ok, sorry to resurrect this one but i have almost identical problem again but this time with A500+.
I bought it as 'nonworking' and after plugging in, i heard a large POP, bang!
opened it up and resistor R408 is blown away completely! interestingly its in same place as the one mentioned above in a500
can someone tell me the value? its the only a500+ i got.
(R408 is next to R401 in a500+)
edit: i just read the thread. is R408=R401 in A500+ too?
btw, BinoX, thanks for the answer, it repaired my a500.
