Was Hoping One Bad Tube Would Fix It
I removed the vertical osc. tube 6SN7GT and the vertical output tube 6AH4GT and had them both tested . The 6AH4GT tested fine but the 6SN7GT was below minimum output and was shorting out intermittently. I thought just maybe,just maybes would solve the problem and I would get "snow" on the screen . My luck ran out when I turned the tv on. I have the same basic pattern that I did before. What should I do next, check/replace capacitors? Thanks in advance for any input. tv10.jpg

for starters you still need to turn the brightness down berore you burn the screen.
If it has paper caps you will need to replace them, no point in trying it any more until you do that. Next would be to check the electros esp any that are cathode bypass in the vert osc circuit. You could also check for continuity of the yoke and windings of the vert out transformer, but paper caps are 1st.
