IPod Touch Backlight Is Not Lighting Up – How To Repair It?
I recently got an IPod touch and got it working. Things were working fine until the backlight stopped working. It lights up, but even though the light keys are turned all the way up, the background is too dark to identify anything at all? Can anything be done about it?
Try installing SBSettings, this might fix the problem.
Try restoring or the recovery mode and if that doesn’t work you can try the DFU mode.
This is one of the most common hardware failure problem which is always reported by iPhone / iPod / iTouch users. The solution to this one is replacing / repairing the backlight hardware of your device.
