Hi!

If you have a nice locked picture, then what happened is that you made a mistake
with replacing parts and the sync is getting to the H Osc. out of phase, or delayed
because there are 2 parts in the wrong spot and an RC is charging & discharging
in a way to delay the sync and it's showing up in the middle of the screen.
It's locked to the sync pulse as you can see it's pretty perfectly straight.
I think the best way to find this is to Check the wiring, Look for wrong
parts in wrong spots, etc.
