maybe one of you can give me an idea where to go , only has a vertical line that you can't do anything with , you can see it react when you do the height , lin , even the expander switch but it stays a line but you see it reacting , it doesn't grown, the output tranny reads ok in ohms , its tough to figure out all the voltages since they aren't writen and this is all there is , no other sams coverage , no service manual , any idea what to do ? should i be looking at the osc ? i don't know the voltages ( all of them on the osc or output they aren't writen on schematic ) l70 seems ok too.
