You will need to install a convergence repair kit which contains two Convergence ICs STK392-110 and then the associated resistors as usually a JVC will Need at least 1 or 2 of the resistors when the ICs fail. You can get the kit for your model at the following link which has the IC and all the resistors plus step by step detailed instructions on how to do the repair. This kit fits your model JVC

My av48wp34


The AV48WP34 is a lightbox PTV and therein could be your problem with the audio. If the box was removed for testing in the convergence it's possible that not all the jumpers are tight. Look at connection between pin 12 of T921 and K935 jumper for your 28v source I've made that mistake in this chassis before.
As to your convergemce problem it's most likely an amp failure. That unit takes two STK392-110 Sanyo amps and both should be replaced. On this unit convergence is easy through the front of the TV grill. The entire module can be removed for replacing the amps making installation a breeze if you're any good at soldering.
I'd recommend Acme for the amps http://www.acme-sales.net that way you won't get some chinnese knock-off... And you might even want to consider upgrading the amps to some STK392-150's (greater amperage) for greater reliability.

I have a JVC AV-48WP30, and I had a lot of issues w/ red lines appearing on my screen. If your problem is like mine, then you have to find the video processor, which is a small, squarish metal box on the main board right behind where the a/v plugs are on the back, and jiggle it a little bit, maybe stick a zip tie on there. That always made my lines disappear.
