sony trinitron tv?

Hi there turned off tv last night, this morning when I switched on the standby power light is flashing green red green red the relays seem to click as normal but nothing else happens apart from led flashing red green.
I have taken of the back and removed the main switch, I am very wary of tv's, give me a steam engine anyday I am fine with them. Help please the grand prix is on Saturday!!!. The model number is kd-28dx0u I am in the uk Paul
