You could replace C603 first and if this doe not do it then S901 maybe bad.

Has power but no picture

Good Day, bulldogrice;
Your TV has green led's that light when powered on, observe which ones don't light, they are on the TV's PCB's, in the back (inside) of TV. You should call an Authorized Service Center to get an estimate b4 repair. If want to fix yourself come back. Good Luck, big IRISH.

No picture or sound

Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.

D52W19 No pix, sound good - now green light blinks, no come on

First of all you need to find out which CRT leaked and replace it before any other repairs are done. The clear liquid is conductive and has done damage to the CRT board or boards.
