A500+ Broken Component !

[NikGrey]

Hi All,
Like many I'm reliving My youth with the Amiga.

I recently bought an Amiga 500+ Rev 8a and found the battery had started to leak - not badly, more like corrosion.
So I changed that for a modern equivalent, I tried the machine again and nothing (same as when I bought it) - a black screen and I 'Think' the green LED is dim. so I started to re-seat the chips after cleaning them (IPA and a fibreglass pen).
To be honest I think it must have been Me who damaged the component.

I would like to know what it is and what I can replace it with if this part is no longer available (I just checked the many PCB's I have here and none of these to be found).

Thanks for the fast replies, it's lovely to find an active forum in times of trouble

I found that Gary was not seated properly, now I get a white screen and a single Green flash of the caps lock.

I understand it's difficult to help remotely as I'm DysonDoctor.com and I often get people trying to resolve a problem over the phone so I'm super grateful for any input from forum members

My sockets, well - Paula and Gary's do have a certain amount of verdigris inside them and Gary wasn't getting warm (not sure about Gary now/yet as I only discovered he wasn't happy in his socket).

And thanks for identifying that ceramic resistor - I though this was what it was but needed expert clarification.

I'm thinking I should re-seat everything again ?
You will have to forgive me if I ask obvious questions as electronics aren't my thing.

Am I correct in thinking that the only thing I need connected to the board is the keyboard so I can see the lights ? the floppy drive doesn't need to be connected ??
I just have the bare board on a quartz kitchen worktop so there shouldn't be any shorting etc.
I know My PSU is good as I usually have another Amiga permanently set up in the kitchen as I'm obviously single and a big kid
