I asked if that was normal and was told that yes, it is a common problem with these sets.
I haven't seen any threads so far with this issue. Has anyone experienced this? My concern is how expensive an LED bulb will be when not under warranty.
Thanks for looking,
I had the exact same thing happen to me about 3 weeks ago. Like the OP, I purchased my set in January of 09. And, like Sean, I too was watching my set (on a Sunday morning no less) and the screen went dark. I knew this couldn't be good. I turned the set up, waited a couple of minutes, and turned it back on. Sure enough the red was missing from the picture. I tried the usual, reset to factory defaults etc, but I knew something had died. So, I contacted Samsung support through their online system. Luckily there was a service center just 8 miles away. The next day I decided to call the service center and see if they had received the service request. The tech I spoke with was very nice, but said that they hadn't receive it and that it would probably be later that afternoon. He went ahead and asked me what the issue was and I explained it to him. Right away he said the red led module had died, and that soon as he received the service request he would order the replacement part. I thanked him for being proactive, and he said that I could call him toward the end of the week and check on the status. On Thursday I called, and he told me that he had just gotten authorization from Samsung to order the replacement part. He said that it's just the way their warranty process works. Another week goes by and he finally gets the part on Wednesday, and said he would come out the next day and replace the module. He came out that Thursday afternoon, and powered the set on just to make sure it was exactly as I had explained. As soon as the screen lit up, he powered it off and confirmed that it was indeed the problem. I asked him if this was something that was a wide spread issue, and he told me that since this model had been released, that he had received only two other requests, and these turned out to be loose led modules that caused a buzzing sound. He said that these have been the most reliable led/dlp based displays to date. He services other brands, Sony, Mitsubishi, etc and his own opinion is that the Sammys are just better sets. I watched him replace the unit and it was fairly straight forward. If you can build your own PC, then you would be comfortable replacing this. The module(s) are about 2"x2". You unplug the bad one and replace it with the new one. You have to slide out the mirror assembly, and take off a large heat sink, and that's about it. I noticed that there was a lot of dust in there, so while he replaced the module I cleaned all dust out of the heat sinks, fans, and any place I saw dust. I did notice that there are 3 fans. One that blows on the main board, one on the heat sink for the light assembly and one exhaust fan on the back. He put everything back together and sure enough I had my red back. To be honest, after watching it a couple of minutes I noticed that it was actually too red. It now had a red push the made the whites have a pinkish tint. I asked the tech about it and he kinda shrugged it off and asked if I had changed anything. I told him that I had only set it back to the original factory defaults. He said that was probably it and left. I new he was on a tight schedule and had squeezed me in at the last minute so I just let it go for the time being. I watched the set that night, and the more I watched it the more I realized it just wasn't right. I called the tech back and explained this to him. He said that when he got back to the shop he would call me and walk me through a few service menu settings. I told him I appreciated it and thanked him. Instead of waiting on him to call, I got brave and used the guide here for accessing the service menu and adjusted it using the recommended settings. Now I'm proud to say that my Sammy has never looked better. Sorry for such a long post, but I just wanted to share my experience with this issue. I hope it may be of some help to anyone else who experiences this issue.
