Without a multimeter, then you are shooting in the dark. Macs are notorious for showing no signs of damage on failed components. In fact Larry Pina, arguably one of the most knowledgeable repairmen of compact Macs (at least published), often recommends a complete board re-cap when the obvious trouble-spots don't resolve the problem.
You seem to be looking for an easy answer, when the reality is, there may not be one, especially without the proper tools. I have given you all the expert solutions to your particular problem. Not that there couldn't be another problem, but those are the "easy" answers.
Have you inspected the inside of the vinyl insulator for singe marks that might pinpoint a failed component?
As for L2, I told you how to fix it: re-solder it. In many cases a cracked solder joint it the only problem, and simply needs a re-flow. Other times, as I indicated on L3, Pina recommends a complete cleanout and fresh solder. And even if you don't see any damage on pin 4 of P1, or P1 itself, a reflow may similarly solve that problem.
Also, C15 is one of the most notorious causes or problems in all the compact Macs in need of replacement. Pina recommends replacing it even if you are not having problems with it.

Otherwise, try searching the forum, I'm certain someone has posted a link to the video board schematics at some point, or just bide your time until that person reads this and provides it again.
And I think Osgeld was being perfectly helpful. You just didn't provide all the details. And there are certainly electronics dealers in AU and you could certainly buy from the US if they didn't. Like osgeld, I rarely notice someone's location. Notice he didn't assume you were in the US, but suggested a location if you were. This is also helpful to others in the US who may be reading and have a similar problem in the future. We're a community here, where our problems and solutions benefit everyone both now and in the future.
