Won't Turn On

In order to figure out this problem, I would need a few more details - in particular what was actually happening just before the shut-down, and if the machine will restart again if left for a while. If you are using a memory card and the machine turns off as it is trying to load software from the card, then I suspect a corrupt memory card or a corrupt file on it. Best way to easily check this is to aquire a second card - ideally if you have a friend who has the same machine that seems to work fine - ask if you can try out their card. (Please make sure that everything is backed up onto a PC or similar in case). If this appears to solve the problem, then reformating your memory card and copying your friends card to yours may be the solution. If this doesn't work then possibly the card itself has failed. If you are not using a card, then the two most likely problems are the internal software or the power supply. Stopping during operation at random, and then turning on again after a while would indicate an overheating problem in the power supply - I have been unable to identify the type of supply myself - if it is an internal supply similar to a PC (with an exit hole in the machine for hot air) then a failed fan is often the problem which should be able to be replaced by any computer shop. If the transformer is of the external type (usually a black box half way along the power cable) then a fan is rarely used - but these transformer units can often fail due to small electronic components or fuses especially if there could have been a power blackout or electrical storm while the unit was plugged in. Usually not worth fixing, these power supply units can be replaced relatively cheaply. Internal software crashes may be able to be repaired easily, but with a specialist machine such as this I would recommend contacting your local dealer - they may not have an expert but should know how to contact one. A first port of call should be; http://www.janome.com/helpdesk.php As they provide a number of software updates and fixes which may solve the problem simply by downloading and installing a small patch correction for the operating software. There are several available for different operating system versions. If you are unsure how to proceed with this, then please find a friend who knows how to download and install software from the internet - it is not an overly complicated operation. If these measures do not seem to help, and if the shutdown occurred when actually sewing/embroidering, then the electric motor itself may have a fault and be overheating. If it turns back on when cooled down, then the motor is hopefully fine, the shutdown was probably caused by a protective cutout designed to save the motor and probably leads back to a power supply problem. In summary: 1. Check if the machine turns on after leaving it for a while, then shuts down again. This almost certainly is a power supply problem, although there could be operating software issues. 2. Check/remember if the machine turned off whilst it was trying to access a memory card, and if possible try with another to see if the problem recurs. 3. Go to the http://www.janome.com/helpdesk.php and check for software fixes/issues armed with all the paperwork that identifies your operating system version. 4. If none of the above solve your problem then I suspect a problem in the motor itself or a motor protection device. This is likely to be best fixed by an authorised dealer as they should have some experience of these problems on your model. 5. If the machine is still under warranty, then please try and get it to a dealer, as any internal investigation may invalidate the warranty. Software updates and fixes, or replacing an external power supply should not affect warranty however, so are worth trying yourself. Hope this helps.
