Hi Glenn, Plese provide your address, telephone number, e-mail address and the place of purchase and we can set this up for you.
My JS8500 has the problem where the screen goes black for a second or two no sound either comes back, I have a geek squad warranty, 1st thing they did was mailed me a new one connect and cable, that didn't stop it. They're coming out this Saturday to replace a part in the TV. The black screen sometimes will only show up every 2-3 days and other times once a day but after spending $2000 on a tv, I'm prepared to go through the 3 repairs required to be able to get a refund and get a different brand. The black screen I'm getting was happening since about a week after owning the tv, I thought it was a firmware problem and stuck with it but now 2 years later it's still a problem, luckily I bought the 5 year warranty.
my 55" Samsung has had this issue since purchase.
See my earlier posts.
Here is a better description:
regardless of input source the tv would go black and lose picture and sound for 2-10 seconds at a time. It would return to "normal" on its own. This got progressively worse to the point it would happen at least once every 5 minutes.
Something else worth noting. If you were quick enough and had the smart remote in hand you could still pull up the Samsung "hub" menu from he black screen.
This told me that it was most certainly signal or input related.
Swapped power outlets
swapped cable boxes
swapped hdmi cables
tried to reset to factory specs
tried to search for updated software
basically narrowed it to the tv
they set up to have a repair facility come out.
The repair guy called me and basically said he is very familiar with the issue and would order a mainboard and power supply for the tv as this is the problem.
Well fast forward to two weeks and the repair man comes out and fixes the tv. No further issues to report after a week.
So, if you have the issue. Its most definitely the tv. Call and get it repaired or return it.
My my issue is now solved.
Hope this helps someone else.
Factory reset solved the problem for 2 weeks. I have the latest firmware.
Now the black screens have returned, and now the screen also slowly darkens after being on for a few minutes. What a piece of junk.
Despite having a "satisfaction guarantee", Best Buy has been no help at all. That's the last time I buy from them.
Just to clarify, dose your screen go completely dark? It sounds like you may be having a different issue. Thank you.
