A3000 sync/video issue

Second the above.  Clean it thoroughly and try an Indivision ECS.  they're only about $100 from AmigaKit, and will give you additional video modes you don't get with the straight 31KHz output from Amber.  Since they take signals straight off the Denise chip fingers crossed that that won't be affected by the battery damage.  Good luck and let us know how it works out!

If there is corrosion inside your socket, perhaps just replacing the socket will resolve all your issues?  Tough to do however, depending on your skills...

Indivision outputs all video modes at 31KHz or higher via HD15 VGA connector.  Normal 15KHz modes (NTSC, PAL) are scan doubled.  Allows connection to any modern monitor.  It will also give you 800x600x16 colors, 1024x768x4 colors, and a few other widescreen modes: HD720, stuff like that.  Great product!  (as you can tell from my sig I own several of them)

BTW - Workbench 3.9 with all the Boing Bag updates includes the updated monitor drivers, so you don't have to scrape them together like I had to do with my earlier build, LOL.
