moebius Posted April 21, 2006 Report Share Posted April 21, 2006 Hi,No - This is not normal. What kind of Power Supply do You use? The combination of the modules and LCD should not take more than ~1A current, how much is your adapter rated for? Moebiusp.s. Some PSUs have thermal fuses in them, so they switch off if loaded too heavily and back on after the PSU calms down.. Quote Link to comment Share on other sites More sharing options...

moebius Posted April 21, 2006 Report Share Posted April 21, 2006 Then there is short somewhere in Your boards.. do a visual inspection if you can find a bad soldering and then use multimeter to check if there's short circuit somewhere.Moebius Quote Link to comment Share on other sites More sharing options...

smashtv Posted April 21, 2006 Report Share Posted April 21, 2006 i notice that adaptator burn only if i play soundout of the sid.You have a power and or ground path from your SID to your amp, or your CORE to your PC, or both, or your CORE+SID are making a path from your PC to your amp, etc.The burnt out wal wart thing is totally related to your "display stays lit" issue.....Did you lift the ground on the CORE MIDI yet like I suggested on the lit display thread?BestSmash Quote Link to comment Share on other sites More sharing options...
