I am returning a UN40EH5300 to Amazon, because on unboxing and powerup, I knoticed there were two spots in the middle of the screen that looked like "poking our fingers" could have been the culprit, but as an engineer, it looks like non-uniformity in LED backlight or screen layer build / manufacture.
Because I noticed this right away, Amazon is making it extremely easy for me to return the unit. Hopefully the second unit I receive will be OK with respect to the screen.
Now if only the SMART Apps worked with the keyboard in a uniform manner. Ouch! The YouTube App needs a complete re-write.
We bought a Samsung UN40EH6030 40-Inch TV from Amazon in 11/12. We loved the quality of the picture & features. In late April 2013, a grey smudge 1/2 the size of a dime appeared in the center of the screen. I submitted an online repair request with Samsung on 5/2. After nineteen days, six e-mails, several phone calls, two repair services, three conversations with 'Executive Customer Relations', two different 'ticket' numbers and one review by the mysterious 'Panel Review Board', I've been advised that they will not repair our TV, and that there is no recourse.
Why? They're claiming physical damage, even thought there's not a mark on it. Someone poked it with a finger, they say. My wife is 60; I'm 62. There have been no other people in our home since 2/2013 other than the Samsung tech. And we're not prone to poking our fingers into TV screens. An interned search of this problem indicates a blown led/lcd, but Samsung won't discuss it. We're stuck, and that's it.
Btw, no one at Samsung knows what is going on. The evening of the day the tech was here, I received a call from Samsung asking if I was happy with the repair. He had no idea that it was still in limbo. The day the repair service called and told me that my repair was denied (5/17), I called Samsung and was told that my complaint would be sent to the 'Panel Review Board' and that I would be contacted by Samsung within 24 hours with a decision. So I waited. On 5/18, I received two e-mails. One was a survey asking if I was satisfied with my repair & service. The other, sent later, told me that a new ticket had been opened and that a repairman would be contacting me. On 5/21, Samsung 'Customer Support' called and asked if the 'Executive Customer Relations' people had called back. I said no, I was still waiting. She advised me to call them, stating 'They won't call you'. So I did, and was told of our fate by a nice lady who had no inkling what was going on. And she told me that I could not talk with the 'Panel Review Board' to discuss the discrepancies in the repair report because they could not contact them! She also refused to forward me to a supervisor.
Bottom line: Samsung will sell you a defective product and refuse to repair it. They'll snow you with e-mails, meaningless conversations, and hope that you'll become so frustrated that you'll give up. In our case, the message is clear;:'It's not a big problem. Better learn to live with it, because we're not going to fix it'.
Learn from this, people. Don't buy Samsung.
