Also , the other chasis its near identical, but the dont have the same caps, and it does not have that loose part , but definitely the big main cap needs to be replaced as its does look blow, ill post a picture later.

That circled part looks like an inductor NOT a capacitor.

yeah i think it is, but it only had broken solder, which after i fix them the chassis worked, but with a flaw image, ima do a full cap restoration, and hope that fixes the image. I just need to know the equivalent to the c225 yellow cap.

You've probably already cleaned it up, but it looks like some solder splatter from the overheated coil may have shorted the 2nd and 3rd traces below L301.
Even if your multimeter shows no short between the traces, microscopic solder globules can create an arcing short-circuit path when power is applied and more current/voltage is passing through the traces.

Yeap i fixed that since day 1 , and the chasis turned on with a bad image, you can see that in the video i uploaded on the previews comments, now I just need to know the equivalent to the c225 yellow cap. as im gonna do a cap kit on the chassis.

c403? is more in line with the yellow cap.
