Depends.. what is wrong with the A600, and the 2 4000mb's?
Regarding the 3000 you're referring to the front LED board?

Hi Rich
A600 i think needs recap
A4000mbs not sure they visually look ok prolly a trace or so..
and yes the A3000 LED board the leds came off should be an easy solder job
Kipper2k was going to fix the a600 but the shipping costs are silly. If you are willing to look at them I can send them along I'll take it PM from here.
