toshiba wall mounted split

[doorswing]

hi all
got a problem with a toshiba split indoor RAS13SHHP-ES outdoor RAS13S2AH-ES
First visit found indoor leds flashing which my mate looked up and said it was a faulty compressor
sure enough the compressor was red hot so we left it a day to cool.next day we looked again and
you could hear compressor hum but would not run,so we changed the compressor,start relay and
capacitor.
this time when you switch on the indoor fan runs normaly,but as soon as it switches the compressor the leds flash again realy quickly.there is a 240v output from the indoor unit to the outdoor unit but only for about 4 seconds then the lights flash again.tried disconnecting compressor and condenser fan, but same thing happens.beginning to think it must be an indoor pcboard problem as there is no board on the outdoor.
has anyone had this fault and could help.
thanks doorswing

Did you replace the compressor with a new one or with an used one?
Did you check the resistances of the winding's of the new compressor against each other and also against the ground?
If the pcb is delivering 240v between 1&2 it is working normally.. i think..

hi nick
fitted new compressor,found resistance of windings balanced at 4-5ohm,and checked down to earth,all ok voltage at 240v is there for a few seconds at 1&2 but as soon as it switches leds flash like the old fruit machines.
