We have a Sharp Linytron 25RC169 TV mfg in 9/1990. It's been good and faithful, but a week or so ago all of a sudden the vertical dimension of the image appears to be stretched twice bigger than it should be, though horizontal appears to be a proper fit on the screen. This is the same whether on broadcast or VCR sourcing. I am just good enough soldering to be dangerous to myself, and am old enough to remember taking tubes down to the local drug store to test them. Anyone able to throw any step by step ideas other than take it in, as right now finances make that not-an-option. This is one of two sets I am seeking help on, the second I will post tomorrow when I am awake...
