Thought I would give you another bump - I too have this issue that has been happening the past few nights. I found that unplugging it, and plugging it back can allow for a few hours or few days of viewing....but then it happens again. I really do not want to purchase another TV, but in all the searches I have done as lead to either re-solder the whole TV, replace all the lamps, fix a fuse, replace deflector board, and change the power supply...... I guess the red flashing light could mean anything. I you find a solution - I would be greatful to know what your's was. Thanks!
