Atomic Punk PCB radio over speakers

[Robertguy09]

Hi everyone,

I just got myself an Atomic Punk Global Quest and when I connect it to my Blast City, there is some radio broadcast being picked up.
Has anyone seen this issue before? Any solutions to this?

Here is a video of the issue: https://photos.app.goo.gl/rrrKQ1Y39yivP3tq9
It seems to come in more clearly as I touch the volume pot.

Thanks!
Robert

I doubt this is the issue, but I did notice a cap was broken off in the audio area.

Anyone know the value of C210?

C210 is 100uF 25V.

C210 is 100uF 25V.

Thank you so much!

Do you know where I can find a diagram for this board?
There are a few caps that looked to have leaked and I would like to recap all the board. Only problem is I can't figure out the values. The caps all have a code on them, rather than the value and I can't figure out how to translate them.

For example the picture I attached, the cap has 9214 CE105°C. Or if you know how to translate that, it would be greatly appreciated!

You sure? The values should be written on the other side.

Anyway,

C201 220uF 16V
C202 1uF 50V
C203 470uF 25V
C205 22uF 25V
C209 47uF 16V
C210 100uF 25V
C214 1uF 50V
C216 1uF 50V

oh you are right! It is there! It was just covered in so much corrosion I couldn't see it.

Thank you for the list !

Turns out the issue was just all the bad caps! I replaced them all and it is working perfect now!

Thanks again for your help!
