I see Best B. offered a 4 year warranty for 499 which now includes the bulb. This may have been your cheapest repair path.
None of the makers seem to respond to inquiries about dead sets.
Need help. Picture does not appear only sound. As it turns on there is a ringing noise. It will stay on for a few seconds and then reset and cycle continues. There is also a flashing lcd light. What can it be? Contacted Samsung and they offered little help.
