Hello This is an indication that your vertical output stage is beginning to malfunction. It could be the vertical output IC or the vertical coupling capacitor. I would suggest using the schematic and an oscilloscope to determine if the signal is correct. You may have to replace the IC or the capacitor.
I hope this helps,
