I blame my blow torch and plumbers solder.....I got solder splatter on one of the smd capacitors and resistors and it was causing a short.... :oops:

It matters not buddy ...we've all done it at some time..
What matters is that you resolved it without permanent damage ..and the job gets done..

Thanks Evan...I am full of them today...nearly smoked an LG I was working on today as I put the single pink inverter wire on the wrong way...that does make it smoke quite a bit.

Anyway back to this fault....I removed the short and fitted the board....I am getting voltage but its way too low, about 5volts from each 24v pin.....and the 3v has now dropped to 2.3v.

I thinks I fluffed it

E Parton:
..Is that 5volts on load ...?
Whats the voltage with the invertor board disconnected ?

scooby-doo:
Hi

Just checked again with and without inverter connected....the 3.2v is back and I have lost the low voltage on the inverter feed....Thats connected and disconnected

I have just checked all 3 pins of D2010 and not getting anything from that either
