Hi

The first thing you need to check is the power cable. If the cable is fine then please make sure the power connections are clean. Also check fuses and connections. It has four wires; red, black, green, and white. Red is the positive lead, black is negative or ground. Make certain to attach the in-line fuse holder to the red lead as close to the power source as possible. You can even get a volt meter, unplug the power cable and test for 12VDC across the two bigger female contacts on the power cable connecter. If you are getting 12VDC, then the LMS-520 is bad. If you are not getting 12VDC, then you have a bad power supply, connection, or cable. If still you face the same issue then you have to service the unit, contact the manufacturer go to http://www.lowrance.com/en/Support/My-Account/ . You can also contact them by phone, call 800-324-1356, press option 1, and follow the prompts to get your RA status.


Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

My lg intellowasher won't start


Here's a fix that worked for me today! I couldn't make it turn on for over 24 hours. As a last-ditch effort I put my hairdryer on hot and aimed it at the on/off button. I waited 20 seconds and it turned on! (took about 20 presses of the button). In my mind the heat from the hairdryer is expanding the circuit board so that the things that aren't connecting can connect. Hope this helps!

Dell Inspiron 1501 Power Button won't turn on ....


I would remove the hinge / power button cover again and make sure the little pip that presses the button down it not broken, also check the little circuit board with the switch on to make sure it's not disconnected.
Try switching on with the cover removed.

My iphone 4 has been working great, just went to make a call and its dead. Won't turn on?


I am guessing that your phone probably shut itself down to prevent data loss. When was the last time you shut it off by holding the top power button until it says slide to power off and then powering it off? I may be wrong in this but,... Okay, so have the phone unplugged and I want you to press and hold both buttons at the same time, the Top Power and the Home Screen Button and just continue to hold them, sometimes even for like a minute but I'm guessing within like 30 seconds or so the Apple logo will appear then you can release the buttons. If this does work you can prevent this from happening again by power cycling your phone on a daily basis or at least every other day. :-) I hope it helps good luck.

The unit worked fine when i last used it in the fall. I plugged it back in today and all the buttons lit up for about 1.5 seconds and then all the buttons went dark again. So I pushed the "on"...


I have had a problem like this in the past you can try taking the electric access panel usually on the side of the equipment. then look inside you will see a wiring harness inside and it literally takes nothing to bump it loose. This happens when people move these units they are pretty fragile and can be tempermental. Make sure the unit is unplugged while you adjust the wiring harness. If that deosnt work your display board is probably bad. Hope that helps

I hooked the ps3 to the philips tv. turned on the ps3, AV1 displays in the corner. Nothing else happens, I am expecting the ps3 logo


give this a try...

Leave the TV running, go over to your PS3 and turn it off.

Once its off, hold the power button down till you hear a beep, KEEP HOLDING THE POWER BUTTON till you hear a double beep. The PS3 will shut itself off.

Give the device a couple of seconds, then hit the power button one last time (just turn it on, you don't have to hold it).

If all went right, your baby is back up and running...

Computer was on and was in use then the computer turned off. Won't come back on at all. It was plugged into power. When I push the power button front little lights blink on and off but nothing else...


Sounds like the battery is down so low that it won't turn on even with the power supply hooked up to it. When was the last time you changed the laptop battery? Also, check voltage of charger to make sure it can charge the battery to specs.

Turning off IPOD 1059


If your iPod is frozen or won't turn on, it may be because iPod is paused or the Hold switch is in the locked position. If so, a lock symbol appears on the screen. Slide the Hold switch to the unlocked position and check the screen.
  1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
  2. Press and hold the Menu and Center (Select) buttons simultaneously until the Apple logo appears, about 6 to 8 seconds. You may need to repeat this step.
Tip: If you are having difficulty resetting your iPod, set it on a flat surface. Make sure the finger pressing the Select button is not touching any part of the click wheel. Also make sure that you are pressing the Menu button toward the outside of the click wheel, and not near the center.
If the above steps did not work, try connecting iPod to a power adapter and plug the power adapter into an electrical outlet, or connect iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep.
To reset iPod, iPod (scroll wheel), iPod (touch wheel), and iPod (dock connector) ipodg1-2.gif ipodg3.gif
  1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
  2. Press and hold the Play/Pause and Menu buttons simultaneously until the Apple/iPod logo appears, about 6 to 8 seconds. You may need to repeat this step.
If the above steps did not work, try connecting iPod to a power adapter and plug the power adapter into an electrical outlet, or connect iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep.
If you are still unable to reset your iPod, use only one finger from one hand to press the Center (Select) button, and one finger from the other hand to press the Menu button.
When you reset iPod all your music and files are saved, but some customized settings may be lost. Date and time are preserved (unless the iPod reset itself because it had no power and then was reconnected to power). Other customized settings, such as Bookmarks, On-The-Go Playlists, Shuffle, Backlight timer, and so forth are preserved from the last time the hard drive turned on.
