Question about Sony KP-53XBR45 53" Rear Projection Television
My problem is the conversion yoke that is NLA got any solutions ? blue horizontal is ok vertical is nonresponsive. help joe
Joe, did you have a tech confirm it`s the yoke? Not a common problem to have a yoke failure, maybe yoke return resistor(s) or possibly bad convergence IC`s, poor signal from DCU (digital convergence unit).

Red,blue and green each have an amplifier IC--Stk392-560 x 2
Replace both IC's for reliable repair.Also,check fuses,location sometimes ps5003-5008. fuse value 3.15 amp. ......T.

BMW rider , My best guess is my only guess ,itook the bulb assembly out to inspect, smells cooked ,all other colors converging.I'm trying to do a home repair w/o professional costs. The yoke is part of the ic board. I tried to locate the yoke assembly used or new and its NLA from sony . thanks joe
