Hello, long time lurker here.
I got an old ILI9325 Dingoo for a few years already. I lent it a friend for a few days and guess what, broken...
He said it worked in the evening, then on the morning connected it to his pc to charge and load some roms, then discovered the fault later. So it must've happened when connected to the pc, maybe a dodgy cable or so.
It does nothing right now, only sits there with the black screen staring into my soul. I had a short dingux screen once when connecting USB but it disappeared after a half second. Nothing since then.
Opened it and had a look, everything looks great inside beside some dirt. Checked with a multimeter if the USB port gets power when connected (it does), if the battery is connected (it is) and some resistors or whatever. Total electronics noob here...
Edited a lent pic from dingoo scene to show what i measured where:
As you see 3.7V everywhere I checked except in the upper right black box (lol told you i'm a noob), where only 0.2V are measured. Now i wonder, is that normal or not? The solderpoint is quite big too on the right side of that thing. Oh and before i forget, reset gives me 2.3 V and Power has 3.3V.
Has my Dingoo a chance to survive this?
