Eric you seem to have a great deal of knowledge on the JVC 48WP30. I went to turn on my TV tonight and it did not have a picture and it made a thump sound (heart beat-ish). I have been doing some reseach and it sounds like it has something to do with "power supply overcurrent shutdown". Are you familiar with this? It looks like the fix is to replace the convergence amps. Is that correct. If so how do you get the parts and how hard are they to install? Any help is greatly appriciated!
