I'm sorry to hear about this. Unfortunately, it sounds like it's not a charging issue, more like a display problem. Replacing the display might work, but it also might be the driver or another circuit problem. Are you adept at component-level electronics servicing? If not, then the advice to replace it with another one may be cheaper than paying to have it repaired.
If you feel that the issue is charging or the battery, here are the instructions for remedying charging issues.
Note that the cause of battery problems can often be a defective USB cable. Please swap USB cables if you have another one. The thicker the better.
If your Kasina will not power on, then please try the following procedure exactly, particularly steps 2 to 4:
- Plug in your Kasina to a "known good" USB power source. This can be a USB power supply or the USB port on your computer, just check that it's working by using it to power another device in your house (cell phone/MP3 player, etc)
- Let it charge for a minimum of 1 hour
- After letting it charge, unplug the USB cable from the Kasina, and leave it disconnected for 15 seconds. Keep the other end of the USB cable connected to the USB power source
- Plug the USB cable back into the Kasina, again leaving it connected to the USB power source, and quickly press the power button on the Kasina
- Your Kasina SHOULD fire up at this point. You can now continue to charge the Kasina, noting the battery "filling" animation until the icon is solid green. While it's charging, take note of the above charging information under Settings/Service
- Send us the values from the above Settings/Service menu
- When the Kasina is fully charged, update it to the latest firmware
If you are able to get it to fire up normally, then while the Kasina is plugged into the USB charger, and before it's charged fully, please go to Settings/Service and tell me what these numbers show:
Batt. Voltage:
Charge Curr.:
CPU Voltage:
USB Voltage:
SN:
FW:
HW:
If you would like to open up the Kasina to have a look around,
it's pretty easy.
