t.v. loses the picture (goes grayish) but sound is fine. When shut off and restarted it is fine and will run normally for hours until it does it again. Picture quality is excellent between episodes. Runs though a Motorola DVR box and an Onyko receiver. The DVR records programs without picture loss and replays fine even though the actual t.v. does not have a picture during the recording. If picture loss occurs while a recorded program is being watched, when the set is shut off and restarted the DVR reverts back to the point at which the picture was lost.
Recently had the t.v. mounted over the fireplace with remote wiring through the attic to the receiver, DVR and blue tooth in a closet. Did not experience this problem prior to the mounting.
