How bad was the battery leak?  You've removed & reseated all the custom chips?  Please tell us it was 100% dry from its adventure through the dishwasher (and that you didn't use "heated dry"), before powering it on!  :shocked:

I would remove all accessories and every expansion board, and make sure you're connected to a working display.  Does the "Insert Workbench" logo appear when you turn on the power?

Wait a sec. people actually put motherboards in the dishwasher?
Just curious.

I've done it with keyboards here at the office.  Toss a bunch of them in the dishwasher in the break room when they get too cruddy.  Works pretty well, although if you use the heated dry it cooks them dead, 100% of the time.  Also just a pinch of detergent, anything more than that and it'll bleach the keys and leave them streaky (at least, that's what happens with those generic black Dell keyboards).  Set them in front of a fan for a couple days, flipping them every few hours, to dry.

If OP wasn't super-careful on those above two matters, his board is probably dead (err, deader than it already was, anyway).

For motherboards I use QD Electronics Cleaner, or some similar-type spray.  Never thrown one of those into the wash.  Yet.  :D

What version of Kickstart do you have installed?  A quick google search for Amiga boot colors can give you some more information:

You've posted pictures from every angle except the one that would actually show the damage.  :(

You'll probably need to remove the CPU for a thorough cleaning, and/or replace the CPU socket, if corrosion has reached it.  Perhaps trying with a CPU card installed, which disables the built-in 68000.  Slim chance this might help with your diagnoses...

As you can see for yourself, you're definitely going to need to remove and clean or replace your 68000 socket. Check continuity on that resistor and other components, as well.

Edit:  That 68000 looks like crud, too.  It can probably be cleaned, but might as well just pay the $5 bucks for a 68010 on ebay - they're 3-5% faster and allow you to make use of things like the 'Quit' key in WHDLoad software.  :)

Where are you finding cheap a2000 boards?

"cheap" is a relative term. At least they show up on ebay pretty frequently, which is a lot more than I can say for 1200/3000/4000's. Thanks, hoarders. :(

I will send the Amiga to an expert to repair it!I want the machine back to life...


Good luck. A2000's are durable, but I think when people hear what you've already done to it, most are going to be pretty wary. :(
