the packaging:
      pslogor.gif global_logos_psplogo_168x35.jpg global_logos_scealogowhite_60x73.gif
      If any of the products you are using does not have these logos on them, we recommend that you immediately discontinue the use of these products, as they void the PSP system's warranty, and can cause damage to the system. See compatible peripherals for the PSP system for a full list of supported products.
      There are some products that can be used with the PSP system that may not display our logos. Products such as San Disk 1GB Memory Sticks, or various USB cables, needs only to be genuinely certified. Look for the genuine certified logos on these products or contact the company which manufactures these products for more information.

    • Confirm the battery pack is correctly inserted
      Make sure the battery pack is in its proper position (see inserting the battery pack for details).

    • Try the battery pack only
      Unplug the AC adaptor from the PSP system. Make sure a charged PSP battery pack is inserted inside the PSP system. Turn on the unit. If you get power, then the problem may be with the AC adaptor and power cord.

    • Try the battery pack in a different PSP system
      If possible, try your PSP battery pack in a different PSP system. If your battery works on a different PSP system, it may indicate an issue with your PSP system.

    • Try a different PSP battery pack
      If possible, try a different battery in your PSP system. If a different battery pack does work on your PSP system, it may indicate an issue with the original battery pack.

    • Try the AC adaptor and the PSP battery pack
      Insert the battery pack and plug in the AC adaptor. If you still do not get any power, your PSP system may need to be sent in for service (see PSP Service for details).

    • Try the AC adaptor / power cord only
      Turn off the PSP system, unplug the AC adaptor, and remove the battery. Now plug in the AC adaptor to the PSP system with the battery removed. Confirm the AC adaptor and power cord are firmly connected to each other. Now make sure they are also firmly connected to the PSP system and the electrical outlet.
      If the PSP system powers on, the battery may need to be replaced.

    • Check AC adaptor and power cord for damage
      Visually inspect the AC adaptor and the power cord for damage. Do not use if frayed, cut, or damaged in any way.

    • Check the electrical outlet
      Confirm the electrical outlet that you are using is active (receiving power). Try using a different electrical outlet.

    • Try a different AC adaptor and power cord
      If possible, try a different AC adaptor and power cord. If a different AC adaptor and power cord does not work, the PSP system may need to be sent in for service (see PSP Service for details).

    • Confirm no unauthorized system software or downloads were used
      Confirm that you have not used any unauthorized system software updates or downloads on the PSP system. Use of such unauthorized firmware updates voids the warranty and can damage the PSP system.

    • WLAN turned off
      Make sure the wireless (WLAN) network function is not in use while charging. The battery pack cannot be recharged when the WLAN function is being used.

    • Power surge
      If you experienced a power surge, shortage, or a lightning storm in your geographical area recently, this may have affected the PSP system's power supply. Please contact Consumer Services below for information.

    Toshiba Satellite 1405 - Power problem


    Hi Don

    Although symptom is showing that AC Adaptor is not working as its not providing power to the unit. I will suggest you to perform some basic troubleshooting steps. Check if outlet is working if not check with known working outlet. If you have a multimeter you can the output of the AC adaptor.

    Also you can perform full power cycle and component discharge. Take the battery out and disconnect the AC adaptor press the power button and hold about 7 seconds. After that put the AC adaptor in and test again.

    If issue persist take to nearest Service center check with known working AC adaptor. After that I believe you will figure out the best solution.

    Good Luck

    No power via batteries


    The batteries are put in wrong, or there no good, or the dc jack in the back still has the plug in it for the ac adaptor. You see theres a small switch on the jack inside the unit that switches from the ac adaptor to the batteries, when the jack is iserted. Also if the plug is not pluged into the jack, then there could be a bad jack or a broken solder connection on the jack inside on the printed circiut board. good luck
