XDA2s defect

[Heinzibua]

unfortunately my XDA2s lost his display light; when i turn my BA on, the display light works for 1/2 second, then the display is dark (can read it, but no light).
does anybody have an idea, what happened ?
regards, karl

1 hold down the power button for a bit to see if you just toggled the backlight off
2 check the backlight power off time in settings

thx, its a hardware problem, i tried everything !
light starts for a moment, but goes to 0 suddenly., if there is not enough current.
i´ve sent this device to a repair shop already; they told me , its a mainboard problem, costs about 200 €, but as i trust in you guys more and hoped to find some other solutions here...

try a new battery first.
it's the common source of hardware glitches.
my first glitch was the phone is always turning off.
that's because the battery cant support its power.

my 10c.

no, not battery, have 2 devices here, changed battery already...

[Heinzibua]

no ideas ?

[SilverSamurai]

i guess you have new battery on the other one?

last culprit could be a lose connection/contacts on the LEDs.

i´m afrid, that motherboard is gone...
i opened this device several times, but can´t find anything strange in there.
thx for your help !
