OK So I have a 65 inch tv that was bought about 2 years ago with vertical lines otherwise it is perfect. It was out of waranty and I no longer had the reciept. So we decided to try and fix it ourselves read about the issue which is all over the internet and it said bad t-con board we have model UN65NU6900FXZA . So we ordered a motherboard for it $100 no big thinking that the t-con board was intergrated in the motherboard. well it did nothing so we put the old one back and tried re seating all the ribbon cords etc. still nothing. So I reached out to samsung the the facebook guy Nick was very nice walked me through all the stuff I had already done I told him what we had done to try and fix it he said I needed to go to the samsung tech line and that they would help me. I called them and explained everything we had done and they walked me through the same steps as nick and went in remotley and we found out that they could not see the lines from the inside they were on the screen only . I remind you here that we had told the tec everything that was done to try and fix it before reaching out to them for help ! So then the tec says ok we will pay for a one time parts and labor to fix your tv ! At this point I am thinking wow samsung realy does care about their customers !!! So the guy comes out and he's like Oh I cant fix this tv its been opened I am like what they knew that I told them over and over nope cant touch it ! Ok fine guy leaves I call samsung and Manuel The case managment guy tells me exact words "The Way it was Organized the work still should have been done" So I am thinking great they are still going honnor their word! Then I get a text from samsung saying they will not be able to complete the repair BECAUSE THE TV WAS OPENED! OMG to me this says they were looking for an excuse not to do the repair ! Why even tell me they would Why waste all of our time!!!! it is obviously a problem with their hardware as in it sucks a $1000.00 tv cant even last 2 years I feel taken advantage of they could have just said oh I am sorry you tried to fix it we cant help you and saved all of us a whole week of our time not to mention I who loved my samsung phone will not be doing business with them again ! And I will tell everyone who will listen !!
