I got your reply...where do I get a schematic for this model? I was a t.v. tech. for 25 years, but now retired....I don't know how to find the service literature for these later brand t.v.'s. Thank you, ralph watson

ApprenticeI have had past experience some years ago with new or fairly new TVs which had vertical deflection failure.
I suggest Checking all coupling capacitors on the circuit board around the vertical deflection circuits. One way to check is to turn the set on and slightly warp the circuit board and see if the deflection restores.
I have found bad solder joins in several sets which lost the Vert. deflection and was simply repaired by re soldering the connections.
