I just turned on my TinySA Ultra and noticed the touch screen is unresponsive. It does not respond to any touch input on the screen.
Also, the jog-wheel/switch (next to the power switch on the top) is unresponsive.
Frank,
? ?If your tinySA Ultra is less than 30 days old and was sold by a reputable seller, then I would contact the seller about exchanging the unit.? If you have owned the unit for more than 30 days and it only recently has stopped working properly then I would try the following troubleshooting steps.
1. Loosen the 4 screws on the back of the case and see if touch operation is restored.? The case on some version 4.5.1 units fit too tightly and if the screen mounting became slightly misaligned during use, the touchscreen would not work properly.? This same issue could also interfere with USB communications.? The tight case issue should have been solved on your version 4.5.1.1 unit unless you are just unlucky.
2. Completely remove the case and disconnect the battery for a few minutes.? Reconnect the battery and see if normal touch screen operation has returned with the case still removed.? Take normal ESD precautions while doing the above.
3. Check if the flexible cable connecting the display panel to the main board is properly seated.
? If the above trouble shooting steps don't solve your problem, then more extensive repairs are indicated and Erik or hugen may be able to give you additional suggestions.
