i think the fly may be bad or a part of it inside

No, the flyback is good: you have EHT and a bright trace across the screen, therefore it works.

could it be possible that one of these chip caps are bad if its one responsible for the vertical timing. i dont know if SMD components chips are known to go bad even if they have many years on them.

SMD resistors and capacitors can go bad just like any other component.

i did notice that 2 what i think are chip caps off the vert ic have like corrosion and to fix that is very hard because they are hard to hold and maybe this is where the problem is and i dont know if this corrosion could kill the connection but i'll have to try and get them off and resolder.

OK:
1) reflow solder pads on these corrosion-suspect SMDs
2) check trace continuity with Ohm Meter afterwards.
Show us some closeup photos of the suspected corrosion contacts.
If you choose to remove these SMD caps, do you have a capacitance meter?
Check the vertical winding on the deflection yoke. You have the service manual, locate the pins going to the V coils & check for continuity with an Ohm Meter.
On the vertical deflection IC: use your digital VOM to measure voltages on each of the IC's pins vs ground. Compare with the pin-per-pin voltages on the Panasonic service manual.
If really fed-up: send the TV to Andy in TX, he will fix it for you.
