A600 Black screen
« on: April 18, 2012, 06:20:10 AM »
Hello Ppl. New to the forum.
I have a A600 that is hanging up on power on just a black screen . . .
If i wait enough ( like 5 - 10 ) min or so , it will boot up eventually :laugh1:
i have tried to swap flopy drive even take it off and its the same.
I have even tried to swap the kick start rom from a A500 (kick 1.3)
it was this way that i see it working the first time cose it boot up right away..  but then did the same thing.
 now i have put the original kickstart rom . .
is there any work around to this?
tks in advance
 
I also have two A500 one work ok but other is soffering from the green acid from the baterie leak from expation card its very very green
 
any way to clean ? or the acid corrotes the tracks as well?

Hi there .. no leak near capacitors, however the 3th solid capacitor near the Rf modulator its lose, maybe its this one.. I will try to take it out and replace it or solder it, but now even worst.. yesterday i notice a strange electronic burning smell when the a 600 was on .. but i didnt see nothing today when i power it up black screen , wait then just white  no kick start.. i search and find a very very small (C3 ) burned its shorted out i think its capacitor .. I will post some pictures
I am so sad.. hope i can solve this. but dont know where i will find this small parts.. the A500 its ok .. i take the expantion out and clean with electronic cleaner spry and a toothbrush

hI again
I have finally bought all capacitors i have changed the one that was loose and also the one that was burned "C3" Ceramic one ..
But now it goes White Screen ..
I will try and change all aluminium SM capacitors and electrolitic as well ..
but i found that the line that feeds rhe C3 is burned :madashell:. i fallow it and it goes to the back of the board :hammer:
 
I will have to pass a fin wire to the small hole or aroud the board
 
I am so Sad :cry: about this tiny litle big A600
 
At leat before if I wait enough it will work ...
 
i will post if it works
