Sold my apexi to my mate , I never noticed that the idle circuit has been damaged

We not opened it yet but might be a loose connection , someone said 35 quid to check it out and might just be a capacitor or something so a cheap fix

Any ideas ?? I'm not a electronics person

I'd go with the 35 quid then St least if they break ir some more they'll have to cough up or fix it

I wouldn't know mate I've chipped X boxes in the past but about as far as I'd gone with stuff like that.
