techknight - good call. Will have a look at them tomorrow. Just a continuity test between 2 via's on a single trace - will do

-

0.1uf - that's great to know - will install new one tomorow

-

that chip at the bottom of the picture is the rage ii graphics chip. The legs of the chip were coated in some corrosion from the acid. With a magnifying glass allot of them looked to be shorting

-

I have spent a hell of allot of time cleaning that chips legs with acetone, a toothbrush and flushing the legs clean. Spent 30min with a magnifying glass and a pin going between each leg

.

But the display has not changed one bit since the first time I got it going.

-

nothing has changed ...even after a full recap

-

but ill have another look tomorrow............what ever it is it has to be 1 or 2 or 3 small problems for the machine to be flashing the disc icon
