    it just clicks once or twice and it doesn't move at all. It overheated so we waited like it said for 15 min. Then tried again and it wouldn't ever work again. Chamberlein sent me a new logic board, and it still doesn't work. Brand new machine too!!

    What does it do and what caused the motor to overheat? Why didn't you call for warranty service?

Ps3 disc spin


PS3 blu-ray drives are famous for this fault. sony know about it just like the YLOD fault but claim not responcabillity. which just sums sony up as a whole really.the disc wont spin as the motor that rotates the disc has shorted out (mainly due to poor parts i.e not brand new) as sony SHOULD be using.
sometimes the solder under the motor heats up so much it just melts and in turn also melts the contacts, thus stops the disc from spinning.
if your good at soldering and are patient, you could have ago at resoldering it again. then send sony the bill!! or do the easy way, open the ps3, remove the blu ray drive, take off the logic board (the main chip board at the bottom of the drive) and buy another drive from ebay. tip for you though, if you have a 60gb ps3, get a blu ray drive from a 60gb machine, if you have a 40 or 80gb get a drive from the same model, etc etc, you need the logic board as they are paired to the motherboard in the ps3, another cheap way sony tried to stop people fixing them and trying to force people to pay them for repairs. LMAO! anyway, when you get the other drive, just plug all cables in to your logic board and disgard the one the drive came with (the new drive i mean) and pop the drive back in once you get the bottom screwed back on, close the top, and that should be you all set again. hope this helps

Hi, My g. door opener doesn't work. The


5 Blinks on the logic board LED indicates that possibly the motor has overheated. If you have unplugged the unit and waited minimum of 30minutes before plugging it back in, and it still will not operate, then the logic board will need to be replaced.
I hope this helps

When my i-pod is attached to my computer it works and when it is


You need a new battery then. You can order one online for a reasonable price and installation is fairly easy. I have posted two web sites that sell batteries for iPods as well as step by step instructions for the click wheel iPod models. www.ifixit.com
iPodbatterydepot.com
Top Case Removal Begin by using a flat tool to separate the white plastic front case from the silver backcase. You will need to stick your flat tool into the crevice, work it down into the crevice,and then pry up so that the casing separates. Apply enough pressure so that your flat tooldoes not slip and scratch your iPod!Continue separating the casing by gently prying up all the way around the unit. It shouldbe much easier to pry the casing apart after you get the initial corner started.

With the casing separated, grasp the top half (the part with the front bezel) and flip it over. Note that there is an orange cable in the top left corner that connects the iPodlogic board to the headphone ports. If you gently grasp the cable and pull, it will slide out of its connector on the headphone port module board.

Headphone Jack Board Removal Before proceeding, you must remove the top case.There are two t6 screws holding the headphone port in place. Remove both of these screws. You can now remove the headphone module.

Hard Drive Removal Before proceeding, you must remove the top case.Hold the hard drive up, and remove the black tape on the hard drive connector. This will reveal the hard drive cable’s connector to the logic board.To remove the hard drive, grasp the cable (thumb on top index finger onbottom) and gently pull the cable out (away from you and the connector)The hard drive will now be free of the iPod logic board.

Hard Drive Cable Removal Before proceeding, remove the hard drive.To remove the hard drive cable, hold the drive, and gently pull up on the cable.It should come out easily.

Headphone Connector Cable Removal Before proceeding, remove the hard drive.To remove the headphone connector cable, Grasp the cable, and gently pull up. It should come out easily.

Logic Board Removal Before proceeding, remove the hard drive and headphone connector cable First, disconnect the battery connector by grasping the cable and gently pulling up to disconnect the cable from the logic board connector. Remove the 6 black T6 Screws.
With the screws removed slightly move the logic board to the left to give more access to the clickwheel cable. Gently pull this cable to free it from the logic boardconnector.The logic board will now easily come free from the case. The LCD will still be attachedto the logic board.

LCD Removal Before proceeding, first remove:Hard DriveHeadphone Connector CableLogic BoardTo remove the LCD, grasp the green connector cable, and gently pull to free it from the logic board connector. It should come out easily.


Battery Removal Before proceeding, first remove:Hard DriveHeadphone Connector Cable Logic Board To remove the battery, use a flat tool to pry the battery up. It is held on with a lightadhesive, and should come up by using just a little force. Lift the battery out of the unit.


Everything goes back in with gentle pressure and of course replacing screws and what not. All in all though, it is allot cheaper then buying a new iPod or other MP3 player :) I hope this is helpful to you

Unplug the operator for 2 mins.and remove the wires to the wall control. plug the operator back in if the operator starts running  the logic board is most likely fried (bad) and should be replaced.

If it really is a "logic board" problem, then it's time to responsibly recycle the printer, and to purchase a brand-new printer; hopefully, you can find one that uses the same ink-cartridges as your current printer.

A "pro" would charge you $50 to $100 to _look_ at it, with _no_ guarantee of being able to fix it; instead, invest that money in the new printer, which you _know_ will work.
