The TV does not get a picture or sound for about 5 minutes after it is turned on. This does not happen all of the time. It primarily happens the first time it is turned on during the day. Other than this problem the picture is excellent. The cable connections have been changed but it still does this.
There is a bad capacitor or a bad connection some where inside this TV set. This will be a hard thing to trouble shoot unless you have some type of solid state experience dealing with printed circuit boards. Please seek out a tech to asssit you in this repair.
