sound but no picture update
So I brought my tv to a repair shop last week and I spoke with them today. They said that they called Samsung tech service and were told to re-solder the main board and the other board and reset the tv to the factory settings. The repair shop said they tested it and it seems to be working fine now. The cost was approx $329.95. This took about a week for them to fix it. With this repair I get a 30 day labor warranty and a 90 day part warranty hopefully if it's not fixed, I will find out the first day or 2. I asked the repair guy if this is a typical problem in lcd tv's 2 years old and he said no, this is not typical and is not sure why it happened. I will update this forum once I get a chance to see that it works for myself.
