cleaned the tuner now I have issues

[DaveWM]

it was odd, it would shake badly esp the top half like a bad oscillation, then loose horz and vert sync, then clear up a bit and be ok. sorta like tearing (which is why I was looking at agc) but ownly sorta, and all the time the actual pic was clean, like the sync pulse was getting clipped. I even switched out the converter box to another tv (I have a AB switch) and it was fine on that tv.

I never did put it on the tv analyst since it cleared up, but that was the next thing try.

oh well at least it gone, just a unsolved puzzle.
