Sharp 52LE64U power board schematic

Sharp 52LE640U initially had dim screen on right side then after week or two, all black screen, no sound and 1 long, 1 short code. I know that may indicate bad LEDs. Then held Ch down Vol up buttons and picture and sound come on with very dim right side of screen.. Took back off and can see through the numerous small holes in metal back that all leds on right side (left side from front) appear to be on and all the holes on left side (right looking from back) have the same very dim light showing so I think maybe the entire right side strip is off.. I think that dim light may just be the brightly lit leds on the other side casting dim light all the way across the screen to the other side. I tested voltage at the led voltage connector and one set of red/white wires has voltage of about 60-70v with some fluctuation and other set of wires seems to have no voltage. I cannot find a good schematic of the power board to check more voltages. I am thinking about disconnecting the led voltage wire connector and then carefully jumpering the set of red/white wires that has voltage to the red/white wires on the side with with no voltage to see if the dead leds lights come on. That might prove whether its a voltage problem or an led problem, Any comments? I think if it's proven to me that its bad leds I'll give up as to cotly and risky to fix but if it's a bad component on the power board, I'd like to replace it or the entire board. I'd like a good power board schematic with voltages. What I find online in "service" manuals seems odd and not useful. Any comments?
