Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, the described symptom always points to an internal hardware issue. Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even perhaps a soldering iron?

Hi ,yes I have both a multi-meter and a soldering iron.

Great on the DIY!

With the unit unplugged, open the rear and look over the power supply board (where the power cord is fed to). Visually inspect this board particularly for any bloated, leaky and failed capacitors.

Then determine the board number. Depending on regional version, it would be something like BN44-00375A or PC46CF2_ZSM.

Please post back results / observations of the above once tried.

I would be mobile a good part of today with sluggish/no Internet but would check back when able.

Hi Louie, i apologize for not answering promptly. i haven't done what you suggested, but it could very well be that. should i decided to have it repaired, have you any idea of the cost involved.? and would you recommend someone to perform the work.
Expert:  Louie replied 1 year ago.

Hi again Vic and appreciate the post back.

Factors to consider:

  • • the Samsung UA46C7000WF came up on the market mid 2010;
  • • a newer version may be viewed HERE for comparison;
  • • a used / pulled out power supply from a donor unit would cost something like as shown HERE;
  • • unfortunately, as I am located in another region, I am unable to recommend a repair person in your area but service/repair fee would largely be dependent on the going rate in your location.

However, it may be more to your advantage to consider a Samsung authorized Service Center (even at least for a quote or if available, a flat rate repair fee):

  • • product familiarity;
  • • parts inventory;
  • • repair and test jigs;
  • • standardized service fees.
