Replacement power board

I had a bad picture it was concave and had red blue and green lines across the screen. The service tech. looked at it and the convergance board wasn't getting power. He ordered a new power board I put it in but the picture is the same. Is there a reset button or something i have to manually reset? We could not find a way to adjust the convergance on the menu screens is that possible to do on the tv in any of the menu options. I have a RCA HD52W59

NEXT TO THE FLY BACK THERE ARE THREE, (CMT) FUSES THE CENTER ONE IS MORE THAN OPEN. THEY DON'T LOOK LIKE GLASS FUSES, THEY LOOK LIKE CM RESISTOR/CAP LIKE ITEMS. GOOD LUCK.
