Samsung TXN2745FP 27" EDTV Monitor/TV with DynaFlat Picture Tube
YES! degaussing your picture tube is the answer:
Concerning the &quot;electronics fan&quot; from Kenner, Louisiana USA:  the Samsung set not &quot;firing RED so everything was green blue or purple&quot; is a common indication that your first set needed to be degaussed if it was not firing RED while having vague splotchy colors of green blue or purple. Your second set also needed to be degaussed as you came to understand. You were rightly instructed &quot;to (first shut off set) unplug the TV, wait 30-45 seconds then plug in the TV once again.&quot; However, going through &quot;this procedure 3 times thus far with varying results&quot; also indicates that the degaussing process is not yet complete. There is no big mystery about degaussing. &quot;Degauss: to remove or neutrallize the magnetic field.&quot;(from Merriam Webster's Collegiate Dictionary.) It is as the electronics fan from Breaux Bridge, LA stated on this site that the degaussing circuits control static buildup around the picture tube. Reread &quot;THE NEXT DAY:&quot; paragraph of his January 31, 2004 review article.  Fore I too have a Samsung set and even had to shut it off and unplug it overnight. The next day I plugged the set in and turned it on to find brilliant natural colors. Therefore, I suggest that if shutting off and unplugging the set for 30-45 seconds and restarting it a few times using that technique, does not fully degauss the set---leave it off and unplugged overnight so the static buildup has enough time to discharge.  Do this and the next day Samsung's degaussing circuits should clear up what buildup of static may remain.
