on the board you replaced the stk's check for bad solder joints, also on the power supply board check for bad solder joints. Don't forget to check all the fuses. If you still have trouble the disconnect the anode from the hv spilter that goes to the flyback. be carefull only do this while the set is off. Then move the anode lead away from everything and try to see if it power up.
