wingo help please

[bertie123]

hi, i have installed a wingo kit with a mindy a400 control box and 1 set of photo cells. when the system is powered up the leds flash rapidly for ten seconds then the ok led flashes slowly and the stop and photo leds are on. thats as far as it goes. i press the p2 button to start automatic search but nothing happens. the smxi radio receiver does not light up when the button is pressed to memorise a remote. the system is brand new although it has been stored for about 3 years prior to fitting.do you think it is the main control unit or the smxi receiver.is there any way to get them checked or does it mean buying a new system.
any help will be really appreciated.
thanks
paul
