good luck. I checked my warranty and it is only 2 years on the tube. I really don't think it is the tube though after 4 years, unless they make them a lot cheaper than in the past. I've got tv's that are 20 years old and the tube is still fine.

Anyway, not sure this is something I will be able to troubleshoot or fix on my own, so I may call the place I purchased it and see what they tell me....
