Resets can be simple such as power on/off to a factory reset which puts the settings back to as delivered when new.
These are always tried before we call in a service tech or arrange for repair.
This is a return to a older previous post: I have the 60 PN60E550 which has start up problems. When I power up the set it takes several minutes for the sound to start but there is no picture. I have ruled out the cable box and remote because the set does the same thing when I power up with the Samsung remote or the DVD player remote. It is necessary to shut down and restart several times before I get a picture to accompany the sound.
I religiously comply with the software updates.
A HD tech made suggestions which did not help but also said to try a factory reset.
Can someone describe exactly what a reset does and how to run it. Thanks for any input
