Hi.
I have a Sandisk Clip Sport 8GB over 2 years and was working.
Now when i try to boot it doesnt do anything.
~20 sec hold blackscreen with backlight no boot
~10 sec hold random count (8sec or 9,10) and release the button it boots (sometimes)
~battery is in good condition ~3.7V rating (4V on the probes)
spec. the pcb looks fine (traces,debris,rust)
check caps and resistors good(maybe is the IC)
downgrade firmware no permant fix
At pcb there is a TEST_MODE how i can troubleshoot this?
There is no diagram or schematics about the device. pcb 502-01.01
Any fix?
Edit V.1.43 is buggy somehow (because before was ok)
downgrade to 1.17 partially fix the problem
