I have had this TV for about a year with no problems. One channel started coming in enlarged (subjects cut off at forhead) format OK. I pivked up a new converter to see if that was the problem. When I changed over my screne mode does not seem to work. ie, I cannot change modes. Also, in"Menu" in screen selection, the 4 : 3 Default line is the onlu option I can select. Screen Mode not available. Thanks for any help
Try first to unplug the set for 24 HOURS let us know how you made out. Good Luck
Also do you know what chassis that set uses and the year of manuafacturing was?
