There is an error code that flashes on front of TV. which is in this case an error 7 which is power related. Also there is a gree LED on the power supply that will flash an error code also. If u look on the power supply U will see a list of numbers 1-13 which list the error codes and what they mean.Usually if it flashes 1-9 its usually cheaper to just buy another TV. because the Power supply , Y-main, X-main will probably run $300 plus core charge.
