Hi All
Does anyone have any service information/Wiring Diagram for this machine, I think that is a bad mainboard that is stopping it from turning on but as LG seem to have overcomplicated the design it is difficult to tell for definate.
Thankyou
Jem
dug around just in case you missed anything and no cant find a thing
like you i think is a board failure. looks like a 3 phase motor so likely the inverter has gone but the way they seal the board it makes it hard to find or look for blown components
DaveJust to finish this one off:
I suspect that this is a known problem that is not admitted by LG as the old main board had a fusible resistor (approx 3 watt power rating) incased in a fiberglass sleeve that was definatly blown but I was unable to find any other damage and as far as I could tell none of the inverter outputs were shorted. The new main board has got a ceramic block resistor (somewhere in the 5 to 10 watt range) instead.
