Just looking at the power supply and inverter board from a Samsung P2270HD Tv and reading up it sounds like faulty transformer on inverter part of PSU namely a TM-09180 (transformer) The power unit is a IP-54135B. As the Tv comes on and inverter lights for around 2 seconds and the screen goes off.
 Does anyone know what the resistances of the coil should be?
Regards Anthony

Strangely enough i have just been looking for the schematic and that power supply schematic was the only one i coud find that was close. Unfortunatly the power supply is a different model it is the bn44-00232d pretty similar though. I think i will order a new transformer for it though just been reading from a polish site saying someone had put a TMS91429CT transformer in place that worked. Those transformers are more widely available on ebay as i don't have an account with chs, ohms supplies or wiltsgrove.
 Just unsoldered the inverter transformer and one of the secondary windings was high resistance one side was 1.1k the other side 10k! Problem solved.

 Now just to find the inverter transformer TM-09180

might not be much in it, price wise, to pick up a used " guaranteed working ! " psu from shop jimmy or flea bay . With the benefit if something else has gone too in your old psu your still up and running

Just been searching and ebay from china (unfortunatly) around £12 delivered.
 Power supply outputs all ok besides inverter side so will probably order shortly.
 
Update
Transformer arrived 12days after ordering and TV now working :)
 
For anyone interested primary resistance of inverter transformer TM-09180 around 0.8ohms two secondaries both 1100Ohms
