Hello I am tryig to repair a broken guitar fx unit
It was bricked and I programed a memory chip for it (25q32)
I soldered it on and it worked but only for a few minutes then the Ui functionallity started to decay slowly until it was completely dead
by resoldering the chip most of the times it works but only for a few minutes.
If I resolder and dont turn it on for an hour then it will work and decay (so time from soldering does not matter)
I checked the chip with thebios writer and it seems ok .
maybe the device is malfunctioning somewhere else but I really dont understaund why reheating the solder joints on the 8 pin bios memorys chip would cause it to temporely fix
could this be a bad capacitor?
I am not an electrisian so I dont have expiriance with repairing espesialy smd
I can not provide a schematic of the unit , it is not publikly available its main component is a ti dsp.
sorry for any bad spelling.
