Bob,Since you pinged me, try Radio Shack, they have Molex 9-pins, might have 12-pins, don't know...
(I kid. Thank god they still carry capacitors, or else there's be a few local LCD TV's at the local landfill around me..)
The problem, which is not unique to Samsung, comes from the installation of lesser quality capacitors, Phil said. He explains that the televisions circuits generate around 12 or 13 volts, which overheat the 10-volt capacitors that are pre-installed. The 16-volt capacitors that Phil uses to repair this problem have a higher heat tolerance and thus a much longer lifespan.
