Send private message to Dr.Joe he has his own website dedicated to the F38310 and a few hyperlinks to help. To disable the Scan Velocity Modulator you will have to take off the back panel and unclip the orange wire and leave it hanging, then put back on again. What I did was to move the sharpess to zero as this is the activating point of the SVM. I have a open box and warranty has nearly run out but I don't need to pull the heavy on your back set out to do the above, I am satiisfied with what I have done. View is great I use a Progressive Scan DVD player w/built in line doubler, rather than forcing the set to do a 480p.
