Figured I would share my story on this current subject.
After my pn60e7000 started having the power issues that many others on this forum have had, or honestly will eventually have, I decided to do some research. Part of that brought me back to this forum. Like the others, my t.v. all of sudden had trouble turning on. All I would get was a clicking noise, and my stand-by light flashing in intervals of 2. Only resolution was to unplug the power cord from the back of the television for a few minutes, and then the tv would turn on. Again, the same results as others were experiencing. After reading some of the helpful responses on this forum, I decided to contact Samsung support to try and get an out of warranty fix like others had. Unfortunately I wasn't able to convince the woman to grant me the one time fix. In hind sight I should've been more persistent
Eventually my tv would no longer turn on, no matter what I tried, and since I was getting no help from Samsung on this issue, I decided to take matters into my own hands. My research I mentioned earlier also led me to story after story of people with Samsung televisions having the exact same issue many of us were/are having. So many in fact, that a class action suit was filed against Samsung, which forced Samsung to offer out of warranty repairs for specific models. Unfortunately our model television was not one of the ones (according to Samsung) that had this issue. I think we all know the truth to that. I also found that there was an easy fix to this common problem. Replacing the bad capacitors on the Power Supply Board. So I went through with the DIY repair since Samsung refused to help me. Ended up not going well. Lets just say, it didn't fix the problem, and luckily didn't cause more damage to the tv.
I decided to give Samsung a call again to see if they could help me out. To my surprise, the rep this time issued me the one time out of warranty repair that I've seen others getting. I was really excited! Problem was after speaking with the local tv repair company, they told me they couldn't do the fix under Samsung's dime because I already tried fixing it, and changed parts. I was completely honest with the repair company, and I understand why they couldn't do it as a warranty repair due to the fact that I "modified" it myself. What frustrates me is that I would have never attempted this fix if Samsung would've admitted their fault, and helped me from the beginning. Oh well, you live and learn.
Repair guy came out, and did exactly what I thought. He replaced the entire Power Supply Board. He said with these newer models, you can't just replace the capacitors. Looks like Samsung went from using cheap capacitors in the past, to now just using cheap power supply boards. Way to go Samsung!
I did look online for a replacement power supply. Apparently the entire world is out of stock, because I couldn't find one anywhere. Everyone was "out of stock". All in all it ended up costing me about $350 to fix the issue. I guess that's better than buying a new tv, but still absolutely ridiculous considering this is an almost $2000 tv that is less than 2 years old!
If it makes anyone feel better, the tv repair guy said all tv's made today pretty much suck. It's just whether you get lucky or not.
If I can give any advice to anyone having this issue, just stay persistent with Samsung in regards to them fixing this issue for you. If you get denied, just keep calling until you get a rep nice enough to help. You do need to speak with their ECR (Executive Customer Relations) dept. I believe it's called.
Maybe we should start our own class action suit against Samsung.
Hope this might help someone.
