Hi, they are a problem to repair, depends what you think you've done to repair it, no doubt you changed the igbt module, but it usually takes some other supporting components out with it, problem is you've got to put it back on the lift to check, if you don't have a very expensive test rig, change it for the KDL16 a vast improvement, but as I read more threads not 100% I've changed many and you can tell the difference instantly, I've had too many bad experiences with repaired ones,

Good luck

Dave
