Yes, the TV switches off completely - no sound or pictures - but switches itself back on within a couple of seconds.
The TV is just out of warranty and Samsung have already said that I will have to pay for any repair.
If the logic board was defective wouldn't this also affect the TV when tuned in to the TV's own input - i.e when set to "TV"?
How easy is it to replace the logic board? I have taken laptops apart in the past to replace various modules./ Would this require a similar level of expertise?
Where can I buy a replacement logic board?
Any idea of typical cost/
Thanks for this suggestion.
I bought the TV almost 4 years ago on 2nd August 2011, so it is well beyond the warranty period.
I could try the EU legislation but this will probably involve a very drawn out period of negotiation during which time I live with the TV that is driving me mad! It may be easier simply to replace the Logic Board.
Any suggestions how I could purchase the right one? Or is this likely to be available to 'authorised' repairers only?
