Only Samsung has the spare part so do call them. I like to watch 3D movies (blu ray) so i also have a LG 3D Tv.
call up samsung service centre, based on my description to them..the customer service said most likely is panel faulty. They mention only able to advise more accurately with onsite check.
Cost is $210 for transport and labor. not including parts. for panel replacement, easily 1k and above for a 55" screen.
the issue is Samsung is unable to advise whether they have any panel part fo rthis model and told me only technician can advise once he check onsite.
my point to them is if they come onsite n confirm its panel issue, but then said no more such parts, then im spending $210 for nothing. At least if they are able to advise they do keep panel part for this model, at least im more willing to pay for the onsite troubleshooting support.
is this the common practice for samsung/lg/sony to carry out onsite check?
