My Proscan LED flatscreen TV will not power on (rarely turns on) (model number: PLDED3273A-C) I plug it in and the power indicator on the bottom right hand side instantly turns blue and it stays blue for about 3 seconds and then turns red for about 2 seconds and then it turns blue again and this repeats, I have rarely gotten it to turn on by fiddling with the power button but 99.9% of the time I have no luck, anyone know what the issue could be? thanks.
