Hi,
Junk it, buy a new one
I rarely tell anyone this, but this is one of those exceptions. If you could not figure out what was happening before, you'll never figure it out now without getting extremely lucky.
If you seriously still want to try to fix this you'll probably have to get a schematic. Maybe tracing out the PC board would help, but without knowing the IC part number it's very difficult.
hi
i respect your experience and your excellent reputation you got here at the forums...but this is not
an advice that you gave...
we don't throw to the garbage or salvage a device before we make sure it's not repairable or time and cost worthy to
do so... worse case scenario maybe you could advice me to use a computer power supply to power up this thing.
despite that...what i'll try to do next is to buy the IC that got burned...i think i'll order the ICE2A265 or ICE2B265
any opinions?
