composite video output issue

[xer0510]

hey y'all new to the forum here 

so my famicom has a rolling screen after attempting a composite mod. I've rebuilt the circuit 4 times now and still getting the same problem. I thought it might a sync issue but after the third mod attempt it was working fine until I put its shell back on, the rolling came back. I've checked all my solder joints I've even added jumper wires to the av mod board just in case it had bad traces

This is the board/schematic I went off of. Hope some one here can help me with this and point me in the right direction . I really Don't want to go through the hassle of make a new account to a new forum. Thanks

So this is a DIY solder kit? Are you able to post a picture of your pcb? Also, are there any traces that need to be cut on the console pcb that may cause impedance issues?

Do you get a good picture and it just scolls or does it look dark/distorted in any way?
