Im working on a Hitachi P60x901, picked tv up with no power. Replaced a couple large caps on power supply. Now tv seems to be powering up, voltages are good at ps. But the screen is not priming? No flashing lights on led, goes from red to blue for about 20 seconds then to orange. From manual I have read that orange indicates no r/c,a/v signal. But shouldnt the screen at least prime first?
