I'm sorry to hear that you're having this issue. Unfortunately, I'm not able to provide estimates or diagnosis. However, you can either call 800-SAMSUNG or set up a service inquiry online here:
When i turn on my 52 inch samsung lcd 1080p it sometimes gives me a static sound and a scrambled picture. The tv then turns itself off automatically then turns itself back on and off till the picture clears up. This is all done automatically with the push of one button. I have tried hooking it up to differnet components, cables, and input styles with no luck. I did update the firmware, and that seemed to cure it, but only for a few days. This started about two months ago, it would cycle two or three times, 27 yeasterday, and today I let it cycle from 6 PM until 10 PM. The set looks great once it locks in the picture the first time, and I have no issues switching from source to source after the picture is initallyh obtained. Its just my luck that it would fail superbowl weekend.
Any ideas, or at least a cost estimate of what it will take to get it fixed?
