What has happened is that your shutdown circuit relay has tripped and it looks like it also may have malfunctioned. This however is not the cause of your problem but a symptom. The cause of your problem is an over-current condition caused by one of the systems in your TV, I would suspect the high voltage power supply or the switching low voltage power supply. These are the first places to look, if they are not the problem then check the convergence correction amplifiers. Right now the shutdown circuit is keeping the TV from coming on. If you do not have a background in electronics I would advise you to have a qualified TV technician analyze and repair your TV.
