Took the power supply package out of my A2000 to remove a leaky battery on the motherboard, rev6, a couple of days ago. Went to reassemble and test today and made a
(critical) error when plugging in the power supply, in that I moved the connector over by one pin to the left. Now when the machine goes to start up, I get the insert disk screen, BUT, there are white vertical stripes in the centre of the screen. See attached photo. To complicate the issue, I am not sure which way the 50 pin ribbon cable attaches to the A2091. Does the red mark on the cable attach to the top or bottom of the 2091 connector? The unit has a DKB wildfire 060 card in it that had a leaky capacitor some time ago, and damaged the card so that the SCSI does not work, hence the use of the 2091. The machine would boot prior to my little adventure, although it took 6 minutes to do so, but now all I get is the insert disk screen. This is with the red mark on the cable attached to the bottom of the 2091 connector.
Stupid, I know, but can anyone offer any suggestions, other than jumping in the lake?
Making progress. There is what appears to be a display enhancer connected to the Denise chip, and the connecter was not fully inserted into the socket, so now the lines have disappeared from the disk icon screen, but the machine will not boot.
