SharpCSPSU blow up etcD609 & 610 are the cause - fit kit 59CSCHASSISKIT also check R707 & 720 in psu also change C604 to 330µ 10v, R638 & 641 to 390R 2W. Check for dry joints scan coil plug on yoke - can cause Q601 go s/c & line drive chip IC201 go u/s. Check chip by measuring across R611 - if low at 15-28R instead of 820R chip is faulty.14-09-04
