thanks apm...........tested all vias to pins for continuity - they all check out.

-

this board seems not to have any acid leak, and very little electrolyte damage.

-

the main problem is/was.......(and prob always will be) ue8

-

decided to start from scratch today. So removed all caps, ue8 and the pins from the cap legs I used last night

-

cleaned board

-

used very small wires to melt into via's around ue8 and then to solder onto ue8 legs/pins.

-

many pads and traces gone so hade to use wire

-

my problem (among others) is I just used basic continuity test on each pin on a good board to find any point where that pin would connect.

applied this to bad board

and soldered in the wires accordingly

-

still no joy

-

heres a few pics of where the board is, plus a short vid of what happens when I turn it on

-

and I know the wires are too dam big.............there all I could fine

-

weh hey!
