I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. Normally it will cost at least $75 to have the set looked at by a repair shop (diagnostics). If the part needed to complete the repair is available, that money will apply towards the labor costs.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here.

Please let me know if I can be of further assistance.
