I know it may seem like a very stupid question but have you tried using a different AV lead? There may be degradation in the wire or a short somewhere causing bad images.
Only other reasons I can think is possibly the modification chip has damaged the system (Pretty common problem I've heard of for PSOnes) or maybe the port for AV cable has been damaged slightly on the "motherboard" due to a drop or yank of the AV cable.
A video of the console in action taken with your phone or something would help a little to see if it is interference, lack of signal power, damaged circuit or chip damage etc.
But would recommend trying a different AV cable first =)
It takes me hours to rip, test, compress and upload games but it only takes a second to click the thanks button so don't forget to say thanks =)
