hi all ive gotone of these torepair for a friend,he put it into a waggon and shoved 24 volts into it,now we have no led display,no tx,sounds like the pll is unlocked,now i suspect there is a 7805 voltage regulator that supplies the smd chip that controls the pll etc,trouble is i can see it on the schematic,but cant find it on the radio,any ideas anyone,its not a mod i know but couldnt see where else to post,cheers Paul,m3vuv.
