I have akai aa-m3 and was working perfectly.
I did a big mistake clean it inside and power ON
May be I touch and made a short
I saw white chip from two whit cheaps beside fuses - light inside red like a fire but not burned but was very heat when I touched. My finger is burned
And I smoken something burn but I do not see it.
After that akai deed not work again when try power on.
Please help - I have a manual for it as pdf and I can upload it if you need.

As far as I can make that out through your very bad Ingrish, that sounds like a pretty major power amp meltdown.
Now the unit does not make a peep, no display, no nothing? Then at least one pair of output transistors went completely short (and things are not looking good for the associated µPC1270C and other components). In this unit (no rail fuses) this will eventually take out the thermal fuse in the mains transformer, which can be a royal pain to replace.
How much work are you willing to put into this? It could be quite a lot, and that's not exactly a high-end unit.

Yes

As you said
no fixing for it or there is a way.

Is need to replace for thermal fuse or more than that ?
I see two and One of them Was heated to much and other one nothing
I see two and One of them Was heated to much and other one nothing
As you said no need to make effort to try to fix it
If mains transformer that will be big damage and end of this unit.
It will take a lot of works
Is that correct ?

To find out whether the xfmr is dead:
Get a multimeter. Set it to ohms range (maybe 2k if not autoranging).
Unplug AA-M3. Turn power switch on.
Measure resistance across the AA-M3's power plug.
If you get some sensible value like a few hundred ohms, the transformer would still seem to be alive. Repairing the rest would still be a pain but at least feasible.
I am guessing you'll see something closer to an open though, in which case the thermal fuse would be blown.
In some transformers the thermal fuse can be bypassed quite easily, while others require a lot of work to even access it - no idea which camp this one falls into.
