Sydney or Wollongong.
Also Schematics to suit.
Power Light Flashes with No picture or sound which Samsung error code relates to Power Board.
A blinking led does point to a bad power supply board! First, Look for some bad caps (capacitors) on the board. They will look bulged on the
top an may be a little leaky (brownish stain).
You should be able to find a service manual @ www.manualzone.com
Buying a power board try www.shopjimmy.com or ebay!
Good luck, hope this is helpful!!!
