We are here to help! If you're unsure of how to diagnose and troubleshoot the TV message or call us for more assistance before purchasing! We offer FREE PROFESSIONAL TECH SUPPORT. The only real way to properly troubleshoot / diagnose is by trial and error since there could be several boards that show similar symptoms and possibly more than 1 board not working. Sometimes the symptoms change. Be patient with questions from us and exchanges!
