5" missing video on top of screen that "was" pulsating up and down is
gone; C559 220/35 reading 42 was the bad guy. I still have an inch or so
of vertical distortion (pulling to the left) at the top of the screen.
Also 1/3 of the screen seems to be brighter (flickering also) then the
rest of the screen which has a stable image. Now to find the bad cap,
changed seven now and I still haven't found it. Any ideas?

Oops...wrong model...should be YAMED204C. What is the chassis number for
this? Anyone?

Top of Screen
Hello Techs,
Unit came in with vertical lines top of screen. Replaced usual suspects
around vertical deflection heatsink, C451, C453, C455, C458 and a
.1uf/50V cap (forgot its board location). Anyway now I get vertical
distortion at the top of the screen while viewing a channel. With just a
blue screen (like from a VCR menu) I can see the top 5" of the screen
pulsing up and down, I rechecked all caps and verified the charge-pump
circuit is working properly. What am I missing here? Another cap?
Thanks,
David Lessard
