No hum bars. It's a continuous wave.</font></font>

There is no break - it just keeps coming. It's a vertical monitor - so
it is going across the screen(or down/up if it was horiziontal). I guess
if two hum bars mean a filter cap problem - 8 could mean a bad filet cap
problem.</font></font></blockquote>
<p><br>OK, you're saying you have TWO dark waves? Or two greyscales?
Whatever, if there are two of anything the capacitor (8,000 uF) is bad.</html>
