Led problem

Recommended Posts

due to RED led change there is a major light source change, thus need a scanner to cal PRNU . . .  correct procedure

Since there are 7 Red leds in DKS4 they will  become defective one by one aging / burnt with time. If you don't have nearby engineer or your cannot afford technician to come, YES BETTER SELL IT....   However you cannot find a replacement machine that never has problem . . .My opinion !
